adidas Slip them on and go off. Shaking up a classic, these adidas mules honor the iconic Stan Smith shoes in a way you never knew you needed. The clean upper and heel cap detail are inspired by the original, but the chunky proportions and ultra-smooth feel revolutionize with a modern twist. They're built with a foam material that's made in part from sugarcane for eco-minded design you'll be proud to rock. No straps or laces means they slip on and off — but stay comfortably on your feet the entire wear. These shoes are made with natural and renewable materials as part of our journey to design out finite resources and help end plastic waste.
