Need White pair of sneakers for travel

Yeah, it's basically for a trip. I want to be able to wear them and make sure I can walk comfortably. Please help your girl out here. I think my budget will be like 6k max.

I want to be able to wear them with dresses and skirts but also walk and stand for the whole day plus light hiking

Also wanted to know should I buy a size up if I want to be comfy ??

Any suggestions will be greatly appreciated
