Originally debuting in 1996, this iconic piece of footwear compiled the data from hundreds of athletes to create a revolutionary fit that follows the natural curves of the human foot. This revamped offering features a black leather upper complete with python-like detailing, broken up by woven stitching throughout that not only allows for a more natural fit but cuts down on glue usage too. Layered underfoot we find a full-length foam midsole with an Air unit in the heel before a waffled rubber outsole completes the look.
