The Viking spiked forester boot is the top of the line boot for lumber and timber work. It's made from sbr blended nr rubber with a polyester lining. These boots have a reinforced heel and instep. Can be used for forestry, surveying and roofing. Viking boots are different from other boots because we focus on safety, not as a guide - but as a philosophy, making sure every boot we produce exceeds the standards and embraces comfort and wellness for the wearer. We work with miners, foresters, fishermen and firemen to understand their comfort issues and bring their responses to market in our boots. Shaft measures approximately 11" from arch.
