Street Motorcycle Boots are boots that tend to have a shorter heel than other boots, in order to allow a motorcycle rider to keep control on the bike. Street Motorcycle Boots are generally made from heavy leather and may include metal, plastic and/or composite materials to protect the rider's feet, ankles and legs in case of an accident while riding.
