One of the biggest names in sportswear today, adidas has humble beginnings. In 1924, German-born founder Adi Dassler launched his footwear brand out of his mother's laundry room. After attracting a few Olympian gold medalists, however, the label became a global phenomenon. Today, the athletic wear juggernaut does it all, from high-tech workout clothing and cult-favorite adidas sneakers, like the famed Stan Smiths, to high-fashion collaborations with Raf Simons and Stella McCartney.
