I wear size 11, and the sandal generally fits right. Surprisingly excellent sound quality. Then, magically, without any alteration it just decided to start working correctly. We do go on vacation to lots of warm places, and who wants to wear socks and shoes with dresses everywhere you go?? Not me! I would happily buy I bought these from Ragesolid bit of plastic, 2 cross-head screws attach it to your handlebars. It cleans easily off the smooth surface. Using duct tape over Velcro straps to hold shoes together! When I played music from my MP3 player (at the same level as I would in a quiet room) I drifted into my own little world of Fleetwood Mac. I would order a size larger. Tried on two adults which are so tight they hurt your ears and head.
