Jargon Buster

Shopping for running shoes isn't always simple and it can be a minefield - especially if you are new to the sport or if you are trying out a brand with which you aren't familiar. So, we've worked with all the key running brands to put together a glossary of all the running technology and what that technology does to act as a one stop runners technical bible.

We hope it helps, and if we've missed anything, or if you have any further queries about just released technology contact us - one of our running shoe specialists will get right back to you.



is an Energy Management technology used to enhance performance throughout the entire footstrike. Maximising energy :use, individually engineered elements cushion, guide, and drive, to deliver the ultimate ride.

ClimaWarm ™

ClimaWarm ™ is about thermal insulation. Lightweight, breathable insulating fabrics keep the feet warm and comfortable when you're out in the cold.

ClimaProof ™

ClimaProof ™ is about weather protection. Combining breathability with wind and water resistance, your feet stay comfortable and dry with fabrics that defend against anything Mother Nature throws at you.

adiPRENE ®

Now think where you need absorption the most - in your heel. This cushioning material under the heel protects the foot. It's technology to reduce the harmful effects of repetitive impact.

Torsion ®

The heel and forefoot are different. They move and rotate independently. The TORSION ® SYSTEM controls this natural motion to create stability and support.


3M-Scotchlite ™

A special reflective material that enhances visibility when light is poor.


Asics high abrasion resistance rubber is a tough rubber compound used at the heavy contact areas of the outsole.

Heel Strike Pod Precisely Engineered

As the heel impacts, the precise angle and bevel of the Brooks heel-strike pod sets the heel up in a neutral position to assure that the heel strike alone does not create undesired lateral motion, especially increased rate of pronation. The crumple zone releases the lateral side of the midsole which allows the foot to remain balanced as it phases into the pressure path. Most of our heel strike pods have HPR, a super-durable rubber compound developed specifically by Brooks for longer wear.

Podular Technology

Brooks' patented Podular Mid-sole/Outsole configurations, MC-Pod, Stable-Pod, Hyper-Pod and Cush-Pod, are engineered to specifically meet the different types of runner's needs. By anatomically engineering a system of "pods" into the midsole and outsole around biomechanically correct flex grooves it enables the shoe to bend and flex more naturally while still supporting the foot at its most critical points.

Substance 257

This unique midsole compound is formulated to resist compression and rebound more quickly after impact than standard EVAs used in other brands. S257 has been tested to be 15% more durable than EVA which means your 400th mile has the same great ride as your first.

:DRB - the Diagonal Rollbar

When the foot comes in contact with the ground, it has a natural tendency to pronate. To help control this movement, we developed the Diagonal Rollbar. This patented, wedge-shaped piece of high density foam is positioned on the medial side of the midsole to reduce the rate and speed of pronation.

HydroFlow ®

Brooks' patented, silicon-based system is the most unique and effective cushioning system ever applied to a running shoe. Its fluid-filled centre chamber dampens shock at impact and dynamically disperses fluid at a controlled rate around the heel - cushioning, stabilising and rebounding on every stride. Plus, it's engineered to never wear out.

DRB - Accel

To promote natural movement between the heel and forefoot, Brooks developed the DRB Accel. This component utilises varying durometers of thermoplastics which provide the torsional midfoot support runners need.

Moisture management fabric technology that moves perspiration away from the skin and disperses over a greater surface area for increased evaporation, comfort and performance.


Design technology that coordinates fabric characteristics with specific sport patterns eliminating stress and allowing for unrestricted motion for better performance.


Thermal dynamic fabric technology that maintains core body temperature, alleviating temperature loss for increased performance.


Weatherproof technology that repels the elements but allows for maximum breathability, comfort and protection, combining fabric with water and wind proof technology.


