Is the Mia Abie Mule good for all-day wear?

It is a flat slip-on with minimal cushioning, so it works for short days and errands. For long hours standing or walking, a shoe with more support is a better fit.

Does the open back stay on the foot?

The mule has no heel strap, so it holds by the fit across the top of the foot. It stays on for normal walking but can slip off if you move quickly.

Can I wear it outdoors?

Yes, it is a shoe rather than a slipper. The thin flat sole is best on pavement and indoors, not on gravel or uneven ground.

What outfits does a black mule go with?

Black keeps it neutral. It pairs with jeans, tailored trousers, midi skirts and dresses, and works for office and casual looks.

How does it compare with a ballet flat?

It shares the ballet flat's closed toe and low profile but drops the heel cup. That makes it easier to slip on but less secure than a standard ballet flat.
