An update, for honesty's sake: I bought the shoes, but due to a mistake in the sizing options, I got a pair that was much too small, and returned them. In one of my first practical cases of avoiding sunk cost bias, I didn't reorder them or try to get my daughter to wear them, but took the loss of the shipping charges (not refunded) and bought a set of boots that were on sale and much more practical for my line of work, and used the extra money I would have budgeted on the shoes for ergonomic value into buying a set of Chinese relaxation balls, which, mumbo-jumbo aside, do relax me and stimulate the nerves. So, I use them when watching TV or when idle, once a day. I save time by playing with my balls instead of just playing wi--well, you get the idea.
