The Mongrel 561020 High Zip Safety Boot in Black is designed to meet every need on the worksite, and deliver superior, all day long comfort. The high leg lace-up boot gives ankle support where it is needed, and side zip gives easy-on easy-off convenience when the day is done.   The OrthoTec PU Air innersole is a long wearing and comfortable footbed that incorporates the patented AirZone system. This circulates air around the foot, assisting moisture control while giving the wearer all day comfort. The boot is lined with Dri-Freeze® lining that dissipates heat, ensuring the wearer experiences cooler, drier feet.   The 200j steel toe has been tested to Australian safety standards, for peace of mind on the worksite. The steel toe lies beneath a moulded PU scuff cap for longevity of the boot. Other features include an oil & acid resistant Vibram outsole with SRC slip resistance, that is heat tested to 300 degrees.     200J steel toe cap Heat, oil & acid resistant Vibram XS Work outsole Moulded PU scuff cap for longevity YKK zipper w/ full length ZipGuard SRC slip resistance Silicone AbrasionGuard AirZone Comfort System® OrthoTec PU footbed w/ anotomical arch support Dri-Freeze® lining that dissipates heat Coats NylBond stitching Padded tongue and collar Certified to AS 2210.3:2019 Australian Made Mongrel 561020 High Zip Safety Boot Rubber Black
