This Georgia Muddog work boot has been made from a combination of tough yet soft brown leather and a . Tpu shell. The shell is phenomenal because it obstructs water from getting into these boots, allows you to slop across mud-covered terrain without having the leather covered from top-to-bottom in it, plus it provides great protection against abrasions. The lace-up design is another great addition to the upper of these waterproof boots it allows you to adjust the fit throughout the day and allows your feet to rest securely down inside of these boots. When you are wearing these work boots your feet will be shielded from falling objects and will be protected against electrical exposures. The footwear has been assembled in such a manner that allows it to meet the rigorous criteria set by the Astm F2413 I/75 C/75 Protective Toe Classification and the Astm F2413 Electrical Hazard Standard. The work boot's steel toe can withstand up to 75 lbs. of impact and compression.
