The new Meindl Workman Lineman Men's Safety Toe Leather Work Boots by Hoffman's is a new boot that has some very unique features. Built with FR Fabric in the upper, the Workman has been tested to help protect against an unforeseen arc flash or other exposure to flame. The breathable fabric lets more air flow through the upper to help keep you cooler in the summer. A waterproof membrane helps keep you dry and Hoffman's Dual Steel Shank System provides the support that other climbing boots are envious of. Cushion insoles, FR laces, solid hardware and a sturdy, rebuildable Vibram sole make this boot a must have.
