Carbon fiber OD, the Air Jordan XXI, is a performance-oriented Air Jordan. After the lace-cover, shrouds, straps and leash, this “simple” Air Jordan designed by D’Wayne Edwards is a welcome relief. Easy to wear and it promises to be ultra-light weight. No more fiddly straps and lace covers to struggle with. But beneath its simple outward appearance is a whole host of high tech materials and production techniques to maximise support and comfort.
