Everything you need and nothing you don’t – that’s what the LaCrosse 4xAlpha Insulated Boot is all about. Built with premium, hand-laid, natural rubber over 7mm of insulating neoprene, the 4xAlpha is more durable, more flexible, and more comfortable than its full-rubber counterparts. Multiple layers of rubber are used in the construction of this boot to keep your feet safe and sound. First, there are two layers in the toe guard and instep for extra durability in these high flex, high-stress areas. Next, three layers in the heel help withstand wear and tear when it’s time to kick off the boots. And to ensure that you always tread confidently through the brush, the 4xAlpha features a full shin guard for even greater protection. Quad Core technology boasts four layers of cushioning for optimum comfort and reduced foot fatigue. The removable polyurethane footbed provides additional cushioning underfoot, while the nylon shank offers extra support and stability where you need it most. The contoured Ankle-Fit design helps prevent heel slippage for even greater comfort. The fully vulcanized 4xBurly outsole is not only built to tread the most challenging terrain, but it also features high-grade premium rubber that won’t get soft in the heat, won’t crack in the cold, and won’t ever let you down when you need it most. Angled lugs keep you light on your feet by shedding the mud and muck, while a 90° heel and integrated shank make climbing a cinch. A durable, full-rubber gusset on the back accommodates different calf sizes and makes it easy to slide the boot on and off. The boot is designed to meet or exceed ASTM F2892-11 EH safety standards. Comfort range: -40° to 30° F. 16” shaft height. Weight: 5 lbs. 1.6 oz. Medium width. Imported.
