Whether they're for work or play, one thing is for certain: the Alpha Thermal keeps feet warm with 7mm of insulating neoprene and an extra plush fleece lining. Built for comfort and durability, these boots plow through snow, sleet, slush, ice and whatever else is in your wintery path. So when the mercury drops and the snow piles up, Jack Frost can nip all he wants at your nose, but he won't be touching your toes.
