Originally designed for performance running, the low-profile Tuned Air units in the heel and forefoot create a haven for your feet with lightweight cushioning that responds to every step. Sleek, track-inspired upper is made with durable synthetic materials for a lightweight, breathable feel. Plush foam midsole features flowing lines that add energy to every outfit. Stretchy, bootie-inspired tongue wraps your foot for a personalized feel. Launched in 1999, the Nike Alpha Project fused cutting-edge technology with exciting personality-driven design. The 5 dots on the tongue and heel are a symbol against mediocrity and pay tribute to the Alpha Project's best-in-class performance and comfort.
