I would strongly advice to ride with boots. They don't have to be full on race boots, but even low boots will protect the ankle which is often is injured in crashes and falls.
I don't know if you wife dislikes the height of the footwear or the techie race look, but Icon makes the "Sacred" low boot for women down to size 5, and it looks stylish:
