Does anyone know where I can get slip resistant work shoes in small child sizes?

I am required to wear slip resistant shoes for work, and I have girls size three feet, but can’t find slip resistant shoes in child sizes anywhere. Yes, there is one child size pair at Shoes For Crews, but they’re too narrow and hurt my feet. 

Please. I really need some help. I’ve been Googling for weeks and can only find adult sizes, and have been talking to companies and they’ve been no help. And I really don’t want to have to just suck it up and deal with a pair that hurts my feet because they’re not exactly the right size.
