Limited release color way! Meet the most versatile running shoe: the Relay Trainer. It's designed for everything from short runs, long runs, easy runs, hard runs, jogs, walks, and your favorite gym workouts - it's ready to do it all.What's the secret? We've created a cushioned yet stable midsole that combines a firmer outer rim made of Sugarcane-based foam with a softer Algae-based foam center to give you the best of both worlds. Cushion for when you're going the distance and stability for when you're making moves in the gym.A running shoe is only as good as the ingredients used to build it. That's why we've started from scratch and worked closely with our partners to find and develop materials that not only make for a better running and training experience, but also reduce our impact on the environment.The Relay Trainer features a supportive fit with a breathable, non-stretch mesh upper and fits true to size.Bonus: our shoes are unisex, with men’s and women’s styles offering the same fit. This means sizes can be converted to suit a wider range of people. Men’s sizes are 1 full US size smaller than women’s.
