I have had several pair of slippers like this, but this is the best ever. It is everything the seller says they are and more. You can barely see that there are Velcro adjusters on each side of the slipper to adjust the fit. The sizing is spot on. The quality is excellent and the support is way more than expected. Hell, I have shoes that are not made this well or that support my feet as well as these do. Buy them, you will be happy with these slippers!!Especially you old guys, like me, the support and comfort on your feet is unmatched. You will probably ware them everywhere, all day long.
