Summer is a great time to wear fun footwear like gladiator sandals, sky-high wedges and funky platforms. But what do you wear for the workday? If you want to be taken seriously, those options won’t do. Try these sophisticated shoes instead – Proenza Schouler Lace-Up Leather Slingback Sandals. They’re sort of a platform/gladiator/oxford shoe hybrid, but they’re ultra-classy and totally appropriate for work. Rich brown lizard-embossed thick leather straps crisscross to meet at a thin black ankle tie, with black stitching and contrast white canvas trim throughout. These Proenza Schouler shoes also feature a decorative laser-cut, net-like slingback strap and a 4½” stacked heel. The padded insole, lining and sole are all made of Italian leather.
