Now the only issue Ive had thus far and which has mostly gone away is comfort. I agree with these good customers of Amazon who have had the same experience that I now have. I called their customer service and they couldnt have been friendlier. I think Ive worn them for as long as 2 hours uninterrupted. I love Ultimate Ears. The two prongs are angled upward so objects dont slide off. OMG ! I cant stress enough how comfortable these sandals are. At least theyll know what to expect. After unpacking and removing the tie wires that keep it folded, lay the frame flat on its back with the sides laid flat outward as well.
