The LaCrosse ZXT Knee Boot delivers extreme mud and waterproof protection for active endeavors in even the worst conditions. Lightweight and always long-wearing, the natural, hand-laid ZXT rubber upper won’t crack in the cold, won’t get soft in the heat, and won’t ever let you down when you need it most. Plus, it’s specially formulated to be ozone- and tear-resistant for even greater durability. The removable EVA footbed provides optimum cushioning underfoot, and the fiberglass shank adds extra stability where you need it most. An extra layer of rubber is added underfoot and around the instep for added protection during shovel impact. A second layer of rubber is added to the toe for stronger abrasion resistance in this high-wear area. The extra-durable Trac-Lite outsole is fully vulcanized, ensuring that it won’t ever separate from the upper. Its 90° heel and versatile, gripping lug pattern yield slip-resistant traction on mud, snow, and wherever else you tread. The plain toe is designed to meet or exceed ASTM F2892-11 EH safety standards. Uninsulated. Comfort range: -20° to 70° F (-29° to 21° C). 16” shaft height. Weight: 4 lbs. Medium width. Imported.