Mizuno's Wave is the only technology that combines two distinctly different elements that are both inherently necessary in great running shoes - cushioning and stability. Conventional midsoles use flat materials which allow deep penetration at the point of impact. The Mizuno Wave disperses impact forces uniformly over the length and width of the midsole, providing unrivaled cushioning. The Mizuno Wave is a biomechanically engineered midsole technology that resists overpronation, thus relieving stress on ankle and knee joints. Mizuno's unique Wave Technology minimizes excessive midsole collapse as the foot lands and rolls medially providing superior motion control.


Heavy-duty stability footwear that puts emphasis on controlling the foot movement on footstrike. For over-pronators and heavier runners


(BIOMECHANICALLY EFFICIENT) No excessive inward or outward rolling of the foot. A style that follows the natural gait cycle.


Anti-microbial Deoderant for Various Fabrics. NYLON A synthetic fiber that is durable, lightweight and resilient. OUTSOLE The durable bottom part of the shoe which has contact with the ground. OVERPRONATION The excessive inward rolling movement of the foot which can cause injury to the foot and ankle. Overpronators should wear Motion Control Shoes.


The Parallel Wave has improved cushioning, which is further improved on top end models by exposing midsole side wall holes at the heel. The Waves are parallel between lateral and medial sides, with amplitude low and flat at heel strike.


(Lightweight) The Lightweight Parallel Wave has been designed specifically for racing shoes, but still retains all the Wave properties of cushioning and stability. The Waves are parallel between lateral and medial sides, with a short and tight Wave length for quicker conditions.


Flexible lightweight nylon material used in outsoles to provide pressure dispersion and support without unnecessary weight or rigidity.


Lightweight footwear with enough cushioning and stability for everyday use.


A synthetic material, similar to plastics and nylon, which can be used in a variety of applications.


The natural inward rolling movement of the foot in the running gait. Pronation to some degree is normal and necessary, and nearly all runners pronate to some degree, though overpronation can cause injury when the foot rolls too far.


Ultra lightweight speed-enhancing footwear for racing and fast paced training.


The back (heel) section of the shoe which takes the force of impact of the footstrike.


A lightweight fabric, often made of nylon, that has a double thread running through it in a grid to stop small tears from spreading.


A fabric created from elastic thread which helps a garment to stretch for a better fit and added comfort

Footwear with with a good blend of cushioning, medial support and durability. For midweight runners with no severe motion-control problems who want medial support and good durability.


the revolutionary sports material, features a high-density ceramic in the core of the polyester filament. The result? SUNPAQUE™ garments are not see-through and they offer UV protection.


The natural outward rolling movement of the foot as the foot starts to leave the ground. The opposite of pronation. A oversupinating (undersupinating) foot does not pronate so doesn't absorb shock well.


Water resistant, stain resistant, washable and dry cleanable long lasting protection.


A soft, durable nylon fiber that is extremely easy to wash yet allows the skin to breathe.


A strip of fabric sewn to the seam of a garment to prevent distortion. In outerwear, taped seams aid in waterproofing.


The final stage of the running gait where the toes propel the runner forward as the foot is pushed off from the ground.


A knit fabric of exceptional quality, softness and versatility.


The fabric part of the shoe on top that surrounds the foot and holds the laces.


Shock absorption and cushioning. VS-1 absorbs shock and enhances cushioning properties by resisting compression-set, thus extending the cushioning life of running shoes.


Wicktex is a series of high performance technical fabrics designed with special yarn, fabric structure and dyeing process. Wicktex transports perspiration vapour away from the body, cooling down body temperature. Wicktex is comfortable, breathable, easy to care for and durable.


Durablity and traction. X10 provides the most durable carbon rubber from Mizuno that allows for longer wear in high impact areas and provides more traction at heel strike.

Absorb SBS®

For enhanced cushioning Abzorb SBS® is the solution. Its unique cored design and material absorb shock and displace energy to soften the impact foot-strike after foot-strike.

ACTEVA Midsole

Greater consistency in cell size/lower density of cellular foam structure increases resistance to compression set.

