Rancher tested; Rancher approved. The Carbo-Tec LTR steel toe waterproof pull on boot combines the durability and performance of our Carbo-Tec LT and Muddog collections for the ultimate farm and ranch boot. The upper is constructed from full-grain pasture proof SPR leather and a molded waterproof TPU shell. Contoured grip panels allow for an easy pull on of the boot. The Counter Lock System on the rear of the boot stabilizes the heel to prevent slippage. The interior of this wellington work boot features the Georgia Waterproof System and is lined in a high-performance mesh material. A 3-D molded counter pocket locks your heel into place and provides added support. The removable Quick Response polyurethane insole compresses as you walk and quickly bounces back to its original form to provide all day cushioning. The foundation of the boot is comprised of a fiberglass shank for added stability and a dual density EVA and Carbo-Tec Rubber outsole. It also features a protective steel toe that meets ASTM F2413 electrical hazard standards and protective toe classifications.
