The Nike Air Force 1 Crater Flyknit updates classic b-ball style with at least 20% recycled content. Super-airy Flyknit material feels breathable and stretchy around your foot. The speckled sole ups the legendary comfy style that lets you give a little back with every step. Nike Flyknit technology uses strong (yet lightweight) yarns to create fabric that's supportive, stretchy and breathable. Crater foam cushioning, made from a spacey mix of about 12% Nike Grind, feels lightweight and responsive. The hidden Air-Sole unit is designed just the same as the '82 original. The Swoosh design, heel and around the laces contain some recycled material.
