Full-Grain Leather Upper

To ensure its quality, we put our leather through six different tests before making our selection. Our full-grain leathers are the strongest and most durable form of leather.

Waterproof Danner® Dry

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

Electrical Hazard (EH) Rated

Built with non-conductive soles to help protect against electrical shock in dry conditions, meeting ASTM F2413 safety standards for electrical hazard (EH) resistance.

Aluminum Toe

Our aluminum safety toe provides a lighter alternative to steel and meets ASTM F2413 standards for impact and compression resistance.

Dual Layer Comfort Footbed

The Danner Dual Layer Comfort footbed is constructed from plush memory foam and polyurethane to provide instant and long-lasting comfort.

PU Midsole

With integrated polypropylene board to provide support underneath the entire length of the foot.

BOA® Fit System

Designed for precision, durability and speed, the BOA® Fit System provides an exacting fit engineered and guaranteed to perform. Tested in extreme conditions, including knee-high snow and muddy trails, the impact-resistant lacing system replaces conventional laces and delivers the perfect fit and effortless adjustability on the go.

Danner® Caliper Outsole

The oil-and-slip-resistant rubber Caliper Outsole offers versatile indoor and outdoor traction with a low-profile 90° heel.
