These were suppose be no Slip, but these socks did not prevent that.

Soft, flexible, helps to feel stable and provide coverage when practicing in unconventional spaces (yoga events, etc)

I don't think these prevent slipping. I haven't found a pose where they help. Maybe they would make a difference if you were doing this on a truly awful, slippery surface, idk. From my trials, doing strength yoga flows as well as long, slow stretches, it seems like I need grippy gloves more than grippy socks.

They fit a hair small but otherwise are super durable. Way softer than they look.

I hated these socks so much that I threw them out right after barre. They are thin, in padded and don’t stay on your toes. They distracted me during class and I couldn’t enjoy my workout. Don’t waste your money!

I prefer wearing socks during yoga. These stay put, no slipping.

[...]YOGA, is an absolute pattern of science which helps you build yourself mentally & physically. Most of the postures in Yoga teach you the act & art of balancing your body. The stretch - really important to rejuvenate the blood circulation all over your body to tone each and every muscle and ligament, needs a firm base to practice this posture on. [...] Now concentrate on your postures as you exercise the art of YOGA without having mental barriers of im-balance & accidental occurrences. The grippers located on the sole of the sock create friction between the Feet and the Floor enabling you to reach the high definition of exercise through yoga.This product has been the best since I have used it. Now I can really enjoy the true essence of exercise. I would encourage all the YOGA participants to get into these socks and never to worry to carry an additional bag with your YOGA mats in it.

I am a newbie to yoga, and love it, but am prone to nasty foot cramps when my feet get cold. These Gaiam Gripping Nonslip Yoga Socks did the trick for me--keep my feet warm enough to avoid cramping, and gripped the floor/mat just like bare feet. I anticipate they will launder in cold water fine with my other washables, but will let you know if they do not. To date, I am very satisfied with how this product performed, the price is decent, and I will recommend them to others. Thank you.
