All fun and games until you need to take them off. They work okay, but I need to take them off and cannot unlock the clips that go on the end of the laces. I contacted the company and they said I need a SCREWDRIVER to get them off. My husband and I both tried and we cannot get them off. So, now I will have to cut them off and cannot use them again. Beware this issue. Incredibly poor design. Would not recommend.
