I didnt want this silver look to the cross bars. One daughter has a narrow foot, one a thick foot however still both fit in 8. Be aware that they are powered by the USB. The only thing that sucks is I have to take it out of my phone case, but I can deal with it. Perfect fit for hallway and looks sturdy even at the widest part which is the support bar decorative inner ends it doesnt reach 24" the bar itself for towels useable space is 21. It should be on the back side IMO against the wall. Thankful that these do not fill our world with plastic like the other brand. They sound great and are comfortable, come with multi-sized ear tips so the headphones fit snugly and stay in your ears without worrying about dropping. They look cool, seemed comfortable but the straps were tight for a 10.
