Initial quality seems good and my daughter certainly seems comfortable in them. Good range of movement. I like that the tongue opens completely but I’m undecided if that actually makes it easier to put them on or is more of a hassle. Deducted a design star bc the holes at the front seem like they are going to leave big and pinky toes vulnerable to pebbles and debris.
