Classy flat shoes to wear with 'classy' clothes? Do they exist?

[BelladiNotte]

Help, please!
I've developed a neurological condition, can't walk well, v. Poor sense of balance, think it's permanent, so all my gorgeous heels have to go. Gutted! I SO love my shoes.
So I'm looking for lovely flat shoes with a bit of pizzazz about them. Think I could manage a small wedge for a bit of lift, but nothing more.
Anyone any idea where I can look, first, online?
Really hope someone out there can help.

My m&s loafers rubbed my heel on Monday wearing with bare feet but were fine yesterday with tights so hoping I've broken them in (plus just getting back into proper shoes after sandals and trainers all summer!)

I also recommend the anti rub sticks you can get in Boots (with the bluster plasters) for stopping rubbing - kind of like using lip balm but I find it lasts longer
