After years of studying how their boots are worn, Muck Boots have designed a new upper on their traditional Woody Sport outsole. This new ankle height boot features a 100% waterproof insulated upper. It is built to keep you dry and comfortable all day long thanks to the cool weather lining. It features abioDEWIX dry footbed topcover with NZYM for odor control and moisture management, along with a rugged rubber outsole for enhanced traction underfoot.
