I am unfortunately very upset with this item. Nothing but junk. Just ordered a second set for my bestie because she fell in love with mines! My feelings are you either wait an indefinite amount of time and save a few hundred dollars, or pay the surcharge to have it in a day or two. So if you are using a magnetic mount or have the phone close to a magnetic field, you will encounter this exact same issue. If your foot is not wide, I recommend go with your normal size. It simply sounds better than any full-functioned multi-channel receiver I?ve owned when used for home theater, which is the way Im using it . Now that a blue one has arrived I put that in the bathroom to use as it was intended. The sole is cushioned, but not too squishy. Very comfortable and perfect lock down attire.
