Also- be sure to take your measurements and compare them to the boot measurements! I know it sounds obvious but you wouldn't believe how many people don't lol
I'd look at boots that come in Short/Wide for height and calf size. Then from there, narrow it down to ones that carry your foot size. If you can't go into a store and try them on, order them from a website that offers free return shipping (like Smartpak)
Parlanti, you can customize the size at a pretty wide range without having to order custom made boots!
Ariat boots are really great, of course I advise you to try them to make sure it fits!
