The Nike Air Winflo 9 has a secure fit that keeps your foot in place as the miles go by. We added plenty of foam through the midsole, giving you extra pep to every step. Lace up, lock in, win your goals. Lightweight, Breathable Support The upper uses translucent mesh for breathable comfort. An inner midfoot strap works with the laces to provide more support as you tighten them. Energized Steps Soft foam has been updated from the Winflo 8, giving you a springier feel that adds bounce to your stride. We used a full-length Nike Dot Weld Air unit for added support and responsiveness from heel to toe. Feet to the Ground A rubber outsole with a Waffle-inspired pattern provides road-ready traction.
