5.11 Tactical A.T.A.C.® 2.0 6" No-Zip Boot Black 12401

Overview of the 5.11 Tactical A.T.A.C.® 2.0 6" No-Zip Boot | 12401

The 5.11 Tactical A.T.A.C. 2.0 6" No-Zip Boot is the lace-up duty boot relied on by law enforcement officers, military personnel, and public safety professionals who spend long hours on their feet every day. This is the boot worn by leading public safety agencies worldwide, now updated with more comfort features without sacrificing durability.

Style 12401 combines a polishable full-grain leather toe and a 840D nylon upper with comfort-forward technologies that make an all-day patrol feel manageable:

• Dual durometer Ortholite® footbed for full-length cushioning and arch support
• Achilles heel flex zone for a natural stride that reduces fatigue
• Air flow breathable tongue to keep heat and moisture in check

The 5.11 Shock Mitigation System® absorbs hard surface impact mile after mile, and the oil- and slip-resistant outsole keeps your footing sure on wet pavement, slick floors, and uneven terrain. At 6 inches of height, this boot gives you solid ankle support without restricting agility.

Key Features

• Upper Construction: Full-grain leather toe cap (polishable for inspections) paired with a lightweight 840D nylon shaft for durability and breathability
• Footbed: Full-length dual durometer Ortholite® footbed provides responsive cushioning across the heel, arch, and forefoot for extended comfort on hard surfaces
• Achilles Heel Flex Zone: Engineered flex point at the rear of the boot allows natural ankle movement and reduces lower-leg fatigue during prolonged activity
• Air Flow Tongue: Breathable tongue construction channels air through the upper to manage heat and moisture buildup during long shifts
• Ortholite® Achilles Cuff: Padded collar with Ortholite® foam at the ankle for comfortable contact and reduced heel slip
• Shock Mitigation System®: 5.11's proprietary midsole technology absorbs and disperses impact energy from concrete, asphalt, and hard station floors
• Strobel Construction: Lightweight stitched-in footbed platform supports a slimmer, more athletic silhouette without adding bulk
• Outsole: Oil-resistant and slip-resistant rubber lug outsole with deep channeled tread pattern for traction on slick and uneven surfaces
• Closure: Traditional lace-up with metal eyelets and a pull loop at the collar; no side zipper
• Shineable Toe: Full-grain leather toe cap accepts standard boot polish for a professional appearance at formal inspections
• Boot Height: 6 inches for ankle coverage and support with freedom of movement
• Color: Black
• Width Options: Regular and Wide
• Country of Origin: Bangladesh

Compatibility

The 5.11 A.T.A.C. 2.0 6" No-Zip Boot (Style 12401-019) is designed for men's sizing and fits a wide range of foot types. Regular width is available from size 4 through 15. Wide width is available from size 7 through 13, making this boot accessible to wearers who typically struggle to find a comfortable duty boot without needing special orders.

This is the lace-up No-Zip version. It does not have a side zipper. If you prefer a quick-release zipper entry, the A.T.A.C. 2.0 Side Zip (a separate model) is the correct choice. The lace-up configuration gives a more traditional fit that many patrol officers prefer for its secure, customizable hold throughout a long shift.

This boot is not waterproof and not insulated. It performs well in dry to moderate conditions and is designed for breathability and all-day comfort rather than wet-weather protection. If your assignment involves consistent wet environments, consider the A.T.A.C. 2.0 Shield with its waterproof membrane.

The Ortholite® footbed is compatible with most standard aftermarket orthotics if a prescribed insole is required. The lug outsole and toe cap styling meet the black boot dress requirements of most law enforcement and public safety agencies, and the polishable leather toe satisfies formal inspection standards.

Intended Users

The 5.11 A.T.A.C. 2.0 6" No-Zip Boot is built for professionals who are on their feet for entire shifts and cannot tolerate footwear that sacrifices comfort for appearance or vice versa.

Law enforcement officers on patrol, in corrections, or in investigations rely on this boot for all-day wear that still meets department appearance standards. The polishable leather toe checks the box for inspections, while the Ortholite® footbed and Shock Mitigation System® handle the physical demand of foot patrol on concrete and asphalt.

Military personnel and tactical operators choose the A.T.A.C. 2.0 for training environments, base duty, and field operations where a lightweight and responsive boot with proven construction is needed.

Security officers and private protective services professionals appreciate the professional black colorway, the slip-resistant outsole for lobby and retail environments, and the wide size range that accommodates officers across a broad spectrum of foot types.

Emergency responders and public works personnel who spend significant time on their feet in demanding conditions find the breathability, cushioning, and traction combination well-suited to their work environments.

Outdoor enthusiasts, preppers, and serious hikers who want a field-proven duty boot for extended trail use or emergency preparedness also benefit from the A.T.A.C. 2.0's rugged construction and wide size availability.
