I have narrow feet but they still fit me nicely. I dont know if those lights can be turned off. My original pair of shoes are no longer available so I decided to try this brand and style. These shoes are so cute, but didnt work for my feet (which are too narrow for most "wide" sizes but are sometimes too wide for mediums). Biggest pet peeve, til I realized they sell these bad boys separately ?? Life is good. A great basic! Its easy to install and appears rugged. On my feet all day and these feel so good after getting out of my steeltoe boots for over 10 hours a day. I use them every singe morning at gym. All of the fancy talk about streaming music all over your house is ONLY for music that the System IV gets via the app or via a bluetooth connected device!
