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 50°C. A Vibram rubber outsole helps to avoid any kind of slip and your feet are protected with these railway safety boots by a composite plate and toecap. A PU shell around your foot makes these offshore boots nearly undestroyable.
