Shoe Technology Upper: Two-tone woven upper creates a unique layer of colors and a contrast faux-suede tongue with diagonal stitching adds texture. Breathable anti-microbial mesh keeps you fresh throughout the day. No-sew taped reinforcements offer a secure fit. Over 80% of the polyester content and over 44% of the entire shoe is made from recycled content. Midsole: Zero-Gravity foam provides a light and responsive ride. Speedboard® flexes as you strike the ground, loading with energy before powering you forward. Increased midsole height and closed channel forefoot offer cushioning and stability. Outsole: CloudTec® elements offer soft landings and powerful lift-offs. Grip pattern adds traction.
