Why Izzi got new shoes

Three weeks ago, Izzi got new shoes, which looked like this:
Last week, she came inside complaining that there was a hole in her shoes, and I saw this:

Of course, she had NO IDEA how she got the hole in her shoes. She was certain it didn't happen while she was riding her wiggle car. Maybe she shouldn't ask Daddy to make video's of her so often; she was caught red-footed on tape.

I bought her new shoes. They are absolutely forbidden from going anywhere near the wiggle car, or any other wheeled transportation that may require the dragging of feet to stop.
