I bought these because, although I'm a woman with small feet and they don't fit very well, my rental house has very little insulation and it's been freezing here in Louisiana (who woulda thought)?  Anyway, they are very warm and cover my entire calf, so I'm happy with them.  I would have liked if they were less scratchy, but they aren't as scratchy as pure wool socks and are just as warm.  I wear them nearly every day around the house and am glad I made the purchase.  Which, btw, was very economical for the price since there were four socks included in the package.  That's the reason I chose these, instead of others that fit better.
