Lightweight and energetic, the Nike Air Winflo 9 are as good on your slower recovery runs as they are on tempo day. The translucent mesh upper feels extremely lightweight, getting air to feet, so they stay cool. The midsole has a whole new cushioning arrangement. Softer, springer foam combines with a full-length Nike Dot Weld Air unit for a more responsive sensation from heel to toe. The package is finished with a waffle inspired outsole, to deliver perfection traction for roads and footpaths.
