These are so cute and colorful.  I've worn and washed these so I feel ready to review. First of all, I wear a size 6.5 shoe so I am always in a bit confused which size to buy when the "small" is for shoe sizes up to 6 and "medium" is for size 7 and above.  I ordered the mediums and am glad I did because there was some slight shrinkage when I washed them. . .not a lot but enough that I was glad I had chosen the roomier size.
