Last Friday we finished a 12 mile ruck and the soles of my feet were sore, which is a pretty new development for me. Typically it's my shoulders or quads. I was wondering if anyone else has had a similar issue and whether they tried fixing it by changing their gait or simply buying new insoles for their boots. I'll say that the boots I wore for this 12 miler weren't any different than the ones I've worn in the past, so I'm a little perplexed as to why my feet felt so bruised, but I've felt it a couple times after week long field problems too. I've looked through a bunch of rucking threads but haven't seen anything about sore soles specifically so any advice or experience would be much appreciated.
