most socks i see are marked either "one size fits all" or "fits shoe size 6 1/2 to 12." i wear a size 8 1/2 shoe and find that some of my socks fit well, while most of them are too big (the heel comes up to my ankle). the problem is, i don't recall what brand it is that fits me well, as they all look and feel pretty much the same. i know thomas pink offers small, medium, large, etc... does anyone know who else does this? i found socks at nordstrom selling for $25 that were marked one size fits all, which seems unacceptable at that price.
