Reengineering their proven work boot comfort system, LaCrosse has taken Quad Core technology and redesigned it specifically for hunting boots. For the first time ever, the Quad Core 4-layer comfort platform system has been integrated into the LaCrosse 4xBurly Hunting Boot for uncompromising scent-free, waterproof protection as well as underfoot comfort and support. All-natural handcrafted rubber is bolstered with 800 grams of Thinsulate Ultra insulation for premium warmth in cold-weather conditions. Added rubber in the toe, heel, and shin provides exceptional abrasion resistance for long-lasting wear. The triple-layer sponge rubber midsole offers just the right amount of cushioning, while the contoured Ankle-Fit design prevents heel slippage for extra stability. The dual-density molded PU and sponge rubber footbed provides added support where you need it most, and the 4xBurly outsole yields superior traction in snow, mud, and loose terrain. The back gusset and strap adjust easily to fit a variety of leg sizes. Rated for temperatures as low as -50°F. 18" shaft height. Weight: 6.2 lbs. Medium width. Imported.
