The Nike React Infinity Run Flyknit combines a sleek black and red design on a multi-layer Flyknit upper. A color-blocked no-sew overlay culminates in a Nike Swoosh, featuring a blue and red finish that matches the TPU piece that wraps around the heel. The React foam midsole utilizes a higher stack height and wider platform for added resilience and stability. Underfoot, a grippy black rubber outsole provides durable traction.
