After taking these out of the box and trying them on, they are probably the most comfortable shoes I've ever worn. It's tough to find size 15 that look and feel good, so I was excited. Feels like you are walking on air. After about three months of walking on the treadmill 3/4 times a week (torn acl, so I couldn't even run) they tore in the heel. Amazon sent me another pair, and now the same thing has happened again, even quicker. These shoes have minimal mileage on them, and have gone through two pair in less than six months. Very disappointed, would not recommend especially for the price.
