Adidas ZX 500Originally released in 1986, the Adidas ZX 500 was touted for its performance capabilities. It was designed to be a comfortable high-mileage trail and running sneaker. And because of its TPU heel counter, it boasts superior motion control for the wearer while on the road or trail. This attractive model features a synthetic upper with a detailed graphic design. The earth tone colorway is subtle and allows this model to be a very versatile sneaker.
