Heh! Good question!
The shoes should be screaming 'practical'... low, chunky heel, laced up front, rounded toes.
The closest thing I could find off-hand is from an outfit by Teyon https://www.renderosity.com/mod/bcs/nun-outfit-for-genesis-3-female-s-/114701</https:>
But that outfit is for the Gen3 females, not Victoria. I don't know how well you can convert shoes from G3 to V4.

There are some nice reference images here:
