If you cross paths with a snake while hunting doves or fixing fences, it helps to be prepared. The Sharptail guards against rattlers, copperheads and other venomous snakes with flexible 360° protection. The full-grain leather and durable textile upper stands up to thick brush and sloppy trails. Feet stay dry on marshy ground thanks to a breathable Gore-Tex liner. A side-zip gets you in and out quickly, which comes in handy when your boots are muddy or covered in poison oak. The 851 last is an update to our popular 850 last. This last fits true to size with an athletic and supportive fit while providing ample room in the toe. Offering a specific heel shape that locks the heel in place for better fit and comfort on the back end of the boot, this supportive fit is ideal for those needing high mileage performance from their gear. We use a flexible snake protection fabric in between the liner and exterior of the boot to give you complete snake protection from the bottom of your foot to the top of the boot.
