Men's Nike Air Zoom Structure 21 Running Shoes Black / Anthracite / White

For two decades, the Nike Air Zoom Structure line has delivered trusted support, speed, and style to overpronators. The Nike Air Zoom Structure 21 is no different. This stability running shoe helps guide you to a more efficient stride with a dual-density midsole construction that places firm Phylon foam on the medial side of the shoe and softer Cushlon on the lateral side, combining stable support and cushioned comfort that helps correct your stride without sacrificing a soft feel. An engineered mesh upper with inner bootie hugs the foot without restricting movement, delivering a secure fit you can count on, mile after mile.
