Military personnel around the world rely on their Belleville’s. Belleville relies on Vibram Chevron. With one look at the heel and forepart you see the time-tested and proven Chevron design, recognized for its traction while still being FOD (Foreign Object Displacement) friendly. The Chevron’s self-cleaning channels off the perimeter keep the sole free of debris. The wide, flat outer surface and shank bars come together to give a confident footing on level ground and ladder rungs.
