Preventing Blisters on the Long Walk
Your boots are your vehicle. If they fail, your Everest trekking adventure fails. Fitting them correctly is an art. Here is how to ensure comfort on the trail.
Your feet will swell at altitude. Buy boots a half or full size larger than your street shoes. Your toes should not touch the front when walking downhill. This saves your toenails on the return from Everest Base Camp.
Wear a thin liner sock under a thick wool sock. This reduces friction on the skin, preventing blisters. Test this combo before your Mount Everest expedition.
Walk at least 50km in your boots before flying to Nepal. They need to mold to your feet. Never bring fresh boots to the Himalayas.
Learn to use the locking hooks. Tighten the ankle for downhills to prevent toe jam.
