I thought an inch difference that I had would be enough to wear them comfortably - it wasnt. But THE SHOES I RECEIVED ARE NOT WHAT IS PICTURED! As long as you have a high lift point that?s strong enough you can do a wide range of lifts that weren?t available to us before. They stay on! The cord is long enough and sound quality is very good - I have no complaint at all. For example, one regular (short) click on "+" skips to the next song, but I would think its more intuitive for that action to increase the volume, which is actually done using a press and hold until you reach the desired volume. I guess I will need to explore other manufacturers now. It took four tries before I found these and they fit the bill. Have been super impressed with these bars. Decided to keep mine.
