Thank you for viewing. These are Tabio's five-finger hole socks. They have a gray-like color. Recommended for yoga, Pilates, and the gym. They have non-slip grips. The heels are open. I bought them new and removed the tags, but I have never worn them and have kept them in storage. I am also selling other colors, so if you would like to purchase a set, please let me know in the comments.
