I thought shearling is shearling. But RL thinks otherwise. Shearling in these boots means only the upper part on the inner boot (that comes out, by the way, to dry it) and the rest part of the inner boot is made of some artificial fabric. Considering the rubber lower part of the boot, it is not that warm, as expected.
I was looking fur natural fur winter boots that really keep feet warm in winter, and trusted the description which appeared to be untrue.
Quite frustrated.
