The new  Junior`s Zoom GP 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 and it offers 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.
