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.

Athlete-Inspired Details:

• Ja strikes fear into defenders. This obsidian and volt green colorway captures the nightmare moment when he takes flight and the reluctance opponents feel in becoming his next highlight victim.
• 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.

Design:

• The lightweight and durable foam upper provides support for quick moves, and a textured haptic overlay adds dimension and durability
• JA-frame wraps around the midfoot to help keep you contained for extra stability while staying shifty

In-Shoe Comfort:

• A lightweight and responsive sockliner sits on top of the bouncy Cushlon 3.0 foam for optimal cushioning for those rim-rattling verticals

Durability & Traction:

• The durable rubber outsole with a logo-inspired traction pattern grips the court like you own it so you can play fast and fearless
