Inspired by Japan's first ever Grand Slam singles champion, these asymmetrically designed trainers bring together the power and good luck of a mythical dragon on the right shoe, and calming wildflowers on the left. These trainers use Nike Claybreaker technology - strenuously tested on red-clay courts across Europe in multiple weather conditions - to enhance traction and prevent buildup on clay courts. A wide traction pattern helps you to control slides and a strong plastic midfoot plate offers stability for quick cuts and added power when transferring energy from side to side. The webbing around the eyestays combines with the plate to offer a “hugged” containment when making dynamic movements across the court. Synthetic material around the lateral side helps keep your foot contained when moving side to side, while extra rubber in the toe area adds durability where it's needed most, with high abrasion rubber along the outsole delivering enhanced durability and traction for a long-lasting wear. Underfoot, a forefoot Zoom Air unit adds a spring to your step while a heel Zoom Air unit provides support. In fact, the whole heel is designed to enhance rocker-like movements -such as pulling back for a serve. Elsewhere, the padded collar and tongue gently wrap your ankle in plush comfort for a soft feel with every step.
