Booties are small, sock-like coverings made from durable yet breathable fabric — commonly polar fleece, Cordura nylon, or a blend — that are placed over a sled dog’s paws and secured with a Velcro strap around the wrist. They are one of the most essential pieces of equipment in sled dog racing and winter dog sports.
Their primary purpose is to protect paw pads from abrasion on hard-packed snow, gravel sections, and glare ice. They also prevent ice balls from forming between a dog’s toes, which can cause pain and lameness if left unchecked. In longer races, mushers may go through hundreds of booties as they are checked and replaced at every stop.
Fit is important — a bootie that is too loose will fall off on the trail, while one that is too tight can restrict circulation. Experienced mushers learn to put booties on quickly and check them regularly during runs.
