Solid mid-cut safety boot with the best possible non-studded winter traction. Stable upper in durable and water resistant leather with rubber reinforcements. BUGdri® membrane keeps the feet dry and insulating 200 gram Thinsulate lining keeps them warm. Penetration resistant midsole uses composite material to block the cold from the ground and an insock with a laminated Alu-sheet reflects and keeps the heat generated by the foot.
