The Nike Ja 4 Radar brings heat-map graphics to Ja Morant’s fourth signature basketball shoe. A dark Obsidian base gives the multicolor pattern room to stand out, with Total Orange branding adding a bright focal point along the side. Black laces and a low-cut collar balance the busy upper, creating a court-ready look that feels energetic from every angle. Beneath the graphics, the construction centers on support for quick changes of direction. A textured haptic overlay reinforces the lightweight foam upper, while the JA-frame wraps the midfoot to help keep the foot contained. Cushlon 3.0 foam works with a responsive SPRPWR sockliner to cushion landings and support an active game. A durable rubber outsole completes the setup with a traction pattern inspired by Ja’s logo. Traditional laces let you adjust the fit before stepping onto the floor. Whether paired with team shorts for a practice session or worn with relaxed athletic layers, Radar gives the Ja 4 a distinctive finish built around vivid color, sculpted support and a streamlined basketball silhouette.
