In the land of dad shoes and over-embellishements there's Margiela.  The Tabi Brushed-Leather Shoe is a nice clean walk into the idea of the tabi.  Characterized by the split toe construction originating with Japanese Special Forces in the early 1900s, the tabi may make you think of a hoof but just think more like an ergonomic barefoot shoe meets a pair of flip-flops in the separation of the big toe from the rest of the toes.  The result is not discomfort but simple coziness and, with this model, the comfort comes in the buttery leather outer, smooth leather lining and collapsible heel feature.  It's all simple and clean and plausible with loose trousers, cropped or long, or even with modern joggers.  Available now at LuisAviaRoma.com.
