Classic on the outside. Exceptionally capable on the inside.

The Avenger walking boots combine the timeless appearance of a traditional leather walking boot with premium performance technology hidden beneath the surface.

At its heart is a Sympatex® membrane—waterproof, windproof and highly breathable—to help keep your feet dry and comfortable in demanding conditions. Unlike many conventional membranes, Sympatex® is exceptionally flexible, allowing it to move naturally with the boot without compromising protection.

The clean, minimal-seam construction gives the Avenger its smart, understated appearance while also reducing potential points of water entry. Premium waxed leather adds durability and character, developing an even richer appearance with wear.

Underfoot, a rugged Vibram® sole provides dependable traction, while the cushioned midsole and R-System arch support deliver comfort and stability across uneven terrain.

Traditional styling, premium materials and serious all-weather performance—the Avenger is a classic walking boot built for modern adventures.
