Adidas TRX Originally released in the late 70's, the Adidas TRX is back. Plus, Adidas is now releasing them in new fresh colors with "never seen before" materials. The Adidas TRX features lightweight construction with a flared sole and classic rubber nubs for traction. At the time of their debut, they were considered the top running sneaker on the market. Although they are still extremely comfortable, today you're more likely to see them walking down a city street than running around a track.
