I have poor circulation, so I wore these at night instead of exercising. They've stopped keeping me warm, so I'm selling all the ones I have. They're in various conditions. Two pairs show signs of wear. There's thinning of the fabric, stretching, puckering of the elastic, pilling, and fuzzing. Size: M I'm a size 23.5 and they felt large on me. [Product Description] Five-finger yoga socks to prevent cold feet. The toes and heels are exposed, and the non-slip grip on the balls of the feet provides 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, although they are a different size.
