I have tried several brands of grips socks. The grip wears off, my toes slip and my Pilates form suffers.
Since I have started use the barreletics grip shoes, those days are gone. I know have more confidence in my poses and the grip is consistent. Not to mention they are easy to put on and easy to wash. The mesh bag that they come in is very useful. It is big enough to hold my grip gloves for easy storing and transportation to class.
