Men, if you’re going to insist on wearing sandals this summer, please don’t call them mandals and please make sure your talons are clipped and/or filed down. And when it comes to choosing a style, please keep it simple. Jil Sander has a low strappy leather number in pure-energy yellow (around $600), while Acne goes even simpler with what amounts to a toe-flossing flip-flop ($315). Maison Martin Margiela found salvation in an artisanal Jesus-like style ($420), and Bernhard Willhelm has again teamed up with Camper on a hazmat-inspired Velcro option ($175). Any of these would make a fine choice, and they’re all available at Oki-Ni.
