These shoes fit well. I bought these for my 9th grade grandson and we were concerned the lights would go out in two or three hours. He wore his shoes to the event which lasted 5 hours and at the end of the event the shoes were just as colorful as at the beginning. Many of his friends wanted to know where he bought the "adult" light-up shoes. You plan to buy shoes. As soon as the time changes and it gets dark earlier, they are set up and synchronized during the orchestra rehearsal.
