Toss in the wash with cold water. Air dry. Boom.
These shoes were a complete
"These shoes were a complete fail. They are the correct size but the fabric on the top of the heel is super rough. My 2. 5 year old came home with bleeding blisters from the fabric rubbing. Super disappointed. You shouldn’t need to “break in” a children’s shoe. I would not recommend. I am a huge Rothy’s fan for myself but will not buy another pair of children’s shoes from them in fear of this happening again, it’s 2 weeks later and her heels are still working to get better. So disappointing"
