The On Running Cloud 5 All Black is a running shoe that combines sustainability goals with sneaker technology evolution and stealthy style. The recycled content is about 44%, and the construction results in one of On Running’s most lightweight silhouettes. The black upper is crafted from anti-microbial mesh with taped reinforcements for breathability and durability. The lace closure built for speed can be replaced by a traditional lace closure. Hits of silver branding are scattered across this inky upper. What we enjoy most about this shoe is the innovative sole unit. On Running uses Cloud-Tec in a Zero-Gravity foam midsole to provide cushioning and spring with every step. A Speed Board plastic plate allows the shoe to flex with your foot and enhances energy return. The molded heel design keeps your foot secure while the deeply grooved split outsole reduces weight and provides optimal grip.
