Boat Shoes are shoes designed for yachting and sailing activities. Boat Shoes have soft soles and heels to avoid marring or scratching a boat deck. Boat Shoes are two to three eyelet oxfords, often with lacing woven around the heel with a moccasin-like look. Boat Shoes are also commonly referred to as Deck Shoes.
