Fashionistas, not strictly designer but I need your help to find a pair ballet flats that don’t destroy my feet!

I have a pair from French Sole, I think they’re the Henrietta style and my god, they rip my feet to shreds. I’ve worn them 4 times now and each time end up with my heels red raw and rubbing around the vamp from the ribbon edging on them - finally accepted that I’m gonna have to sell them and find another pair. Ideally I’d like a pair of Repettos but I can’t bring myself to spend over £200 on ballet flats

(This rationale makes no sense as I have plenty of pairs of shoes that cost much more than that but the price of them seems excessive

)
Anyway does anyone have any recommendations please? Or for any simple black slip on flats?
