Refined to be even more comfortable and versatile, the On Cloudswift 3 is precisely engineered to adapt to any workout. The midsole now features a dual density construction made from a new Helion foam patterned in their unique Cloudtec design. TPU Injected elements are integrated into the foam to create a highly dynamic underfoot experience and a springy toe off. This update delivers more cushioning without losing the shoe's signature flexible and responsive ride.
