Made with a 5mm CR Flex-Foam neoprene upper, the Muck Fieldblazer Classic Boots offer plenty of flexibility to reduce discomfort and potential blisters, while the bioDEWIX antimicrobial footbed inserts help offer odor control and moisture management. Additional features include a fleece lining for warmth, a pull tab for easy on, and a wide-tracking rubber waffle outsole for traction on a range of different surfaces.
