If you don't go for the gold, you'll never stand on the podium. The SL 72 made its debut on the world stage in 1972 and was the first adidas style to sport the Trefoil. These shoes stay true to the legacy with an authentic shape and materials. The toe box fits slightly narrow, just like the '70s version. An EVA midsole cushions, and the rubber outsole features a vintage-era traction dynamics system.
