From my experience in the Army when climbing mountains overseas moleskin worked really well for me. A propperly fitted shoe is also important, too big or small will leave you limping home.
>>562267>>562279Moleskin worked for me. When we did our first ruck I realized my boots were too small and ended up with blisters. After healing up from that and getting the right fit boot I put moleskin on the problem areas of my foot. ie: the heel, under the big toe. The one on the bottom of my foot always fell off after a few miles and the one on the heel was always a hit or miss. But it provided comfort for however long it lasted.
>>562343>>562344I've heard a lot of people say to wear double socks and it did quite the opposite for me. The few times I did try it climbing up and down mountains all day the sock in between my foot and the outer sock would somehow get a wrinkle and after walking a few miles on the wrinkle a blister would develop. Maybe I had the wrong combination of socks but I know I'd rather just go with one sock on each foot than deal with that misery again.
>>562395Great info here.
I used the Dr. Scholls brand moleskin and it helped a bit but like anon said inevitably it would eventually fall off. I definitely agree with anons comment about foot powder it works but it gets absorbed pretty fast.
tldr: Use moleskin before you get blisters in known problem areas on your feet. Wear one sock on each foot. Every time you stop to rest, loosen up your boots allow your feet to breathe/dry and put on dry socks and continue your hike.
