As much as the Epic React was hailed as the ultimate in cushion and responsiveness, the Odyssey seems even bouncier. We chalk this up to the forefoot rubber outsole adding more responsiveness to the ride of the shoe. But it feels good! It feels like there’s a spring in your step. It’s not to Zoom Fly 4% levels, but there’s a definite comfort and bounce. It might not be a racing shoe, since there’s not that level of responsiveness, but if you’re heavier, the lightness and bounce could make it ideal for speedwork. There is a light stability element, with the rim around the heel having extra material on the medial side, that works in conjunction with a form-fitting upper.
