The boots should be constructed from flame-retardant, waterproof leather or high-grade heat-resistant rubber. Key technical features must include a steel or composite toe cap (impact resistance >200J), a puncture-proof midsole (penetration resistance >1100N), and an anti-static, slip-resistant outsole capable of withstanding temperatures up to 250°C-300°C. For comfort and hygiene, a breathable, waterproof membrane (like GORE-TEX or equivalent) and a moisture-wicking lining are essential for long-duration missions.
