Military aviators require boots that are specifically designed for the cockpit and flight-line environment. The Belleville 330 DES ST Tan Hot Weather Steel Toe Flight Boot was designed for U.S. Navy and U.S. Marine Corps Aviators looking for a top performing desert flight boot with steel toe protection. This boot features an upper made of Pure Tan Leather and flame-resistant WT-2 Flight Approved Fabric. It features the Vibram Chevron outsole which was designed specially for the flight line because its sole pattern resists attachment to foreign object debris (FOD). The Belleville 330 DES ST features the Vanguard running shoe design to give you an athletic fit and feel. This boot is Berry Compliant and made in the USA.
