Inov8 RocFly G 390 Walking Boots

Inov8 Shoe Fit Scale

For technical footwear, a good fit is essential to enhance your performance. Inov8's new Shoe Fit Scale makes it easier to find the perfect fitting shoe. All Inov8 shoes are designed with Met-Cradle technology to lock down the mid-foot for a stable hold, where they differ is in the toe box. The shoes are now graded from 1 to 5, Grade 1 representing their closest, most precise fit and Grade 5 representing the widest fitting toe box.

The lower the number on the scale, the narrower the fit, which ensures minimal internal movement of the foot when running fast on technical terrain. Shoes with the higher numbers on the scale will suit athletes with a wider foot and those wanting that extra comfort in the toe box. This wider toe box allows the toes to splay for increased stability when lifting heavy weights. It's also perfect for longer runs and races when toes begin to swell.

Inov8 have graded the RocFly G 390 Walking Boots as Grade 5.

Flexible Knit Upper

The breathable knit upper offers exceptional breathability and quick-drying properties to keep your feet cool and dry. With a flexible fit, the knitted upper adjusts to your foot as it swells naturally during long-distance hikes so that you can continue with comfort. A wide toe-box, plush tongue and padded collar further enhance the overall comfort of this Inov8 hiking boot. The RocFly G 390 has been designed to go all day, every day without discomfort. Extra protection is provided by durable overlays in hard-wearing zones that help to protect your feet from debris and vegetation on your hikes. This upper is extremely lightweight, yet durable to provide supreme comfort and reliability as you go.

The specifically designed lacing system allows for fluid lace movement during on/off. Top speed hooks feature on either side with grooves that grip the laces when tied. This construction ensures a secure hold for a locked-in feel and confident hike.

G-FLY Midsole

The RocFly G 390 Boots feature the world's first graphene-enhanced G-FLY foam in the midsole construction. This will provide you with the ultimate in comfort and response that can be felt mile after mile. The foam will deliver 25% greater energy return, which is guaranteed to give you a spring in your step. This will help feel fresher over greater distances. The boot also features a 10mm deep ADAPTER-FLEX groove, allowing it to adapt and react to the terrain like no other. Thanks to its 6mm drop, the RocFly offers long-distance comfort and makes it Inov8's most cushioned boot yet.

Graphine-Grip Rubber Outsole

Featuring Inov8's Graphene-Grip, the graphene grip rubber outsole provides unrivalled grip and traction over unpredictable surfaces, whilst increasing the outsole durability across a variety of terrain, from mud to wet mountain rock and hard-packed trails, the RocFly G 390 has you covered. The revolutionary Graphene-Grip technology is the toughest and most durable outsole compound that Inov8 has ever created, arguably the toughest and most durable outsole compound on earth. Graphene-Grip is scientifically proven to be 50% stronger, 50% more elastic, and 50% harder wearing. All these features make this Inov8's most sticky but durable outsole yet. 35 multi-directional lugs have been specifically shaped and positioned for improved propulsion at the front as well as braking at the rear. These lugs have a depth of 4mm and have been spaced to prevent debris from attaching to the outsole. Water dispersion channels and rubber dimples provide extra grip on slick surfaces. Completing the outsole are vertical grooves that have been cut into the rubber. These grooves allow the metatarsal bones of the foot to move more independently for an adaptive and flexible grip whilst hiking over uneven terrain.
