comfy shoes

I have very BAD feet that blister easily. so I need comfy shoes. i found the perfect shoe that will prevent blisters cause all the straps are made of silk, but they are flats. i am only 5'3' so flats are not the best. especially cause my fh is tall.

does anyone know where i can find shoes, or where i can go to get some height added to the great shoe i found?

TIA
