This is VERY typical of women's feet and most shoes for women are not made on a women's-specific last. The ones that are would probably fit you better.

Unfortunately, the shoe company I used to work for didn't carry any cycling shoes, so I don't know what brands use women's-specific lasts. You might have OK luck with using a heel cup to reduce the width in just the heel of any shoe, though.

There are LOADS of shoes and if you're OK with parting ways with a good chunk of change, you can probably get something built custom.
