There is nothing better than slipping out of your hiking, mountaineering, or ski boots and into a pair of lightweight Western Mountaineering Men's Flash Booties at the end of the day. These babies are packed with warm goose down insulation to help thaw out cold feet and give them some good ol' TLC. The Flash Bootie is primarily intended for use indoors, in your tent, or even in your sleeping bag, but a reinforced sole does allow for quick trip to the groover before bed.
