These boots are brand new still in box. They are a Mens size 10. These boots are awesome! They are meant to keep your feet warm in temperatures as cold as -25 degrees fahrenheit! They are extremely light, have a removable liner for when you are inside, a waterproof shell, and 250 grams of 3M Thinsulate Platinum Insulation. These boots are originally priced at $150.00, but I am open to negotiation so start making some offers!
