Focus on the Mission, Your Feet Are Covered
With the same rough-out leather and rugged nylon expected from Danner, the Tanicus is built to be Danner's lightest military boot that's still theater ready. An added layer of cushioning in the midsole and a dampening heel cup, paired with a polyurethane footbed, keep comfort from breaking down over time.

-
Lace Garage: A stretch-fabric pocket at the top of the tongue keeps loose lace ends tucked away, preventing snagging or dragging.

Danner® Tanicus Outsole: Pentagonal lugs give maximum surface contact for grip across varied terrain.
-
851 Last: An update to Danner's popular 850 last, fitting true to size with an athletic, supportive fit, ample toe room, and a specific heel shape that locks the heel in place for high-mileage performance.
Built for Cold-Weather Flight Line Duty
Aircraft mechanics and anyone working in freezing conditions get 400G Thinsulate™ Ultra insulation and full waterproofing on top of the composite toe and side zip — a genuine cold-weather counterpart to the hot-climate 55322.
