Portugese menswear and online shop Por Vocação has slowly developed a relationship with shoemaker Buttero over the years. The first collaboration between the Italian brand and the Porto-based shop takes the form of the Derby Shoe. Often suggested as a step down in formality from an oxford-style shoe, the derby shoe comes in three black, dark brown and taupe colorways. Handcrafted in Italy and featuring premium vegetable-tanned horse leather, the rubber outsole with protective anti-slip rubber adds a modern touch to this vintage-looking design. Exclusively available from Por Vocação in-store and online.
