Slagbjørn Warm brings style and function to the coldest winter days. These boots are constructed from durable natural rubber which offers waterproofing and flexibility. Slagbjørn Warm is warm lined with a quick-drying polyester fleece, and a temperature-regulating insole that provides extra insulation and warmth. The shaft can be pulled shut to keep snow out and warmth in. Underneath, the non-marking high traction sole tackles slippery winter conditions with ease.
