Staying in the fight requires staying on your feet. Our A/T™ 8 HD boot brings all the features you demand in tactical footwear and adds touches rarely seen in a professional boot. The A/T 8 HD is ISO 20347:2012 OB FO HRO SRA certified. The perforated tongue adds breathability and air flow, critical to keeping you cool during a tough mission. A heat-reflective strobel sock reflects heat from pavement and concrete away while a new, infrared refracting leather drops surface temperature. Combined with our A.T.L.A.S. All Terrain Load System, A.T.L.A.S. plate, and high-traction outsole with an Ortholite footbed and pulling those long shifts has never been easier on your feet. Imported. Explore the 5.11 A/T Series.
