The Nike Women's Osaka Challenge 1 Tennis Shoes have Air Zoom units in the forefoot AND the heel for the ultimate combination of speed and support. The stability is further enhanced by a midfoot plastic plate, which helps with quick direction changes. The medial toe has extra rubber to help withstand excessive wear and tear, and the forefoot is protected with high-abrasion rubber for added traction. The traditional U-throat design provides easy entry and adjustment, and an extra-padded tongue is constructed with breathable mesh for cool comfort. The GP Challenge 1 takes up the mantle of the GP Turbo, offering more volume around the ball of the foot for greater comfort, stability, and balance.

Upper: TPU Cage for adaptable containment. Extra-padded mesh tongue for breathability and comfort. A padded ankle collar helps create a locked-in fit.

Midsole: The Air Zoom unit in the forefoot adds some spring to the first step while the Air Zoom unit in the heel provides support. A midfoot TPU plate adds stability and power.

Outsole: High-abrasion rubber located in the forefoot enhances durability and traction. This outsole is designed for hard court surfaces.

Color: Picante Red and Black
