Rated 2 out of 5 by from Omin heat socks I ordered four pairs of small after talking to a representative on the phone to verify this was my size. The socks arrived and run very small. The ankles are extremely tight. I will be trying to exchange them for larger size or returning them. There are only two small areas of Omni heat foil - not the entire length of the socks.
