The Air Max Pre-Day is back in triumphant fashion with this explosive smorgasbord of color. The upper is a mixture of materials made from recycled polyester and leather textures, with hits of leather at the toe-box, swoosh, and heel. A blue leather cage keeps the laces in check along the tongue, which features a retro Nike logo on the tongue tag. The center of the midsole has been hollowed out to show off the Air Unit, which rests on a waffle-like, Nike Grind rubber outsole, made entirely from recycled materials. So it’s a shoe you can look good in, while feeling good too.
