I used to wear these to bed because I get cold easily. However, they're not keeping me warm anymore, so I'm selling all the pairs I have. They're in various conditions. Two pairs have signs of use. They're in relatively good condition, but there's some stretching of the elastic and some pilling. Size: M? They seemed large when I compared them, so I think they're M. 【Product Description】 Yoga socks with five toes to prevent cold feet. The toes and heels are exposed, and the non-slip processing on the ball of the foot maintains grip. They come in a mix of colors that are easy to coordinate, and they use moisture-absorbing and heat-generating yarn for excellent warmth. I'm also selling a total of six pairs of Suria Caldo Ketta socks, which are a different size.
