My Santa sent me these really awesome yoga socks that i've been wanting. I'm always slipping and sliding all over my mat and these socks are perfect for that. They have grips on the soles and I also have additional grip because my toes are out. They are made of super soft organic cotton too. What I like the best is that it has arch support. I have an EXTREMELY high arch which is painful if I don't have any support (Thanks to years of gymnastics and ballet!) So THANK YOU FRED! You are the best and I wish you a safe and happy holiday!
