Ja 4 'Zombie'
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 terrorise 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 ‘If you are down there’ are moulded into the outsole, and ‘I don’t only have motion where my feet are at, it’s global’ is seen on the side of the JA-frame.
Jump Scare
Ja's is yikes year-round—but particularly when it's spooky SZN. This special Ja 4 is a jump scare waiting to scream. We're talking distressed textures, ghost-green shadow and red hits that feel pulled from something lurking in the dark. It's the kind of fear you don't see until it's too late.
