Over four years in development and tested over 4,000 miles, the LaCrosse Aerohead Hunting Boot is truly revolutionary. This waterproof, scent-free boot features LaCrosse's patent-pending AeroForm technology, a groundbreaking new construction offering an extremely comfortable fit. The shell around the 3.5mm neoprene core is molded with liquid polyurethane, which is more durable, flexible, insulating, abrasion-resistant, and more lightweight than rubber. An Armor Weld liquid rubber protective coating on the seams ensures long-wearing durability. The jersey-knit liner dries quickly and wicks away moisture to keep feet ultra-comfortable. The injected PU midsole offers added cushioning with an integrated shank to cover the arch of the foot, providing support and stability when climbing on ladder rungs. The Ankle-Fit design locks the heel in place to prevent excess rubbing and chafing. The lightweight, non-loading Aero rubber compound outsole provides superior durability and traction on muddy terrain. The back gusset and strap adjust easily to fit a variety of leg sizes. Rated for temperatures as low as -30°F. 18" shaft height. Weight: 4 lbs. Medium width. Imported.
