Ja 4 "Heat Check"
Ja’s elevation is pure hang-time horror, and the Ja 4 packs the bounce that creates unguardable nightmares. Responsive Cushlon 3.0 foam delivers explosive lift and cushions every landing. Its sleek containment system pairs with a supportive upper to help you stay locked in and ready to terrorize any defender in your wake.
Ready for Takeoff
A lightweight and responsive SPRPWR sockliner sits on top of our bouncy Cushlon 3.0 foam for optimal cushioning for those rim-rattling verticals.
Ready for Explosion
The lightweight and durable foam upper provides support for quick moves, and a textured haptic overlay adds dimension and durability. The JA-frame wraps around the midfoot to help keep you contained for extra stability while staying shifty.
Ready for Sharp Cuts
The durable rubber outsole with a logo-inspired traction pattern grips the court like you own it so you can play fast and fearless.
Ready to Inspire
Ja’s words live under every step. His words of “If you are down there” are molded into the outsole, and “I don’t only have motion where my feet are at, it’s global” is seen on side of the JA-frame.
Hot Hand
Once Ja gets it rolling, watch yourself. He’ll turn up the temperature to triple digits—and let you know what time we’re on today. Looks like it’s gonna be a hot one, folks.
