Even in the house, the floors tire your feet and cause pain. Perfect for a master bathroom. I bought these headphone to use with my chrome book. Looks clean and is nice quality! Active noise cancellation would be a good feature but personally I don?t travel or need to listen to them in noisy environments etc. I usually wear a 9, I ordered a 9, the 9 fits fine, maybe 1mm large (that 1/100th of the length of a cigarette if you are not metric) but maybe not too large, maybe perfect. Keep a repair kit in the boat all times. The smallest size available was a 9, and it is slightly big but still is not a problem. Its probably more hygienic and easier to clean than a leather insole. It was very easy to install and set up with good clear instructions and only took a short time.
