 yoga toes was a popular brand i think they're too big and too bulky so i use a brand called mind body that you can get on it's b-o-d-h-i that you can get on amazon and i have people put these spacers in so it looks like you're getting a pedicure but maybe a little bit more so and i have people put them between their toes and squeeze from side to side not curl their toes up and down but squeeze from side to side because that actually activates the muscles in the arch
