Designed to support you in the toughest environments. While quick access to the boots is supported by a BOA closure system Helly Tech® and Primaloft® will keep you dry and warm down to minus 40°C. A Vibram rubber outsole helps to avoid any kind of slip and your feet are protected by a composite plate and toecap. A PU shell around your foot makes these boots nearly undestroyable. For outstanding comfort over a long time this boot features a dri blaze lining and an ortholite sockliner.
