In Europe — in some countries, especially in the eastern Europe there are very common shoes which covered inside with something that makes it warm and comfortable in the time of the winter, cold and snow. What is the general name for this inner cover?
(I have tried to find the term in my language and I didn't find. I also looked for it on a visual dictionary and no results. I'm even not sure if the using of the word "cover" is correct in this context, but that's the way that I can express myself)
Can I call it: upholstery?
(This knowledge can be useful for example when going to a shoe shop and I would like to ask for such shoes and how to name them correctly and understandably)
