How to Protect Your Feet During a Long Mountain Trek
Buy hiking boots half a size larger to accommodate swelling and protect toes downhill.
Choose merino wool socks and avoid cotton, which holds moisture against the skin.
Use heel-lock lacing to reduce heel movement and friction inside the boot.
Apply medical tape to blister-prone areas before walking and treat hot spots immediately.
Air, elevate, and gently massage your feet at camp to support recovery.
