The Nike Air Force 1 UltraForce Mid Women's Shoe features a breathable inner-sleeve, ultralight cushioning, and reflective accents that elevate the classic. Breathability An inner-sleeve made from breathable mesh keeps air flowing. And it helps you get the shoe on and off easily and comfortably. The Lightest AF-1 The durable foam midsole is cored out in key areas for an incredibly lightweight, flexible feel. It doubles as an outsole, dramatically reducing the shoe's overall weight—making it the lightest Air Force 1 yet.
