Luxury Birkenstocks are the new luxury sneakers. Recently Birkenstock finally released its highly anticipated collaboration with Dior, several pairs of racerback Tokio clogs (think the classic Boston closed-toe clog with a strap and a reinforced toe), and the Milano sandal that builds on the codes of the hippie-dippie Arizona shoe. Like the Dior Jordan 1, the resulting products not only resonate with the street-meets-luxury attitude that typifies Dior men’s artistic director Kim Jones’ career, but the sensibilities of Thibo Denis, the head of men’s footwear design at Dior.
