I own four pairs of Shape Ups and I bought the Trim Step Fitness version after loving my first purchase of the sneakers. I wanted something that was a little more open, yet supportive, that I could wear to work and casually. Although sporty, these sandals are basically comfortable and cute. What keeps me from rating them with five stars is the slippitch in the heel as you walk (even though I went down a half size than I normally wear). I also have a high instep and by the end of the day, my insteps are sore from the front portion that covers the instep. The velcro strap can be adjusted to improve this, but then it makes the heel slip issue even worse. I am experimenting with orthotics to see if I can't get these shoes to fit perfectly; however, aside from those two issues, the shoes are comfortable for walking and look great with jeans or khakis. Despite my problems, I still recommend them -- just be weary of the heel issue.
