>>161381As soon as I stopped wearing cotton socks, the blisters stopped happening. I threw away every pair years ago and never looked back. I use wool and/or synthetic socks, usually labeled "hiking socks" at your local /out/doors type store that sells footwear.
Pic related, Keen hiking shoes. I like this brand, broader toe box, fit like bedroom slippers. I can walk forever in these and my feet never hurt, which used to be a problem. I use these backpacking, hiking, whatever.
