I wear 6 1/2 shoes, the small ones fit very well. There is an elastic band in the middle of the sock that keeps it in place, soft and comfortable. I'm actually giving 4.5 stars because I've never found a sock that was perfect for toe seams, I have an odd sensitivity to toe seams interfering with my baby toes and have yet to find the perfect sock but this is still the one best, albeit expensive, I order more, I like it very much, it is convenient to use.
