On Cloudswift Running shoes (9, black/grey) - The Cloudswift running shoes by On have been specially designed for the demands of urban running. Helion, a particularly light, soft and agile foam, is used to provide lightness, cushioning and durability. The foam is a mix of hard and soft materials that absorbs energy and releases it again. The patented Cloud elements have also been reinforced with Helion foam and durable rubber. This increases traction, especially during fast runs or on wet roads. Grip and traction are further supported by robust grip pads.The shoes can be put on and taken off quickly and easily because of the special sock construction. The high-quality mesh inserts increase elasticity and optimise stability. The perfect shoe for all urban runners.
