Before the Air Max 1, there was this: a prototype sneak that stayed on Nike's drawing board for thirty 30 years. Stepped up for ultimate breathability, these men's Air Max Zero Breathe trainers keep you cool in the heat. Made with a knit upper that keeps air flowing in and out, a cored out Phylon midsole reduces the weight without compromising on comfort or support. Equipped with the legendary Max Air unit to the heel for impact protection that's second to none, and a durable outsole keeps each step gripped with durable traction wherever you go.. Material: Textile & Synthetic Upper/Synthetic Sole
