No issues with ankle strap being loose. Brought these for my mother as she has arthritis and her feet swell a lot. These are the most practical kids sandals I?ve bought. Ha anche una protezione per il foro di ricarica. The only downfall is they do have a little stretch with the strap in the back. Ich bin bisher sehr zufrieden mit ihnen und das wichtigste, Musik abspielen und Telefonieren können sie perfekt. You open the box and are greeted with a small black plastic box containing the headphones, as soon as you open it they are ready to pair with whatever device you wished. Also, for anyone that has limited mobility in their hands, such as arthritis this item will be very difficult to fasten. They look and fill just like my Ugg slippers, just cost a third of the Ugg price. My daughter was between a 7 and 8 in regular shoes and the 8s were pretty snug.
