I think they are different sizes inside of one set , because some of them I wear really fast , but some of them are so tight , this is confusing and not the best feeling you know ! I prefer to have all the pairs of the same set with the same size! But design is well made

these are fantastic. only complaint is one had a small hole in the toe upon unpacking. but they are awesome and i dont care 1 pair wont last as long as the others. they are a little tight in the upper ankle area to get on, but not all pairs.a little inconsistent that aay.

Bought these as gifts for our math teachers this holiday season. They really liked them. A thinner sock, like a dress sock, but still good quality. Teachers appreciated them!
