When the Hot Sox arrived, I was absolutely thrilled - super fluffy and great visual impact. First disillusionment came when I tried on this. They sit very close. Both my feet (I wear 39/40) filled the shoes of very, and the Socks entry is quite scarce. However, it must be said that I also have strong sport conditioned calves and the shoe must keep anyway! My first wearing went super: The feet warmed up, the socks did not interfere on the sofa. I was very pleased (and am still). The next time you wear I had not so much fun, because at one of the socks, the seam was unlocked a piece and now that the first grains were way out of the shoe. But even as inexperienced seamstress I could see the seam fast reapieren and since then my Hot Sox enjoy.
