RxBshoes brings us a '60s-inspired take on their signature mule, which they've updated with a strap across the instep for double the fun. We love the black and white op-art print, which is a fabulous look with jeans, leggings or your own op-art creation. They've been handcrafted in St. Petersburg, Russia, with attention to every detail, and represent one of RxBshoes' most modern looks of the season. In black/white. Made in Russia.
