PS - I cannot believe how young David Gilmour was. My little one has had tubes in his ears and this is even safe for that ! I have always fit a size 10 exactly (not a size higher or lower) and I felt that these shoes were only slightly small. I ordered the large 10-12. Very nice looking fits well and comfortable. Within a few days the replacement product was on its way. Going to buy longer screws and see if that actually does something. I bought these as a replacement and they are great. I only use them for listening to music at the gym or work, so I dont know about the call quality, but the audio quality is great! My daughter liked the fit better than her Capezio shoes.
