The 10" Steel Toe Dri-Line was built to keep your feet dry when conditions are wet. A highly advanced Sympatec waterproof membrane keeps water out and adds cusion and comfort to the boot. For climbing, our dual steel shanks are added to provide the extra arch support needed. Other quality features include a 7-7 1/2 oil tanned leather upper that provides support to your legs. A climbing side patch, solid brass hooks and eyelets, supportive heel counter, vibram lug soles and three rows of durable stitching help prolong the life of the boot. The 10" Steel Toe Hoffman Dri-Line is both EH and ASTM F-2413-11 MI/75 C/75 approved. For those looking for a quality waterproof climbing boot, look no further.
