The Sorel Men's Glacier XT Boot is a snow boot for extreme winters. Outdoorsmen that spend their time hunting, ice fishing, and more need a warm boot that will stand up to the challenge. The waterproof vulcanized rubber shell gives the burliness you need to tromp through cold snow, mud, slush, ice and more. At the upper is water and wind resistant, PU coated synthetic textile to protect the lower leg, with a barrel lock closure to seal out drafts and snow from entering the boot. A short lace secures the foot in the boot at the instep so you won't loose your boot while moving through deep snow. Inside is where it's at, keeping your toes and feet warm and toasty is a removable, 13mm, ThermoPlus felt inner boot with Omni-Heat™ reflective lining. Like a personal oven for your feet.
