I have limited mobility; hiking is the only exercise I am capable of, and KEEN is the only company that makes a shoe that I can stand in or walk all day. First, the size 10s fit my size 10 feet. 5 / 8 . I use one of these on my main PC. I ordred my normal size, they were huge, so I returned for the next size down. I might try the higher end Liberty Air 2s when they come out which hopefully are more reliable. A bit disappointed since it not the right color but it?s still cute. It was evident that this author had not proofread/edited her work. It may be better to buy another set of £30 headphones for normal music and just use the Audio Technicas for noisy environments. I lost my shoes in Europe and rocked my Teva Mushs the rest of the 5 week backpacking trip.
