Ja puts in the work to be great so he can be at his best when the game's on the line. That's why we gave the Ja 2 a lighter design. It works with Air Zoom cushioning to help keep him fresh when he's in the lab. And the tractor tire-inspired traction helps him change direction with ease. Ja's about that grind. Are you? With its extra-durable rubber outsole. this version gives you traction for outdoor courts. This gory. grimy design pays homage to Ja's spooky status as an unsolvable mismatch on the floor.
