I have bunions so need a W/C or sometimes a WW/D at the forefront but have always had narrow heels even before the bunions. I have found that Ros Hommerson heels don't slip at the heel. In closed toe shoes, I am a 6.5 - 7, and in Ros Hommerson I am always a 7, even if I buy them in wide. Of course, you still have to watch the style so it doesn't cut across the bunion, so not all his shoes will fit or work.
If by *heels* you mean pumps, I think finding a fit will be almost as hard as finding a ballet flat. It took me at least a dozen Zappos returns to find the right Ros Hommersons, and what I ended up with are basic and not fashion forward. If I had my druthers, the shape of the heels on a number of my heeled shoes would be less dated...
Shooties, booties, and boots can stay on with a little heel slippage, so you can get height with those types of footwear. I was thinking that I was limited to W/C widths, but recently found Aldo and Chinese Laundry booties in medium widths that don't hurt my bunions, so now I have three pairs of booties for way less than the price of one pair of Munro booties. Of course, the quality isn't the same, but at this point I need the variety.
