Pushing soft and smooth to the extreme, this cushy new trainer features a revolutionary suspension system with a convex carbon fiber plate that allows the suspension system to compress and spring back with each step. A soft, highly resilient PEBA foam sits closest to the foot for a lively, cushioned ride, while a super critical EVA frame provides a stable base for your easiest miles yet.
