Dopo qualche giorno occorre stringere di un foro . Dont buy this if you are at all sensitive to odors or just dont like toxic chemical laden products near you or your family. They fit well, they feel good on the feet and dont loose their shape too much. I finally bought a grey pair because I kept forgetting to take off the bright orange ones before I left for work! Overall great product and a very great value! They are not as loud as my Bose over the ear headphones and I did not expect them to be. UPDATE: 7/9/19 *TWO OF MY STRAPS JUST BROKE TODAY AFTER GETTING CAUGHT IN THE FRONT DOOR OF MY HOUSE LITTLE UPSET BUT ITS AN EASY FIX PAID A LOT OF MONEY FOR THESE FLIP-FLOPS TO HAVE THEM BREAK SO EASILY AND THEYRE MY FAVORITE PAIR TOO! This was my first time buying a dance product from Amazon. Special thanks for the CEO for going above and beyond for a single customer. This coat rack is nicely designed, however, the craftsmanship was so bad I had to have mine replaced.
