My daughter, on the other hand, lives in hers. So much so that she popped a hole in the toe which I imagine in a common problem. At $70/pair we aren't throwing them out until she outgrows them (which will be about 5 minutes). I pulled out the old needle and thread and made a patch that should last until they are too small.
Not much explaining required. I used a denim fabric with stars and just cut the star. If your fabric doesn't have a shape already embroidered like this just make sure it's a thick enough fabric that the ends won't fray.
