The secret to avoiding blisters on long trails isn't better boots, it's changing your socks every 2 hours
I hiked the John Muir Trail last summer and my feet were a disaster by day three. Blisters on both heels, tops of my toes, even between my arches. I tried expensive socks, different lacing patterns, and two kinds of tape. Nothing worked until a thru-hiker I met at Muir Trail Ranch told me to just stop and swap socks every 2 hours on the dot. I thought he was exaggerating but I gave it a shot. I carried six pairs of thin wool socks and rotated them out even if they didn't feel wet. By the end of the 210 miles I had zero new blisters. Has anyone else tried this or do you do something different for foot care?
