The Apex Collection, all new from The Original Muck Boot Co. The Apex is a high-performance hunting boot built on an innovative platform for high endurance outdoor pursuits requiring a more athletic and agile boot. 100% waterproof and coupled with breathable mesh linings to provide elite protection and moisture management. The upper features a lock-down zipper closure system, a natural scree collar and surprisingly light-weight performance for great comfort and fit. Equally at home on loose rocky terrain, cold/wet ground and of course, the MUCK.
