Ja 4 'Dark Mode'

£119.99

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 of "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.

"Dark Mode"

Ja's relentless work ethic happens behind the scenes. This black and metallic silver colourway celebrates the moments in the gym when it's time to lock in on your craft to be the best.

  • A pleasant surprise of a hoop shoe

    drg4177

    When I first looked at the shoes after opening the box, I had a feeling they would be heavy based on looks alone. And after initially putting them on, I felt that same feeling. But after moving around with them and getting some shots up, I was pleasantly surprised at how smooth they felt! They didn’t feel as heavy as I thought and the support of the shoe felt strong. Jumping and running feels normal. I had always been intrigued by Ja shoes, and this model is honestly a great pair to own. The materials are superb, this specific black colorway looks fantastic, and the comfort level is good, although not as comfortable as some other hoop shoes I own, such as many models of the Lukas. It’s not a perfect shoe but it’s a quality pair to play in. I would definitely recommend!

    These Nike Ja 4 Dark Mode shoes are pretty cool. My uncle got them for me and I’ve been wearing them to play basketball. The color is mostly black with some shiny silver and a little blue. It looks sneaky, like dark mode on a phone. Not too bright or crazy, just clean. I like that. They grip the floor really good when I run and cut. My feet feel locked in and they don’t slide around. The cushion feels nice when I jump and land. They’re not super soft like pillows, but they do the job and don’t hurt my feet after playing. The build feels strong, like Nike usually does. Nothing cheap or falling apart after a few games. Fit is good for me once I wore them a couple times. Overall I like them a lot. They’re solid for basketball and look good too.

    The sneakers are suprisingly waterproof, I got caught in a heavy downpour kept my feet dry. Grip was excellent as well. Got rained out so didn't get chance to test them on the court but I did end do a but a walking and they were very comfortable. The arch support for me was everything I needed. Very comfortable for standing a good period of time. Dope color way.
