The Hot Sox have convinced me of the price-performance ratio. Already the fleece-like upper is nice and comfortable and my feet also were still warm after the grains were cooled. The shoes are behind not openly, but put the entire walk right up to the ankle thanks to elastic waistband. To walk around the shoes - as mentioned on the packaging - not suitable, but I found them both sitting as well as comfortable to wear while lying down. You should just be careful that the grains are evenly distributed at Slip and not form a lump in one place. In addition, I advise the purchase to grab the larger size, even if most colors unfortunately only in size M are available, because the shoes to be relatively small. I have shoes size 40-41 and have resorted to size L, because I was with my shoe size between M and L. The shoes in L (Gr.41-45) sit comfortably, but because my feet already quite filling, I could imagine that M turn out for size 39-40 shoe carrier and L for shoe size 44-45 to support small and the elastic waistband around the ankle possibly sits too tight.
