The On Cloudstratus is the ultimate in maximal cushioning, for those long runs or short workouts where you just want to soften the ride. A key feature is the two layer system of On's famous Swiss-engineered Cloudtec® sole. The lower layer softens foot strike and collapses to prepare for a forward rebound while the upper layer absorbs residual impact and further propels. If you'd like to enjoy the rest of your day after that morning 10 miler without your ankles, knees and back feeling rattled, the Cloudstratus is your go-to.
