After wearing them for almost an hour, the back strap slides down my heels. The heel is not too high. Very pretty but the run small Estos zapatos me demostraron que estaba equivocada. This is a fun item but the quality is low. With a pencil mark where the holes are on your wall. it has solved the messy pile of shoes in the hallway problem! 1) in Windows. I am very happy with the quality of these headphones and would recommend them to anyone looking for more intuitive pair. I like the organized look and feel.
