It is one thing to be inexpensive, another to be cheap. If you plan to use these with an iPad Pro or other device which has a USB-C port. I was replacing a very old pair of FitFlops that finally broke, so I knew to order a half size smaller than I normally do. Ordenar una talla mas. The first time I put them on I found them to be a tad too big in the heel area and flopped a bit. But when I wear the one I bought (perhaps more later) Im glad I splurged on this as it feels so wonderful with not gathering/bunching/binding problems that other brands had. Of all the devices Ive had experience with, this device is "top notch. While it makes it easy to rotate it means the mount is not as sturdy as it could be. I like this waist trimmer/sweat belt. True to size, don?t slide on the gym floor, and super comfortable and well made.
