Hand knitted wool slippers which the maker calls socks.  

European size 37 - American size 7-8 in women's

Description from the maker:

"Socks are knitted from natural Slovenian sheep wool. They are lined with clothing leather. Socks are suitable for warming your feet and do not replace the slippers, even if you take a few steps in them. They are made so that they can be worn in different leg sizes.  They can be washed at 30 degrees, but it is best to wash them manually."
