In this special GP Challenge 1, the sun shines where you are. Sunflower detailings symbolize vitality, longevity and good luck to start off the year. A metallic Swoosh logo wraps around the heel and a smaller Swoosh design brings flair to the season. It all combines with Air Zoom cushioning and side-to-side stability to help you 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 midfoot plastic plate adds stability for quick cuts and power to your game when transferring energy from motion to motion. Webbing around the eyestays 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.
