Nike Winflo CW3419-002 Mens Running Shoes (Black/DK Smoke Grey-Smoke Grey) - When running is an everyday habit, you need support to match your speed. The Nike Winflo 8 brings back the cushioning you love and pairs it with details like a translucent upper and Flywire technology for a snug, stability fit for long runs. Lightweight, Breathable Support The upper uses translucent mesh and perforations at the forefoot for breathable comfort. The Flywire cables work with the laces to provide more support as you tighten them. Cushioning For Your Miles Zoom Air units in the forefoot and heel put cushioning where you need it. Cushlon foam makes it soft and responsive and puts more springiness in your step. Comfort Where It Counts Foam around the heel and ankle combines with support at the base of the heel for a secure fit. More Benefits Overlays at the toe add a layer of durability. The tongue is connected to the upper's inner lining for a secure feel.
