The Georgia Logger insulated Gore-Tex steel toe work boot is made with a Gore-Tex waterproof construction. This fabric is a micro porous membrane structure, which means no external moisture (rain, snow, sleet, or puddles) can penetrate the fabric, but internal moisture from perspiration can easily evaporate. This work boot also contains 400 grams of Thinsulate Ultra insulation to help keep feet warm. An additional comfort feature of this boot is its contoured removable polyurethane cushion insole that provides direct underfoot cushioning. The polyurethane material used in its insole is known for its cushioning while not bottoming out features. Its Vibram rubber outsole is made with a high quality rugged compound and has a well defined heel to aid in logger applications as well as various rung climbing related uses. In addition to meeting the highest AS F2413-05 Impact & Compression standards, it also complies with its Electrical Hazard standards. This type of work boot is made with insulating bottoms providing secondary electrical hazard protection to those areas dealing with open circuits under dry conditions, but can also be worn in work areas requiring only basic protective toe work boots.
