adidas GX1021 More than just a couple of hoops and concrete. The basketball court is a meeting place — a place to trade ideas, passions and points of view. Keep that vibe alive in your everyday life in these adidas Forum Mid Shoes. Based on the classic style from '84, this version keeps it real with a clean leather and suede upper and a recognizable X design. The iconic ankle strap lets you honor decades of basketball greats every time you step out.
