These shoes are not only nicer looking than the original Shape-Ups, they are soooooo much more comfortable. They are very lightweight (not nearly as heavy as originals), incredibly cushy and comfortable- a natural feel even better than walking barefoot- and the look cool too. They are lower profile and not as thick/tall as the originals. I LOVE them and would definitely recommend them to anyone! You can feel your calves & ankles working, but not uncomfortably so. My feet have never been happier- Thank you, Sketchers!
