I had not one blister on my AT thru hike. I put it down to a little luck and this:-
- Good fitting boots
- Sock liners and top quality hike socks
- Clean socks every day. Its a great feeling to start the day with clean socks. I used to wash my socks and underwear daily in a zip lock bag.
- For about 6 weeks prior to my hike I used to walk the last 2km of my daily walk bare foot. It was very hard at first but boy did my feet toughen up.
