Welcome to the newest generation of fast, lightweight, and comfortable tennis shoes. The adidas Women`s adizero Ubersonic 4 Tennis Shoes get an updated fit and enhanced performance to take your game to the next level. A few of the features that contribute to this evolution include the breathable Primeknit sock, lightweight Interlocking Fiber system, and the new Lightstrike Midsole, a major comfort upgrade from past Ubersonic designs. Upper: The Interlocking Fiber system cuts out weight without sacrificing support through the utilization of Dyneema® and Vectran Fibers. A stretch mesh Bootie provides a comfortable, adaptive fit. ADITUFF increases the longevity of the toe area through targeted abrasion resistance. This upper is made from both adidas PrimeBlue (recycled material made with Parley Ocean Plastic) and adidas PrimeGreen (recycled fabrics) materials to create the lightweight, woven mesh. Color: Footwear White and Silver Metallic
