Listen, unless youre a musical prodigy who ONLY has the BEST of the BEST audio equipment and likes to spend HELLA money on top line overdone products, then this speaker will blow you away. So I haven?t had the chance to wear them yet as it is winter lol. 5" apart and I still had room to spare. 5 a size. These seem to be wide, not sure about people with narrow feet? These are very similar to those shoes, retirees wear, however these are very comfortable, however these are much more comfortable vs the ones mentioned, which are typically very narrow and typically have very thin soles and are very uncomfortable, especially if you are doing a lot of walking. If I had to pick one pair of shoes to walk around the world in, it would be a pair of Merrill?s. We recently purchased a new home and thought this would be perfect near the front door. And, in an unexpected bonus, it matched my case. They have held up very well though. It has helped my back when doing workouts and the material to help you sweat is just an extra plus on it!
