Redback Boots USA introduces the UBBK 6" classic slip-on boot, with a new and improved insole. The black, ergonomically designed insole provides technicians enhanced support when they are on their feet all day. The new anti-bacterial, anti-fungal lining, which is woven into the sole helps control odor while killing off harmful strains of bacteria that are often the source of foot infections. TPU soles provide sure footing and PU shock absorbing midsoles take the beating so a technician's body doesn’t have to. ASTM F2410-05 certified steel toe or soft toe options.
