Created to provide a barefoot-like running experience, the Nike Free 4.0 is a neutral road sneaker optimized for competitions. This edition features a Volt mesh partial bootie clad in contrast, fused overlays for durability and structure. Neon laces lock the padded tongue in place. Its flexible underfoot is shaped by siped Phylite midsole cushioning equipped with rubber nods at the forefoot and heel for grip control.
