We built this taller 12" version of our popular all-season 6" Alpha Deck Boot to give you even more waterproof protection. Whether you&';re on deck or land, the slip-resistant outsole keeps you surefooted. A double-reinforced toe box and heel cup resist cracking better than the competition, while our signature Air-Circ liner system regulates airflow for all-day comfort in any weather. Plus, half-sizes and width options ensure a dialed-in fit you won&&';;t find in most rubber boots. Alpha Construction Built with hand-laid premium, natural rubber over insulating neoprene for durability, flexibility and complete waterproof protection. Air-Circ Liner Quick-drying mesh that circulates air inside the boot when you walk, keeping your feet cooler, drier and infinitely more comfortable. Alpha Fit Alpha Fit provides half sizes and multiple widths for a comfortable, precise fit. Kick-Off Heel Plate For easy hands-free removal. Foredeck Outsole This slip-resistant outsole is versatile and designed to provide traction in the wettest environments. Designed for Extreme Use This style was designed for extreme use and is made with PFAS Chemicals.
