Bring out the tube tops and rhinestones, these adidas Astir Shoes are all about the extravagance of the 2000s. The foundation is built off of a running silhouette, but the pops of colours and graphics sprinkled throughout can almost distract you from that fact. We did say almost, though, because there's no mistaking the dynamic lines and performance-inspired outsole, no matter how much attitude is layered on top.
