She's fairly good about not injuring herself. Toes and knees feel pain, so she protects them. Unfortunately, shoes don't, so they are fair game to scrape and tear as convenient. She tends not to kick things explicitly. It's more she does things like trailing her toe up the small wall she's climbing, so she doesn't accidentally kick it.
Shoe quality wise, I've definitely noticed they are nowhere near as robust as adult shoes. The work shoes started out as a complete joke idea. Unfortunately I've still to come up with anything better.
Looks like I need to find the girliest little safety trainers I can find.
