Inspired by LaCrosse’s 1963 Burly boot, the Insulated Pac is a do-it-all rubber boot that you can always count on to get the job done. The natural, hand-laid ZXT rubber upper remains durable, waterproof, and scent-free year after year, and is specially formulated to be ozone- and tear-resistant for even greater protection. Insulating foam extends from the bottom of the foot to the ankle for ample warmth in cold-weather conditions. 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 removable EVA footbed provides optimum cushioning underfoot, and the fiberglass shank adds extra stability where you need it most. A second layer of rubber is added to the toe for stronger abrasion resistance in this high-wear area. The Chevron Cleated outsole is fully vulcanized, guaranteeing that it won’t ever separate from the upper. Its unique lug pattern sheds mud and muck for unparalleled traction even in the thickest of mud and the nastiest of terrain. Comfort range: -20° to 70° F (-29° to 21° C). 12” shaft height. Weight: 4 lbs. 14.4 oz. Medium width. Imported.
