The brand releases a leather tennis shoe named after French player Robert Haillet. After Haillet’s retirement in 1971, the Haillet shoe is endorsed by US player Stan Smith and renamed. Throughout the ’70s, models carry a mixture of Haillet and Smith branding, before references to Haillet are finally removed in 1978. The Stan Smith goes on to become adidas’ biggest-selling sneaker, setting a Guinness World Record in 1988 with 22 million pairs sold.
