Sievi thermo boots

Solid XL + S3 is a warm woodpecker for cold conditions. The safety tip and nail guard are made of steel. The upper is made of wear-resistant and water-repellent leather and the tip is protected by a tip cup. The villated duo lining keeps your feet warm. The FlexStep® elastic sole gives the footwear excellent shock absorption and the firm sole pattern improves friction properties. Zipper and straps make it easy to put on. The removable Thermo Alu thermal insole adds extra insulation to the footwear: the heat-insulating aluminum layer reflects cold outside and heat inwards. The footwear is antistatic and also meets ESD requirements. Spacious XL last.
