SKINS Women's Active Compression Sock

I've worn these once but they felt so good I immediately bought a second pair while they were at such a great price. I looked at a bunch of pairs on amazon and was intimidated by the lack of sizing and M/F info, but they fit well and seem very solidly constructed. I'm a woman and wear a size 9.5 shoe usually. I've got average sized calfs. I ordered the medium size in purple and they fit great. Compression, but not cutting off my circulation. I will say I wish they were a half inch shorter, because when I sit they hit right where my knee bends. These are going to become a regular part of my running gear.
