The upper material made of nubuck leather is particularly robust. Thanks to the surrounding high rubber coating, the boots are well protected against penetrating water. The Alborgplus feature a removable inner shoe made of 3M Thinsulate material, which keeps the feet pleasantly warm. Additionally, this design makes the boots easier to dry, air out, and clean. The thick, profiled, and waterproof outsole ensures a secure and slip-resistant grip. With the generous lacing, the Alborgplus can be comfortably put on and taken off, and the inner shoe is easy to remove and insert.
