Boat shoes, commonly known as deck shoes, is a generic category used to describe a particular style of shoe that is popular to wear on boats and docks. The majority of boat shoes are constructed out of oil treated leather to repel water and have a skid resistant rubber soul designed to help the wearer grip the floor even in wet conditions.
The modern boat shoe was created in 1935 by Paul Sperry. His inspiration came from observing his dog's ability to run over ice with a great degree of agility. Upon examination of his dog’s paws he made the connection that the textured surface of the foot pads increased grip and reduced slippage. Using this observation he carved a non slip pattern into the bottom of his shoes; and the rest is history.
Today it is still popular to wear boat shoes on boats; however they are also a popular fashion choice in many western countries for day to day casual wear.
