Vintage Fur Boot

Vintage 1970's Apres Ski Boot Size 40 EU Size 9.5 US I believe from my research, these might be called Fimbul Shoes and are from Norway. They are also known as "Nutukas" Possibly made from Reineer or seal fur but I can't be sure about any of my research. These were given to me by my aunt and have been tucked away in a Rubbermaid bin for at least 30 years. Please look at all the photos for their used and vintage condition and if you have time, have a look at my other listings. Thanks and have a great day.