C-CAP Midsole

Provides lightweight cushioning and flexibility.


Cushioning core of EVA is encapsulated within a shell of polyurethane which adds rearfoot stability and disperses shock.

External Counter Reinforcer

Moulded TPU re-enforcement that keeps your heel from kicking out from under your shoe and your foot from rolling over.

Graphite Rollbar®

The Graphite Rollbar® is New Balance's premier pronation control device. A lightweight flat or molded piece of graphite material positioned in the heel portion of the midsole, it provides exceptional motional control, prevents excessive pronation and maximises rearfoot stability.

Medial Post

The Medial Post is a wedge of higher than normal density C-Cap material that provides pronation control. The Medial Post most often extends from the heel to the metatarsal head (the ball of the foot) but can vary in length to offer degrees of motion control.


Hard wearing rubber compound used in the heel pad for maximum durability upon heel strike.

N-ergy™ 2.0

A new asymmetrical three-chamber design, N-ergy™ provides a unique supportive cushioning experience as it compresses upon impact

N-Lock Midfoot Support

Designed to provide upper midfoot structure and enhanced support

Stability Web®

Delivers superior support in the midfoot while also reducing the overall weight of the shoe. Made of thermoplastic urethane (TPU) and positioned under the arch, Stability Web allows for torsion and flexion control in the arch while maintaining flexibility in the forefoot.

TPU Post

A stability device made of thermoplastic urethane (TPU), the TPU Post is placed in the heel on the medial (inner) side of the shoe to control pronation and/or on the lateral (outer) side to control under-pronation.


Multi-directional tread configuration provides maximum traction and surface contact.

TS2 Transitional Support System

Provides optimal support while enhancing transition from heel strike to forefoot.


ACG (All Conditions Gear)

Shoes and apparel for outdoor athletes who face elements as challenging as their sports. From a snowboarder's jacket or a trail runner's top to a mountain biker's shorts or a rock climber's approach shoes to... OK, you get it. It's just what is says: All Conditions Gear.

Air-Sole units

Those little bags are based on the following formula: Cu=U+CG. (Cushioning equals urethane bags filled with compressed gas.) Maybe it's not E=MC2, but it will do more for your feet than Einstein ever did. It says that because the gas molecules are larger than the pores in the urethane membrane, air can't escape. The result is our light, protective cushioning.

Autoclave construction

Remember mum's delicious roast? Know how she got it to be just right? Pressure-cooking. Autoclave construction uses a similar process, using high pressure and steam to ensure that our rubber outsoles are just right. But they're not nearly as fast.

Bi-directional lugs

Lugs are traction devices on an outsole. By arranging them in alternating directions, we generate maximum grab in wet, sloppy conditions.

Blow Molding

Used in Max Air cushioning, this process allows designers to make Air-Sole units in more shapes. Gas is injected through an external tube, forcing the plastic into the shape of the mold.

BRS 1000

A highly durable rubber we invented for use in outsoles. BRS stands for Blue Ribbon Sports, which was our name before we came up with Nike. The tie-in? Both BRS and Nike last and last.

Carbon fiber

A material used in midsoles for support. It's stronger than steel, but lighter, which is another reason we don't make steel shoes.


The supporting frame of a structure. In cleated shoes, it supports your foot.

Contoured footbed

Flat feet are so unusual they can keep you out of the army. So a footbed that follows the contours of the foot not only makes sense; it makes sure you can be all you can be.

Contoured Phylon wedge

A piece of foam cushioning placed in the midsole, under the heel, for extra impact protection. So go ahead and make that hard cut.

Crash pad

No, it's not a place where you can sleep for the night. It's a pad on the outside heel of running shoes that helps minimize impact pressure.


An outsole with sidewalls that 'cup' the foot.


It's spelled Dri, but it's pronounced 'dry'. Get it? And dry is what it will keep you. One layer of this moisture-managing material moves perspiration away from the body while a second layer delivers the moisture to the surface of the garment, where it can easily evaporate.

