The Muck Boot Muckmaster is the ultimate outdoor boot and is ideal for sport anglers. The boot features a reinforced toe cap and Achilles tendon protection. The boot also has a soft nubuck finish on the neoprene, and it is easy to put on and take off. The boot has a removable insole for extra insulation and comfort. This helps the foot maintain a comfortable temperature and wicks away moisture. The 4-sided stretch nylon in the shaft creates no wrinkles. The outside is made of 100% waterproof and insulating neoprene and finished with an anti-stick sole with coarse tread. The neoprene insulates against cold and heat. Warm in the winter and cool in the summer!
