The 65 series outsole is heat-resistant to temperatures up to 300° C and highly resistant to mineral oils, acids, alkalies, animal fats and oils. This style features the XRD® Metatarsal Guard; Extreme Impact Protection. XRD® technology is not only comfortable, flexible and lightweight but frees you of rigid, bulky and constricting stiffeners and weight of external metatarsal guards.
