Reebok International feels comfortable stepping out onto any surface. The company, a subsidiary of Germany's adidas AG, has long been at home in sporting arenas as a top US maker of athletic shoes. In addition to its namesake sportswear and accessories, Reebok caters to hockey aficionados through its Canadian Reebok-CCM Hockey division, and its Sports Licensed Division. It operates more than 220 retail stores. Reebok, which has been credited with igniting the aerobics craze of the early 1980s, has fallen out of step since then. Under adidas, the company is trying to regain traction in the athletic shoe and apparel market.
