The Nike Ja 4 ‘Radar’, also called the Heat Check, just dropped October 25 for $140, and it is the most conceptually fun Ja 4 yet. The nickname comes from the thermal-style print across the upper, a heat-map pattern that plays on Ja’s reputation for catching fire during games. When he gets hot, he is literally glowing, and now the shoe does too.
The look is an Obsidian base with Total Orange and Laser Orange accents through the thermal print, plus Racer Blue and Cobalt Bliss hits keeping the palette from being purely autumn. The haptic textured overlay that defines the Ja 4 carries the print well. It is a busy shoe, but the color story gives the busyness a purpose, which is more than I can say for most loud colorways.
The launch timing makes it the signature sneaker story of the young NBA season. Ja’s line has become Nike’s best-selling performance signature not named Sabrina or LeBron, and the Radar colorway got official photos and a full SNKRS rollout. The GOAT page shows the Radar with its full October release details.
Market check, StockX has the Radar asking around $147, basically retail. The volume Ja 4 colorways have all settled near retail, which means zero buying stress. If you want a wearable piece of the Ja Morant moment without paying resale, this is your window.
The Ja 4 platform itself continues to be the performance bargain of the signature market, a $130 to $140 shoe with Air Zoom forefoot cushioning, a snug haptic-mesh fit, and Ja’s highlight-reel energy baked into every colorway. The Radar is the one people will remember from this season, like the Nightmare was for the launch.
It is live now through SNKRS and retail. If you only grab one Ja 4, make it this one. The thermal concept is the best colorway idea Nike’s basketball line has shipped all year.
