Made from at least 20% recycled material by weight, the sock-like boot of this Nike Free is designed to transition from running to training to your everyday routine. With a breathable knit upper, it combines the flexibility you love with a secure design that will help keep you close to the ground for that barefoot feeling. New cushioning is lighter, softer and more responsive than previous versions so you can keep moving in comfort whether you’re on the pavement or track. Style: CZ1884-010
