Moose, beluga whale, wolf, wolverine, muskrat, squirrel, fox, polar bear, eider duck skins are also used, however. Seal skin is water-resistant, which is an important factor in the warmer, wetter seasons, and caribou skin, which is coated in thick fur, is excellent in dry, extremely cold weather. In seasons where the weather is in-between, boots with seal skin soles and caribou leg portions are ideal. When making boots, the first consideration is climate. Contrary to popular belief, the Arctic is not always a snow-covered tundra.
Summers can be warm and wet, and winters cold and dry.
Consequently different boots are made to suit different occasions and climates.
