Question: What is the size to shoe size comparrison
Document: Bought this as a gift for a friend who wears a size 5 shoe. She could never find yoga socks that fit and didn't make her slip. She loved the socks and wears them several times during the week when we take our yoga class together. Super fast delivery also.
I own these ToeSox half toes in the purple stripe and solid red. They're great for Pure Barre and Bar Method classes. I haven't used them for yoga but I'm sure they're great for that too.I wear a size 5 shoe and the Smalls fit me very well.
These are perfect for pilates and yoga. The small fit was exact (I wear a 7.5 shoe). I bought these for a friend as well in a medium (she wears a size 9 shoe) and they fit her perfectly as well.I have purchased 3 pairs of these so far. I would recommend air drying them after washing to preserve the "stickyness" of the bumps on the bottom of the socks.
I really like the quality of these and they fit well. It's like having the grip of a running shoe with the comfort of a sock.
My friend love these socks, they were so comfy and perfect for Yoga. The are also true to size. Thanks!
I love these. Keeps me from slipping. And its sanitary. And true to size. I use them for Pilates. :-)
These fit me perfectly, and I have small feet - size 5 if I am lucky. It works great and stops me slipping during Yoga :-)
I bought these and fell in love with them. Its hard to find toe-less toe socks in my size but these managed it. I recommend them.
Comfy socks not too tight on the toes nice grip  durable. True to size. Wash well in the machine and hold their shape
I tried out the socks in my yoga class. Half way through I had to rip them off. they were very uncomfortable and digging into the spaces between my toes. I don't think it was the size but the dessign. did not like them
Answer: no
