The mesh has a thin, flexible overlay that helps keep out water and makes it easy to clean your shoes. Underfoot Comfort A foam midsole and Max Air unit in the heel cushions every step. Versatile Grip An integrated traction pattern gives you exceptional grip in a variety of conditions. The new design draws its inspiration from the iconic Waffle outsole on the original Nike Air Max 90.
