This #6 Black Work and Safety Boot is designed to wear in homes as well as in outdoors. The heel strike zone of the midsole is made from XRD technology that absorbs heavy impacts thus minimizing pressure on the feet. Breathable footbed is made from PU material with anti-microbial properties. TPU outer sole endures up to 140 degree C and provides great resistance to slips, acids, oil, cuts and abrasion. Lace-up design on the front side gives good ankle protection.
