The Nike Ja 4 is starting to surface in more colorways, and this “Radar/Heat Check” pair is easily one of the busiest so far. Its upper looks like a thermal scan, with red, yellow, aqua, and blue bleeding across a deep purple base.

Bright orange covers the oversized Swooshes and the sharp support pieces running through the midsole. Those parts stand out immediately, but there is a lot happening elsewhere too. Black laces with orange trim sit over a black tongue, while the collar, outsole, and smaller sections around the shoe use the same dark finish.

The Ja 4 itself moves away from the softer shape of the Ja 3. It has a more angular build, heavily textured material, and larger pieces around the midfoot and heel. Morant’s branding appears on the tongues and underfoot, including repeated “12” markings across the orange sections of the outsole.
