Adidas Trefoil Liners Socks 3pk - White / Black A staple classic from adidas to finish off any outfit. Simple soft construction with trefoil logo detailing. Adidas was founded on 18 August, 1949 by Adolf Dassler, following a family feud at the Gebrüder Dassler Schuhfabrik company between him and his older brother Rudolf. Rudolf had earlier established Puma, which quickly became the business rival of Adidas. Both the Adidas and Puma companies still remain based in Herzogenaurach, Germany to this day.
