"The legendary Expedition Booties have been reimagined in Gore’s highly breathable and totally windproof Infinium Windstopper. Multiple layers of cozy Primaloft insulation wrap your feet and ankles, helping you feel recharged and ready to get after it again tomorrow. At the end of hard day out on ice, snow or rock, these booties are as welcome as a hot drink and a soft seat. Grippy bottoms and water-resistant-breathable shells keep you sure-footed and dry if you need to cross snow on the way to the outhouse."
