Monks can be divided into two categories; Single and Double Monks. Whether the shoe is categorised as a single or double depends on the number of straps used to buckle the shoe. The modern monk model takes its inspiration from a specific type of shoe that monks used to wear during the Middle Ages, over 700 years ago.
The monks can best be described as a semi-formal shoe. It works equally good with jeans and an unconstructed jacket for a smart casual look as to dress down a suit for a less formal look.
