This is a tough one. I’d love to get more feedback from other hikers on this. I’m a normal sized 5’4″ lady with size 8.5 feet and no real foot problems. I have been told I don’t need arch support. I do, though need better insoles!
I used green superfeet in my Merrill Moab mid boots, and they were okay but a bit too thick maybe and the arch felt like it wasn’t in quite the right place. I suffered no ill effects, and I’m sure they’re way better than nothing. Hiking 16 mi per day for 3 weeks my dogs were barkin’ fearcely in a general throb. IMO the Moab shoe is inadequate for uber-rocky terrain and that was my problem, I needed a shoe with a stiffer sole.
The PCT isn’t so rocky, but I’m trying a new shoe, Patagonia Drifter A/C. It has a knobby vibram stiff sole, is very breathable, has tons of room to wiggle the toes. My heel is slipping a little, so I’m thinking the Superfeet green or berry might work good in this shoe. I want to try them out for myself first.

Or there’s other moldable types… sheesh these are pricey- but why?
Powerstep moldable orthodics have good ratings but seem geriatric
Then there’s Dr. Scholl’s machine that tells you what your feet need- but nobody seems like what it tells them!
