Men's PHG Omni-Heat™ Boot Sock 3.7 5 3 3
OK Thin and light, not really a cold weather sock. The Omni heat technology does not add any warmth. Sizing is tight as with every Columbia product. January 21, 2012
Feet warm I bought these for my father and he loves them. Wears them to knock around the house, to work, and even dressy sometimes (if my mom let's him get away with it) :) He has diabetes and when wearing them around the house, he thinks they really keep his feet warm. Thank you Columbia. December 19, 2011
Omni socks The socks fit and construction seem flawless. I wore at 20 degrees and my feet stayed very comfortable while moving. While sitting for long periods, my feet did get cool. If I'm moving, I'll use them cause they are comfortable. If I'm sitting for long periods, I believe I'll use layers of merino. November 8, 2011
