Working men have spoken! You don't want to worry about wet feet while you're on the job. The full grain leather 10" Justin pull-on is your kind of boot. It features a fully waterproof membrane lining and bio-mechanically comfort-correct orthotic Texon/Poron insole. A strong, but lightweight fiberglass shank won't conduct electricity. The non-marking polyurethane sole adds to your comfort - especially during wear on concrete. 1 1/8" heel. Goodyear welt.
