Not only was this boot built to satisfy your needs for safety but with the addition of Georgia?s unique patented Comfort Core Insole? technology your feet will feel pampered all work day long. The Comfort Core? features specially-designed energy-return cushioned insoles that actually store energy when the weight of your foot compresses them, then releases that energy as you walk. An air flow system has been incorporated to add dozens of tiny air holes that force air through the insole as you walk so that your feet stay drier and cooler longer. Other features: Oil, heat and slip-resistant rubber mini-lug outsole and heel Unlined shaft Taped and stitched side seams Steel shank Safety toe class 175/C75 Imported
