On Cloudboom Strike LightSpray Men's Running Shoes

The ultrafast Cloudboom Strike, now with On's lightest LightSpray upper. Get ready for serious pace.

LightSpray Upper

LightSpray offers a seamless and responsive second-skin fit. A single 1.5km long filament is spun by a robot to create a mesh-like upper, which is breathable and elastic, with no need for laces. And, at just 30g, it's the lightest upper On has ever made. Creating the upper in a single piece not only creates a seamless, distraction-free fit - it also minimises waste, eliminates the need for glues and emits 75% less CO₂ than other On premium uppers. This means it is ultra-light and minimal, so you get that barely-there feel that keeps you focused on the road ahead.

Advanced Midsole and Outsole

Using On's unique outsole-midsole technology, the Cloudboom Strike utilises strategically placed CloudTec elements to provide outstanding cushioning and optimised comfort, which creates a faster, smoother roll-through experience. This advanced technology adapts to your stride and reacts to your unique movements to receive a soft, bouncy landing and encourage explosive take-offs. Reacting according to your distinctive movements, CloudTec compresses horizontally and vertically to cushion just where it should. The horizontal deformation of the Clouds also reduces braking force. Additionally, the CloudTec elements provide shock-absorbing comfort to help reduce stress and strain on your joints that often occur when striking down on harder surfaces, therefore keeping you comfortable. Working with this, a stiff, spoon-shaped carbon fibre Speedboard works as a springboard, absorbing energy and transferring this into the forefoot. The combined technology adapts to your stride and reacts to your unique movements to receive a soft, bouncy landing and encourage explosive take-offs.

Adding to the super cushioning and comfort, the shoes utilise On's Helion HF hyper foam technology, which is super lightweight and high-performing, to maximise your running efficiency. The compound yields energy to push you into your next stride, providing you with super-responsive strides and returning the energy. The innovative Bounceboard construction propels you forward with outstanding power for a super-soft landing. A removable layer of plush cushioning maximises energy return for a bouncy feeling underfoot, whilst still abiding by stack height regulations. Ensuring grip is provided when racing towards your next PB, a durable rubber adorns the outsole, keeping you stable and secure on a range of road-running and racing surfaces. The rubber is more present on the heel and forefoot, to keep you stable when striking, and enhance the durability in areas that are higher wearing.
