The Cielo X1 2.0 is built for speed, now lighter than ever. With a propulsive carbon fiber plate, an aggressive forefoot rocker, and nearly 40mm of responsive PEBA foam, it’s designed to help you push the pace. The breathable, lightweight upper features dynamic cutouts to keep things light, while a cushioned collar ensures a secure fit. Finished with a sticky rubber outsole, it offers the traction you need to chase your PRs.
