These socks are the most comfortable socks I own! I have rather large feet. (size 9.5-10 in women's) and I don't feel a seam and they don't feel thin anywhere around the sock. Sticking your foot in here was like surrounding your foot with a cloud. My only complaint is that I don't wear many red or orange clothes so the color pack I bought wasn't the greatest for me. However I will be buying more in the near future in other colors.
