The Russian ethnicity's "yudaike" boots are made from horse skin, while special shoes are made from mustang skin that is dyed red. The Hezhen have always been a fishing community. They use the skins of the huaitou fish, zheluo fish and pike in manufacturing fish-skin boots. The boot-leg is usually 30 cm long. Lined with grass and tied to theleg with fish-skin straps, the boot is especially comfortable and warm. Tibetan boots are usually made from horse skin or yak skin, the sole is hard but the upper is soft. The boots have a layer of woolen fabric in them and there is a 10 cm long slit at the back of the boot which makes wearing and removing the boot easier. The style of the boots is rustic but designed for maximum comfort.
