The Air Jordan 4 featured many new design concepts. First, the straps on the side for increased ankle support. It was nearly impossible for MJ to roll his ankle in these shoes. The Air Jordan 4 again featured the air sole heel for dded cushioning and a full length midsole. The foam insole offers a lot of softness to the shoes. Characterized with the Nike Air unit, the midsole makes the  Air Jordan 4 shoes become extremely cushioning.
