Have this Hotsox bought for my friend, because he always has Eisfüße. He has size 44-45 but in these slippers, he adapted very very scarce. I (size 40) fit perfectly pure. Functionally, they were good. Unfortunately came after a few uses at the sides already out the contents, which can of course be because they are too small. Think it is quite unfortunate that the specified size so different from the reality.
