Elasticity and cushioning to overcome the defense

Ja Morant's jumps, guard of the Portland Trail Blazers, are a nightmare for the defense, and the Nike Ja 4 is built for that: the responsive Cushlon 3.0 foam gives an explosive push and cushions every landing. The SPRPWR insole, light and responsive, rests on the Cushlon 3.0 and provides the ideal elasticity in vertical takeoffs. The essential containment system and supportive upper provide a stable fit, ready to outplay the defense.

The "Heat Check" colorway

"Heat Check" is the moment when Ja heats up and no one stands a chance: the hot hand. The colorway combines obsidian, Dark Iris, black, and Total Orange, a dark and lively mix that recalls the heat of the game. As in every Ja 4, his words come to life with every step: the phrase "If you are down there" is printed on the sole, while "I don't only have motion where my feet are at, it's global" is visible on the side of the JA Frame structure.
