For a comfortable, reliable and ultra-protective postal boot, Rocky presents the TMC Postal Duty. This boot is designed for people on their feet all day, who require critical cushioning and long-lasting comfort. Built with an Air-Port cushioned footbed, the insole promotes superior breathability and ventilation through the boot, to prevent overheating and sweat build-up. The full-grain leather upper looks professional, features a polishable toe and is water-resistant, so rain and snow are never an issue. There is an Aegis antimicrobial treatment on the footbed that reduces odor-causing bacterial growth and maintains a healthy, clean interior. The non-metallic stabilizer provides torsional rigidity and arch support, and the direct-attach outsole is slip and oil resistant for maximum grip on any surface.
