On Cloudflyer 4 Women's Running Shoes

Get ready for supreme cushioning and premium comfort - plus the plushiest tongue ever. It's time to run beyond.

Engineered Mesh Upper

Providing you with increased breathability and constant comfort, the shoes utilise an engineered mesh upper, allowing feet to feel cool and fresh. The re-engineered mesh allows air to flow freely throughout the construction, preventing an uncomfortable heat build-up and ensuring extended durability. This combination of materials will allow you to concentrate on the run ahead and with a 3D moulded heel counted the shoes will remain stable. Additionally, a plus tongue and cushioned collar allow feet to feel secure within the shoes, enhance in-shoe comfort and prevent in-shoe slipping from occurring. Working in tandem, the shoes have a traditional lace-up construction to provide a precise and secure fit.

Advanced Midsole and Outsole

Providing powerful energy return, the Cloudflyer 4 features the signature TPU Speedboard. Harnessing the kinetic energy generated as you run, the Speedboard turns it into momentum, bending and flexing while you move to push you forward, faster. This powerful technology helps to increase your running speed without the extra effort.

Getting started with running - or pushing on to a new goal - can be tough, with dual-density CloudTec cushioning technology and the TPU Speedboard, the Cloudflyer has been engineered to give you that energy boost you need to take you further. Advanced cushioning technology, CloudTec, adapts to every runner thanks to multi-directional Cloud elements that react to your unique movements to deliver soft landings alongside a powerful take-off. This cushioning technology is proven to reduce muscle fatigue and lower your heart rate so that you can run faster for longer. Making every step effortless, the innovative CloudTec technology is constructed using Swiss-engineered Helion superfoam to deliver comfort, support and a more efficient run by absorbing impact, reducing strain and adapting to your running style so you feel like you are running on clouds. Reacting according to your unique movements, CloudTec compresses horizontally and vertically to cushion just where it should. The horizontal deformation of the Clouds as you run does more than just absorb impact, reduce braking force and propels you forward. It also helps prevent injury so you can run pain-free. With advanced production processes, Helion superfoam combines rigid, stable sections with more flexible foam elements along the same molecular chains. This combination eliminates the need for two separate materials allowing you to crush your road runs and shine across any other surface. Helion superfoam provides excellent responsiveness that doesn't sacrifice any comfort and a closed outsole channel is designed for more road and less pebbles.

Finally, the Cloudfly 4s have been finished with a grippy outsole that also has extended low-abrasion rubber pads in high-impact zones to provide you with long-lasting durability and grip on varied surfaces.

Updating their sustainability, the Cloudfly 4s contain 90-95% recycled polyester with a total recycled content of 35-40%. Every shoe, every time - On will never stop pushing to go beyond what's possible when it comes to planet-friendly materials with premium quality.
