I bought these because they were cute and I needed a new pair of water shoes for the gym (during my kids' swim classes), at the lakehouse in the summer, and on vacation (waterparks, beach, etc.).  I wore them a few times at the gym, barely getting them wet and already the inside sole keeps moving around.  I took them on a weekend waterpark trip and used them to walk around in the kiddie pool/waterpark area and got fed up with the inside soles.  I'm hoping my husband has an adhesive that he can use to keep them in place!
