Enough rapide for your daily runs, light enough to keep you going. The Nike Air Winflo 9 offers a secure fit that keeps your foot in place throughout your run. Slip it on, tighten the laces and pulverize your goals. The upper is made of a clear mesh with perforations in the forefoot for maximum breathability. Flywire cables are integrated into the laces for added support when you tighten them. The Cushlon foam in the 8 has been redesigned to give you an optimized bounce in your stride. The waffle patterned rubber outsole provides road-friendly traction. Padding in the collar provides a snug, secure fit.
