Have you ever heard of mukluks?  So, what are they?

Mukluks or Kamik are a soft boot traditionally made of reindeer skin or sealskin and were originally worn by Arctic aboriginals, including the Inuit and Yupik. The term mukluk is often used for any soft boot designed for cold weather and modern designs are often similar to high-top athletic shoes. The word "mukluk" is of Yupik origin, from maklak, the bearded seal, while "kamik" is an Inuit word. In the Inuipiaq language the "u" makes an "oo" sound, and so the spelling "maklak" is used with the same pronunciation.
