I wish! No, I'm a pretty small dude, 5'7, size 10 1/2 shoe and have weighed about 170-180lbs most of my adult life. I got into lifting weights very late in life (29 years old...I'm 37 now), but have always been physically active my whole life with sports.
I do loaded carries mainly for the purpose of grip training and I don't have the real Farmers Walk Handles, I use 2 loading pins and attach either D-handles, Towels, Rolling Thunders or Elitefts Grenades to walk with. I also have those "Swing Set Straps" Spud Inc sells, but don't do that as often and I have never gone beyond double my body weight.
Now weigh 190-195lbs range and the pain in both feet I believe started when I reached that bodyweight. It hurts the most after loaded carries and I think my feet might be slowly changing (losing arches, bone above the pinky toes never had that feeling before, I believe they call it a "bunionette"?). I was just curious if others have had this kind of problem and know ways of fixing it or if I'm a uncommon case.
