Made for the best and those who aspire to be, the GP Challenge 1 helps you serve and swing with confidence. With Air Zoom units and side-to-side stability, it's made to unleash your inner might and smash whatever comes your way when it's match point. Zoom, Zoom A forefoot Air Zoom unit helps you play on your toes and puts a pop in your first step. A heel Air Zoom unit provides support. Stay in Motion A strong mid-foot plastic plate adds stability for quick cuts and power to your game when transferring energy from motion to motion. Webbing around the eye stays combined with the plate offer a sort of "hugged" containment when moving side-to-side. The heel is extra padded to help keep you comfortable and supported. Durable Traction Extra rubber in the toe area, specifically the big-toe side, adds durability. High-abrasion rubber in the forefoot offers durability and traction. We specifically designed the heel for rocker-like movements, like pulling back for a serve.
