Don’t push yourself too hard. It’s important to let your feet (and the rest of your body) rest at regular intervals.
If your feet are feeling sore, wet, or just a bit cramped, then stop. Sit down, get your feet out in the air, and change your socks over. It will help reduce the likelihood of friction and pressure points building up which lead to blisters.
Jeremy says "If you feel a hot spot developing, early treatment is the key. Don’t ignore it – it will only get worse. Applying a specialised blister plaster (Compeed) over the hot spot can be effective before it turns into a blister.
You might want to swap into dry socks, if you have them. And when you re-lace, make sure you have the most secure fit possible to minimise movement and friction."
Dehydration can affect your skin's elasticity and general foot health, making skin prone to blisters (especially over greater distances).
Stay hydrated with a water reservoir pack, which gives you the ability to carry more water using your body weight for support.
Also, remember to pack nutrition bars and easy-to-carry snacks to keep your energy up along the way.
