In the late 60s adidas expanded into the leisure and apparel sector, and this prompted [adsense]
Kathe and Adi Dassler to seek a new, additional identification mark for the adidas
brand. In August 1971, the Trefoil was born, out of more than 100 ideas. Inspired by
the 3-Stripes, it is a geometric execution with a triple intersection, symbolizing the
diversity of the adidas brand. This symbol was first used on adidas products in 1972,
and later became the company’s corporate symbol. Today it plays the important role
of representing the adidas Originals collection.
