I Love these sock by Inversion Studios of course they are for Yoga & Pilates. And I'm sure they would work fantastic for those activities but I don't do those activities I got the socks to wear around the house and I love them they are soft and they fit like a glove so they keep my toes toasty warm and they stay put with the straps across the top and the non-slip tread on the bottom they are very comfortable. I washed them with my regular white clothes & they came out just as they were new, no shrinkage. The Material:75% Cotton | 23% Spandex | 2% Elastane.
