The boots' inner liner provides waterproofing via which material?

• A. Gore-Tex liner
• B. Leather lining
• C. Foam padding
• D. Cotton socks

Answer: (A)

Waterproofing in boots comes from a waterproof-breathable lining. Gore-Tex is a thin membrane used inside many firefighter boots that blocks liquid water from entering while still allowing moisture from sweating feet to escape. This keeps feet dry in wet or steam-filled environments and helps prevent heat buildup. Leather lining isn’t a reliable waterproof barrier by itself, even if treated. Foam padding is for comfort and insulation, not water protection. Cotton socks can actually soak up water and become cold, so they don’t provide waterproofing. So, the inner Gore-Tex liner is the best choice for true waterproofing.
