The Nike GP Challenge Pro is designed for speed and stability during quick cuts and sudden direction changes on the baseline and at the net. It features a strong plastic midfoot plate and a wide base for stability, with synthetic material on the lateral side to keep the foot contained. Extra rubber on the big-toe side and high-abrasion rubber on the outsole provide durability and traction. A heel Air Zoom unit supports each step. The shoe fits small; ordering half a size up is recommended. Color shown is White/Black/Poison Green. Style number FB3145-105.
