This work boot provides it all: safety, comfort and durability. Crafted in full grain leather, this boot features a ASTM-certified steel toe for maximum protection against unforeseen hazards. Plus, steel toe is covered by Tough Tech leather for superior abrasion resistance. Heel impact zone cushions against impact and fuels momentum. Polyurethane midsole absorbs impact for the entire foot. Steel shank provides stability and protects arches from potential injuries on hard surfaces. The Caterpillar SRX S-curve outsole design provides maximum ground contact, slip-resistance and easy movement, as well as protection from electrical hazards. Outsole flex grooves before and after metatarsal heads act as a hinge, allowing the boot to bend and flex with ease. Nylon mesh lining wicks away moisture while 200 gram Thinsulate keeps you warm. EVA sock liner removes for convenience.
