Close on the heels of the original JOHNNY COMBAT(TM) Boot, comes the WP waterproof version. It is built on the same chassis as the original, but with the inclusion of a full waterproof/breathable lining. The bottom unit is our vetted STRIFE(TM) outsole for excellent outdoor traction & durability. NOTE: Our Waterproof Johnny Combat fits slightly smaller than the original Johnny Combat boot. We recommend ordering 1/2 size larger in this boot.
