Thank you for looking. These are Tabio's 5-toe socks with an opening. The color is a beige-like shade. Recommended for yoga, Pilates, and the gym. They have anti-slip grips. The heel is open. I purchased them new and removed the tags, but they have been stored without ever being worn. I am also selling other colors, so please let me know in the comments if you would like to purchase them as a set.
