OTIVM's go-to daily trainer for high-mileage comfort. The Chorus RD is a neutral trainer built for everyday runs, with a breathable Vector Knit™ mesh upper that keeps feet cool and light. Its A.I. Fit (Anatomical Intelligence) Last is engineered to relieve pressure off the arch and heel, helping you sit into the midsole rather than on top of it for a naturally supported, cushioned stride. A durable rubber outsole provides reliable grip mile after mile, making the Chorus RD the perfect choice for easier-effort daily runs.

FEATURING: stride flex™
STRIDE FLEX is a multi-functional midsole system featuring 3-axis geometry, dual-tuned high-performance racing foams, and an anatomical contoured last to deliver a fast, comfortable ride—without the need for a carbon-fiber plate.

A.I. (anatomical intelligence) last
The Chorus RD features our anatomically designed footwear last with a raised arch and a rounded heel. The A.I. fit is engineered to relieve pressure off the arch and heel, helping you sit into the midsole rather than on top of it for a naturally supported, cushioned stride.

Our last is designed to mirror the natural shape of the foot through the forefoot, arch, and heel. By allowing the foot to sit slightly within the midsole, the shoe provides a more secure fit and more even pressure distribution for lasting comfort.
