First, I am really, really sorry to hear about your foot issues. They are no fun.
I am also in the less than 2" heel club, with my preference between right around 1-1.5 inches. I can tell you it is trickier to find shoes, but not impossible.
Here are some brands I have found very comfy even if I didn;t buy them because of style. Note you really have to poke through the styles. Some are fab, some are granny. These are mostly practical shoes, so not as fashionable.
Trotters
Munro
Aetrex
Ara
Aravon
Beautifeel - I have not found any I liked and could afford yet, but they feel lovely on.
Clarks
Dansco
Earthies
Ecco
Josef Siebel
Mephisto (usually expensive and ugly, but wow do they feel good!)
Naot
Orthaheel
Pikolinos
Rieker
UGG
Walking Cradles
I am sure there are many, many more. I have some from Dolce Vita that are fashionable and comfortable, BUT I don't have the same restrictions you do. I just know if the heel is over 1.5" or so, my body will not be happy.
Would an orthodic insert open more doors?
