The plain Derby is exactly the right model for purists who want to keep it simple but also do not want to do without versatility. This is a classic equipped with the best we have to offer. On the one hand, it is the leather that provides the silky shine of this shoe. This can be credited to the fine leather that adorns the upper and is characterized by its soft yet also hard-wearing nature. The French calfskin leather gets its soft feel from its tanning, which is predominantly vegetable based.
