Overview of the 5.11 Tactical A.T.A.C. 2.0 8" Side-Zip Duty Boots | 12391

The 5.11 Tactical A.T.A.C. 2.0 8" Boots duty boots | 12391 are built for the demands of public safety work, with a lighter feel and improved comfort while keeping the toughness the A.T.A.C. line is known for. The brand positions this as the boot worn by leading public safety personnel, and it is designed to help you stay comfortable through long shifts, repeated movement, and changing conditions.

Cooler, Drier Comfort for Long Shifts

When you spend hours on your feet, heat and moisture add up fast. The airflow tongue helps move air, while the full-length dual durometer Ortholite® footbed supports comfort all day. From the images, you'll see a padded collar and structured build that helps the boot feel stable without looking bulky.

Mobility, Protection, and Fast On and Off

A key upgrade is the Achilles heel flex zone, which helps increase range of motion without giving up support. The full-grain leather toe and 840D nylon upper add rugged protection, and the boot also uses a shock-mitigation system to help reduce harsh impact. A YKK® side zipper speeds up entry and exit. A built-in knife pocket keeps a small tool close when you need it.
