These 8" Logger boots by Georgia are made with a waterproof construction that combines a waterproof inner layer with the upper providing a barrier that helps keep water out and feet dry. The contoured removable polyurethane cushion insole provides direct underfoot cushioning for maximum comfort. This polyurethane material that is used is known for its cushioning while not bottoming out. These boots meet the highest ASTM F2413-05 Impact & Compression standards and they comply with Electrical Hazards 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.
