The Field Assault Boot is built to be as tough as you are: featuring a stitched-down Vibram outsole that delivers traction, stability, and flexibility, while protecting your feet from the elements. The 8-inch Cordura suede upper is made of lightweight and abrasion-resistant fabric that lets your foot breath. The EVA insole and polyurethane midsole provide comfort with a custom fit that provides stability and shock absorption. The Lace-Lock system features a quick-on-off system that incorporates braided, nylon laces that are durable and create a locked-in fit.
