Danner Men's 8 in. Tanicus Side-Zip Boot

The Air Force-compliant Tanicus boot has a side zip for easy on and off. Aircraft mechanics working in freezing cold conditions will appreciate the 400g of Thinsulate Ultra Insulation. A non-metallic safety toe provides comparable protection to steel toes but doesn't get cold or set off metal detectors.

Rough Out Leather & 1000 Denier Nylon Upper

Danner's rough-out, full-grain leather upper is legendary for its durability. Danner pairs it with 1000 Denier nylon for superior protection.

Waterproof Danner Dry

100% waterproof barrier allows moisture to escape without letting water in, keeping your feet dry and comfortable all day long.

USAF Optional Wear

Meets US Air Force AFI 36-2903 requirement for optional wear.

Lace Garage

Prevents loose laces from snagging or dragging. At the top of the boot's tongue is a stretch fabric pocket designed to tuck your lace ends into.

400G Thinsulate Ultra Insulation

High-performance insulation that keeps you warm in the snow and rain without weighing you down.

Composite Toe (NMT)

Made from non-metallic materials, our composite safety toe does not conduct heat or cold and will not trigger metal detectors. As expected, it meets ASTM F2413 safety standards for impact and compression resistance.

Danner Tanicus Outsole

Pentagonal lugs give maximum surface contact for grip in a variety of terrain.

Extended Sizes

To accommodate more people, Danner has made this boot in extended sizes. Danner recommends women select 1.5 to 2 full sizes down for correct fit.

How It Fits

The 851 last is an update to Danner's popular 850 last. This last fits true to size with an athletic and supportive fit while providing ample room in the toe. Offering a specific heel shape that locks the heel in place for better fit and comfort on the back end of the boot, this supportive fit is ideal for those needing high mileage performance from their gear.
