On Running produces shoes with a unique feel; its Cloudracer is the lightest iteration of the Cloudtec technology. While not the lightest of racers available today, it’s aimed at providing protection and energy return, and it’s best suited to longer races.
The upper is a gauzy but closed mesh that’s lightweight yet tough, with a suitable fit. On’s outersole technology needs a touch of extra cushioning so it relies on a midsole of a relatively thin, molded EVA (sheet EVA would be too thin). This combination really allows its unique technology to shine. The outersole is a series of lugs covering the whole sole. The lugs, which have a side profile that looks like oval loops, compress under the force transmitted by the footstrike and provide cushioning on impact. Though the lugs add a little weight, they greatly extend the shoe’s effective range and provide assistance in recovering from longer races. The Cloudracer is a solid shoe for faster running and racing.