Dual-density Phylon

We have to get technical sometimes. So, we use a material like Phylon and make it more dense on one side to get just the right support. It still cushions. It's just a little thicker -more firm if you will.

Dual-density polyurethane/Phylon

Simpler than it sounds. Midsoles that are harder where you need them to be (that's the polyurethane part), softer and lighter where you don't (that's the Phylon).

Dual-pressure Max Air

Lower pressure = softer cushioning. Higher pressure = more stability. Lower pressure = crash pad. Higher pressure + medial heel. A+B=C. Put 'em together and you've got a great ride.


A blown outsole compound that resembles a foam pad. It serves to provide a cushy ride, and runs from the heel to toe. Techies call it an open cell material that is very porous and lightweight. But you can just think of it as all the cushioning without any excess calories.

Dynamic-fit sleeve

Made of spandex material, it hugs the foot and ankle for improved comfort and support. Another responsible use of spandex that reminds us that this wonder material is a privilege, not a right.

Encapsulated Air-Sole unit

Encapsu…what? Just remember that just because you can't see the Air-Sole unit, it doesn't mean it's not there.

EVA (ee-vee-ay)

Short for or Ethylene Vinyl Acetate, EVA was the foam cushioning used by Nike before we developed Nike-Air cushioning. It's still lightweight and it still provides excellent cushioning. EVA is ay-oh-kay (in a hooked on phonics kinda way).

Fabric wrap technology

Three thousand years ago it was how the Egyptians preserved their rulers. Today it's how we preserve areas of the foot: by placing a piece of nylon fabric between the outsole and midsole to add stability and stiffness without adding much weight.

Flex grooves

Weightlifting to your favourite tunes or areas carved out of outsoles, midsoles and forefoot Air-Sole units to assure an anatomically correct response in the forefoot.

Flexible forefoot Air (aka Flexible Air)

What good is cushioning with flexibility? I dunno, but thanks to compartmentalized air pockets designed to follow flex groove patterns, I don't have to find out.


A device we use in shoes to help slow the rate of pronation. It is inserted between the upper and the midsole. You never know it is there, except when you think of how good your stride is.

Forefoot Air-Sole unit

Nike-Air cushioning placed in the forward part of the shoe. It keeps you on your toes longer.

Forefoot fabric wrap

A nylon underlay placed between the midsole and the outsole of the forefoot to help protect against stone bruising and other objects encountered on the trail.

G-Tek Traction

Oh, this is good. The Oreamnos Americanus joined with our engineers to offer a traction design on edge, literally. They took soft, sticky rubber pads with the ability to conform, and then took hard carbon rubber with the ability to give traction on loose gravel and dirt to create an outsole made for all terrain. Combine that with up and downhill wedging forces and you have a mountain goat.

Heel clip

A V-shaped piece of stainless steel positioned around the heel of the shoe. You pinch it together for a more customized fit. (Believe me, it's a lot more comfortable than it sounds.)

Heel counter

Your heel needs support and stability. Count on the rigid characteristics of a heel counter to provide it.

HF welding

Stands for High Frequency welding. The same principle that allows a microwave oven to bake your potato in minutes allows us to seal air into useful little cushioning and support compartments in our shoes. So you can go work off that baked potato.

Interlocking PU/Phylon midsole

Less geeky than it sounds. Merely a combination midsole that gives you the best of both worlds. Firm PU in the heel provides a good base for those uneven trails. Phylon (Nike's own EVA material) from the midfoot to the toe supplies lightweight cushioning. Less filling. Rides great.

Internal-fit system

Usually involves laces wrapping around and sometimes even under the foot and pulling the upper snug. We think that's fitting.

Large-volume Air-Sole unit

Say it loud: a running shoe is only as good as the amount of impact protection it provides. This unit provides ample protection without weighing down the shoe. Firm enough to protect the heel and still compress to provide awesome cushioning.


