Belleville | 340 DES ST Hot Weather Steel Toe Flight Boot


The Belleville 340 DES ST is the first U.S. Army approved hot weather flight and combat vehicle boot. It features a boot upper made of fire-resistant NOMEX fabric that is designed to perform in extremely hot temperatures, providing maximum protection when you're in the fight. The anti-microbial lining is resistant to mold, odor, and bacterial growth. A lightweight steel toe provides protection from falling hazards. The unlined upper provides the best cooling needed when operating in hot temperatures. The 340 ST also features a VIBRAM Sierra out sole with large lugs for excellent grip on both loose or smooth terrain. This boot is approved for wear with the Army Combat Uniform, approved for U.S. Army Flight and Combat Vehicles, and is Berry Compliant.
