The platform-y loafers from Office are great too! Student Engagement role doesn’t sound like you need to veer too far into office/corporate wear. You could wear a more contemporary dress with those boots, for example. I think lots of us on this thread envisioned traditional shift dress when you described a black/navy office dress. Sounds like the sort of role you can express personality in, whilst being neat and approachable.
I think you could wear the boots you linked in your OP, or your existing DMs, just with an outfit that suits them. The cliché be comfortable, be yourself has so much truth.
Good luck with the interview!
