ace Sea Shadow

All support, no compromises. The ace promises energy return and cushioning in the newest iteration of On's most supportive running shoe.

The Cloudace sports a redesigned Speedboard and brand new geometry. A new Speedboard composition places emphasis on energy return that encourages a bouncier ride. The wider forefoot shape of the Speedboard enhances the overall stability of the Cloudace, promoting smooth transitions on the run.

On uses a blend of CloudTec on the outsole of the Cloudace to create a precisely cushioned ride. The forefoot features Rebound Rubber Clouds that give an added boost to your take-off, while larger Helion Superfoam Clouds at the heel absorb impact upon landing.

A molded layer of foam above the Speedboard creates a contoured footbed that caresses your foot in comfort as you run. The lightweight, engineered mesh upper is secure yet breathable and provides your foot the support it needs on the run.

The ace provides a plush, stabilized run mile after mile.
