Flashback to the ’70s. An era of bold creativity and self expression. Also, the era in which the adidas Trefoil and the Stan Smith shoe were first unveiled. Going full-on vintage, these shoes celebrate both. Their classic design looks just as low-key as ever, while patchwork Trefoils burst with color. Even with the old-school vibe, this pair is focused on the future. They’re designed to create less material waste.This product is made with Primegreen, a series of high-performance recycled materials. 50% of the upper is recycled content. No virgin polyester.
