When assembling these Comfort Core Logger work boots, Georgia Boot utilized Goodyear welt construction to strengthen the entire structure of these men?s boots. They combined full-grain leather and Armortex fabric (made with Kevlar) to give the upper incredible strength and the ability to resist abrasions. They made the hardware out of solid brass and outfitted the work footwear with Georgia Boot laces that are guaranteed for life. To add stability, they incorporated a counter lock rubber heel on the back of this Logger. The brush guard kiltie (removable) serves as a barricade, so external items will stay where they belong and you don?t have to worry about removing your boots to get rid of an annoying pebble.
