The super plush terry tongue fabric is this shoe's standout feature. Part cotton, part technical material; it comes together with a soft cotton-mix upper to create a snug, ultra-comfy fit. Wrapped in vegan leather on the sides for a smooth, clean look. It's made for all-day wear. Zero-Gravity foam means soft, cushioned landings. While the Speedboard® converts the energy generated from each step into forward motion. Basically, it will keep you feeling light on your feet all day long.
