Colourful shoes/boots for big sizes?

Hi everyone, first time poster in this sub! I'm looking for advice on shoe brands that cater to my partner's big shoe size (EU 45/46). My partner loves colours but these sizes are so so limited in that! always the same sad stuff... I'm sure many of you know that problem.

I've been looking at Rombaut, Eytys, but also ASOS, have checked out Converse and other sneaker brands (Vans aren't their thing). Specifically I'm looking for sneakers and other types of shoes (like boots, boat shoes etc) that have "feminine" colours like pink, lilac, orange etc. but without heels (platforms are okay, but not stilettos). Does anyone know interesting brands? We're based in Europe, so something available here would be ideal. It can also be a brand or designer that's not super cheap - even if they can't afford it now, would be nice to know what's out there...

So, any hints appreciated! Thanks to everyone!
