The Nyjah 4 still prioritizes a flexible fit, strong grip and responsive cushioning. Stepping away from its predecessor, this design features a classic tongue structure and an updated traction pattern that feels like a Nyjah signature. Reinforced mesh in the upper allows breathability. Air Zoom cushioning helps provide a quick-off-the-ground sensation. Durable plastic clip helps improve heel containment. HART (High Abrasion Rubber Tech) outsole uses less rubber compound than our other XDR rubber technologies—without sacrificing durability and abrasion resistance. Less material helps make the outsole lighter and more flexible. FQ1273-003
