Made from a soft black leather upper, and herringbone patterned elastic, the #600 is a classic boot built for comfort. With leather lining to make it easier to slide on and off, and hidden stitching in the heel for added durability, the #600 will work as hard as you do. Featuring XRD Technology for supreme impact absorption and a PU midsole for improved comfort and cushioning, the #600 has been designed to provide ultimate protection and support, reducing fatigue and orthopaedic problems in the lower back, legs and feet. The TPU outsole is oil, acid and organic fat resistant, and provides durability and grip on uneven surfaces.
