Bought it for my GF, a size 9. Go play the console stop being such a bottom feeder Shoes were too large. Inspite of the fact that the player was hard-wired to the router, the remote app was still sluggish. I had a Plantronics MLT80 for years, not the same qualities feature wise, but I loved it. I have now changed my mind, cancelled the return , and keeping the belt. After reading the reviews to size up a size or two I thought the 11-12 (smalls) would fit her perfectly. Plugs in and powers up easily, but. I can?t wait to be free if it and benefit from wearing these slippers. For me the main issue is their method to "securely fasten" the shelves.
