Either tie them in place as if it was just a rope or replace them with a buckle strap (think heavy duty version of a backpacks strap buckle) or a ratchet strap. They are very well made. the fake wood was deformed and not smooth as the picture leads you to believe. Lovely birthday gift, my daughter was very pleased with it ?? not having to plug in her iPhone 8 in with Apples awkward Lightning Plug charger! Working as intended! So, why did I end up buying another pair? Two answers to that. I was very pleased with the quality and comfort. We did not get any hassle with the return however. 99 to $69.