Refers to the outside (little toe) side of a foot or shoe.


I could get really scientific here, but I'll spare us both. It's a fiber designer's love because it makes other fabrics super-elastic. You'll recognize it as the stuff that makes biking shorts hug every curve in your body. Which may be a reason to love it or hate it.

Max Air cushioning

It's just what it sounds like: maximum cushioning. Through blow-molding, more pressurized gas can be put inside even bigger air bags. The bigger the Air-Sole unit, the less traditional cushioning material is needed. More cushioning, less weight. You do the math.


Refers to the inside (big toe) part of a foot or shoe.

Memory Foam

Conforms to the shape of your foot to provide a glove-like feel.


An open-textured, breathable fabric, knitted or woven...blah, blah, blah. For our purposes, if it's got visible holes in it, it's mesh.

Midfoot spat strap

A strap that runs across the upper to help lock your foot in place.

Midfoot support system

Any system, internal, midsole or outsole designed to enhance stability in the midfoot area.


Like you've probably guessed, it's the part of the shoe located between the upper and the outsole. It provides the bed your foot rests in, houses Air-Sole units and provides cushioning and support. Think of it as the meat of the sandwich, unless of course, you're vegetarian.

Molded lugs

Rubber pieces on outsoles that dig into ground for extreme traction. Like regular traction on steroids.


Synthetic rubber sponge-like material that goes between two layers of nylon knit to create better insulation.

Nike Alpha Project

A bunch of athletes and other sports freaks designing, testing and developing the best Nike shoes, clothes and equipment on a sport-by-sport basis. The best stuff Nike makes.

Nike Form

Kind of like little bean-bag chairs for the feet. They mold around the ankle for extra cushioning and protection.

Nike Waffle pattern

What's cooking? How about a revolutionary outsole pattern invented by Nike co-founder Bill Bowerman on his wife's waffle iron? We now offer a full-size pattern, as well as, a low-fat mini-waffle. Talk about your breakfast of champions.

Open-weave mesh

A lightweight, breathable material used in the upper that provides consistent, resilient fit.

Optimal Motion flex grooves

A fancy name for a refinement of traditional flex grooves, incorporating grooves aligned along the heel-to-toe axis as well as the medial-to-lateral axis, and resulting in optimal motion during the foot-strike. Ouch, my head hurts.


You know those pontoon things sticking out the side of traditional Hawaiian canoes? They're called outriggers, and they add crucial stability. Same principle here. This refers to a stabilizing device on the outer portion of a shoe designed to keep you from tipping over.


The bottom, outside of the shoe. It gets dirty, it gets abused, and it still provides traction and durable protection. The king of sole, the outsole might just be the hardest working thing in shoe business.


A plastic material that bonds to rubber, it's ideal for use in cleated outsoles because it is lightweight, strong and flexible.


Originally used in dolls, it is a heated and compressed EVA foam cushioning compound that is light, resilient and capable of giving a soft, smooth ride. As a bonus, it is non-yellowing and impervious to attack from water and microbials.What kind of dolls were they?

Polyurethane (PU)

A durable material used in midsoles and other components to help produce stability and a firm ride.

Poron sockliner

A very soft foam insert that adds plenty of comfort.


Check Webster's for the fancy definition. We'll just tell you it's the tendency of the heel to roll inward at each step and that too much pronation can cause injury.

PU coating

Polyurethane is applied like a foam to fabric to give it water-resistant properties. The foam laminate contains air pockets, which enable the fabric to maintain breathability.

Sculpted Phylon

Phylon carved or sculpted, as opposed to molded, to a particular shape. Used primarily in midsoles.

Seamless upper

Like it sounds, it's an upper made of a single piece to increase stability and/or reduce seam abrasion.

