Black tie event, ligament damage - what shoe to wear?!

[FirstTimeHereHello]

Hello!

I have a black tie event in a few weeks, have a navy knee length cocktail dress BUT I have ligament damage following an injury and have to wear a black plastic boot until after the event!

So, I can’t wear heels and wondered if some jewelled trainers or flats (will only be wearing one of them) would work?

If you're in a boot and presumably have a crutch then just wear black trainers and be comfortable. No one will bat an eyelid.
