Help! How can I clean my daughters shoes?

They’re insanely dirty!!! I always keep her things in good condition but she went to my in-laws and this is how they came back...they didn’t even say anything about it 😒 they looked brand new when I sent her...so annoying!

I was thinking of putting them in the wash, but I’m worried they’re going to get ruined...any ideas? I wanted to pass them down to her brother
