Blisters form through friction, with the foot rubbing as you walk. They are worsened by hot, damp conditions.
Blisters can be surprisingly painful and can greatly impact your expedition if not taken seriously.
Ensure your boots fit properly; if buying a new pair take the time to make sure they are right for you feet
Ensure your boots are well worn in; new, stiff boots WILL cause blisters
Treat your boots with a waterproofing product like Nikwax
Invest in good quality walking socks - they really make a difference!
Trim & file your toenails; ensure there are no sharp bits
Pack some light trainers/sliders for evening on camp to let your feet rest
Ensure your boots are tied securely to reduce movement
Wear dry socks each day
Take your boots & socks off during longer breaks to "air" your feet
Take care of your feet! keep them clean & dry; its a good idea to bring some foot cream or powder to apply and give them a good rub each evening
Act immediately if you have a "hot spot" or think a blister is forming

If a blister does form -
Stop immediately and treat the blister straight away. A short break will reduce the likelihood of hours of pain later
Clean the area with a cleansing wipe from your First Aid kit and allow to fully dry
Apply a Blister Pad (such as “Compeed”) over the affected areas. These act as a “second skin” and allow the blister to heal, and the new skin to grow and harden.
Avoid popping blisters. There will be new skin underneath that is raw until it heals. Popping the blister exposes this to further rubbing and possible infection, so will be just as painful.
