The Cloudstratus is designed to provide maximum cushioning. Featuring On’s unique CloudTec® system, the lower layer of Clouds absorbs the initial impact of landing before the second layer of Clouds kick in to absorb residual impact and add greater propulsion. The result is a highly cushioned and supportive shoe that also delivers great energy return, perfect for long-distance runs. They’re also suitable for wider feet. It’s running on clouds taken to the next level.
