I bought like socks with grain filling for about 20 on a Christmas market a few years ago. As yesterday the Hot Sox came, I was disappointed. There are so few grains in the filling, which constantly trickle back and forth in these socks. My old grains socks are so full that little slip, even when lying down. I can also imagine that more grains better keep warm. So overall not buy recommendation. You also have to consider when converting (I had not paid attention), that product should be returned under 40 on their own account. Along with the delivery of the company was the whole thing an expensive business! Two stars there for it because the color is beautiful and the material fluffy.
