The boots worn by the world's leading public safety personnel, the 5.11 Tactical ATAC 2.0 Side-Zip Duty Boots for Men just got promoted. These men's tactical boots now perform with a lighter and more comfortable build, yet maintains their reputation for toughness and durability. A new airflow tongue and full-length dual-durometer Ortholite footbed works to keep your feet cool, dry, and comfortable all day, every day. Another updated feature, the Achilles heel flex zone, gives a critical part of your foot more range of motion without compromising support. The full-grain leather toe, 840-denier nylon upper, and shock mitigation system provide the kind of rugged protection you need, while the knife pocket keeps an important ally within reach. The Agion odor-reducing treatment keeps these 5.11 boots fresher than ordinary men's duty boots. Imported.Manufacturer style #: 12391-019.
