We take pride on producing America's most comfortable work boots. The Carbo-Tec LT is a Goodyear welt constructed steel toe waterproof work boot; designed for a lightweight feel with heavy duty performance. The upper is made from our premium barnyard proof SPR leather. It has leather pull straps and a back zipper for easy pull on. The Counter Lock System locks your heel in place to prevent slippage when you walk and acts as a protectant when kicking off your boot. The Ergo-Fit steel toe cap is designed to match the shape of your foot. It gives your toes more range of motion while still maintaining ASTM F2413 I/C 75 impact and compression standards for safety toe footwear. The inside is lined with soft mesh material and equipped with the Georgia Waterproof System. The removable Quick Response insole is made from a polyurethane foam. It compresses as you step and quickly bounces back to its original form. The foundation of this boot is built for ultimate durability. A fiberglass shank adds stability and arch support while the thick EVA midsole acts as a shock absorber and cushions with each step. The Carbo-Tec Rubber outsole is made of our special blend of rubber that makes it heat, chemical, abrasion, oil and slip resisting. It meets electrical hazard standards for protective toe footwear as outline by ASTM F2413.
