The LaCrosse ZXT Guardsman Rubber Boot is built to perform under the harshest conditions, with a fit designed to keep you secure and comfortable while doing so. The natural, hand-laid ZXT rubber upper remains durable and waterproof year after year, and is specially formulated to be ozone- and tear-resistant for even greater protection. LaCrosse’s revolutionary Ankle Fit design ensures a secure and comfortable fit around the ankles, while gripping the top of the foot and locking the heel in place. The adjustable top strap further customizes the fit around the calf. The removable EVA footbed provides optimum cushioning underfoot, and the steel shank adds extra stability where you need it most. The fully vulcanized Guardsman rubber outsole delivers slip-resistant traction over muddy, snowy terrain. 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. 6.4 oz. Medium width. Imported.
