Klim Mammoth Socks 5 5 4 4
STAY COSY THIS WINTER IN THESE INCREDIBLY WARM FEATS OF FABRIC ENGINEERING Thanks to the Terry construction, the Klim Mammoth socks are likely the warmest socks available on the market. Luxuriously thick, they are great when worn with Gore-Tex boots (or without for that matter) to wick away the moisture, however, are just as much a godsend when your feet are particularly nesh like mine, suffering from the cold when temperatures drop. I don’t care where I am, how stunning the scenery is—if the cold starts to burrow through my feet like a worm, then I can’t concentrate on much else. Blocks of ice for feet are about as much fun as a funeral. Stay cosy this winter in these incredibly warm feats of fabric engineering. January 16, 2016
Very very warm The fit is great, very soft, very thick, very warm,very comfortable to wear all day in steel toed boots and my riding boots, I would buy this product again ! April 5, 2015
Excellent warm sock, runs large These are nice, thick, comfortable, WARM socks. If you're riding in cold weather and have a little room to spare inside your boots, you won't regret getting these. For sizing, guidance shown on other web sites is SM = 4-6, MD = 7-10, LG = 11-14. However, I'm a 6-ft 240-lb gentleman with shoe size 11, and I found the Medium fits me with room to spare. They pull up to just below the knee, and would probably fit a size 12 foot just fine. December 8, 2014
Great Thick Socks These socks are very thick and warm. Riding in 70 degree weather was not too warm. Riding in 40 degree was not too cold. October 28, 2014
