Is there a foot guide for foot issues? Like what styles to look for, or what after-market tailoring can do (ie, foot petals, insoles, etc.)

I have low volume feet and narrow ankles and am always getting blisters when I wear sandals because they never fit as snuggly as they should. I have a pair of Clarks that I like, but the back is velcro and I can't make it any tighter. Result: blisters and I am currently soaking my feet in the tub.

Anyway, it seems boots are the best, as they don't fall off. But I'll have to wait a few more months for those.
