Birks are getting downright architectural. Part of the brand’s elevated 1774 line, this collaboration with designer Thibo Denis takes the comfort-first philosophy of Birkenstock into considerably more experimental territory. The Uerzell has a sculptural, almost futuristic silhouette that feels somewhere between a traditional leather shoe and a piece of industrial design. There’s still a practical, everyday sensibility beneath the unusual proportions, which is what makes the whole thing work. Pair them with wide-leg trousers, a boxy jacket or some generously cut denim. They might not be for everyone, but sometimes the most interesting shoes are the ones that don’t fit neatly into any category.
