Inspired by the Air Max 720, the Nike Air Max FF 720 takes a classic sneaker and turns it into a closed-toe sandal. It features a bubble sole that cushions the foot and adds height to the silhouette. Instead of the traditional crossed laces, the Nike Air Max FF 720 offers a simple loop that's easy to adjust. The Nike Air Max FF 720 released in June of 2019 and retailed for $250.