Shank plate

Sometimes the forefoot and heel don't want to go in the same direction, which can cause a problem if they're on the same foot. A shank plate, usually in the midfoot area, keeps the forefoot and heel working together to provide more force and stability when you make a cut.


We know you know this, we just want to be sure you know all of what it does: provide even more cushioning. A liner under the foot can add comfort and protection from blisters.


What you'd better call Lycra made by the Dupont Corporation if you don't want to get sued.


Thermoplastic Rubber, a very dense rubber used to make stabilizing sole inserts.


Thermoplastic Urethane. It can be fine-tuned for optimal stiffness and is used to make stabilizing plates.


Wasn't this an old Ziggy song? No wait, it's actually Thermopolyvinyl Resin. Nike's newest technology used to provide stability without adding excess weight. They're lightweight and appear as clear stripes on the shoe. Sounds like something Bowie would wear.

Tuned Air

Newton said that for every action there's an equal and opposite reaction. We weren't about to argue. Instead, we copped his idea and used it to make a supremely versatile and customizable cushioning system.


We don't think you're really looking for the upper on the bottom of the shoe, but just as a formality we'll tell you that you'll find it at the top part of the shoe. You know, the part with all the colors, laces and Swooshes. The upper not only grips your foot and provides comfortable support, but we also tend to make them look really good.

Visible Air-Sole unit

Some people just won't believe something is working unless they see it with their own eyes. So for the sceptics out there, we put our Air-Sole units in plain sight.

Visible Zoom Air

A vacuum-formed polyurethane bag houses densely packed fibers. The fibers, combined with Nike-Air, act as little springs. The result is low-to-the-ground, hyper-responsive speed cushioning you can feel. And it does it in less space than other Air-Sole units.

Women's-Specific Sockliner

A women's sockliner designed to mirror the unique contours of a woman's foot. Slightly narrower in the heel & higher in the arch, it provides a closer fit & more comfortable support.

Zoom Air cushioning

Two layers of nylon fabric, joined by densely packed fibers, are sealed inside polyurethane. The unit is inflated; pushing apart the fabric and creating tension on the fibers. What does that mean? I don't know, but the result is a low-to-the-ground, hyper-responsive speed cushioning you can feel. And it does it in less space than other Air-Sole units.


3D Grid: Soft grade Hytrel™

filaments wrapped around the midsole form a platform for heel strike cushioning and shock absorption.

Air Mesh Upper

Provides breathability.


A construction method in which the midfoot area of the upper wraps over the foot connecting with the midsole to provide superior control and support.


(Blown and Carbon Rubber) Saucony's elite combination of blown rubber and carbon rubber. This lightweight, flexible outsole material provides added cushioning while maintaining durability.

Custom Ride Management (CRM)

Custom Ride Management is multiple variations of a single style, modified to address the athlete's need and/or preferences. CRM allows the user to "define their ride" by selecting their desired level of cushioning or stability depending on the purpose of the shoe and the needs of the individual.

Dual Density EVA

A firm density of EVA located on the medial side of the midsole that slows the rate and controls the maximum angle of over-pronation.

Dynamic V-Grid

Dynamic V-Grid is one singular piece of technology that does the job of four. By replacing all of the individual technologies found in the midsole of most conventional running shoes with one all-encompassing plate, the run is smoother and more effortless. Strobel lasted directly to the upper.

30 degree Grid

Saucony's newest generation of 3D Grid. The Grid height has been increased to run the entire thickness of the footbed. This positions the cushioning properties closer to the foot. In conjunction with this, a thirty-degree angle has been added to the lateral side. Upon heel strike the grid collapses forward to provide a smoother transition, while the medial side remains at ninety-degrees to provide structural support.

Engineered Asymmetrical Sole (E.A.S.)

Engineered Asymmetrical Sole is Saucony's philosophy behind building shoes that are bio-mechanically specific for runners. E.A.S. accounts for each individual component's design and purpose and how they function with each other.
