I normally wear a size 9 and I purchased this shoe in both a size 9 and 9.5 after reading on Zappos that 75% of customers thought the shoe ran 1/2 size small.  I found that it was very true to size and the 9.5 was too big.  In addition to this style, I've also tried the Skechers Optimize and Skechers Metabolize.  Of these three shape-up styles, I prefer this one the most.  The main reason is that this shoe has mesh panels on the sides, so my feet don't feel as hot or confined in the shoes.  The other thing that I like about this shoe is that the material is easy to wipe down.  With the other styles (think beige nubuck leather), I was concerned about getting them dirty and having a hard time getting stains off that type of leather.

Finally, I purchased this shoe in the mocha color, which I first had reservations about.  I really don't care for brown and try to wear as little of it as possible.  But it is more of a bronze shade and I think the picture on Amazon makes it look more brown than it really is.  The most noticeable brown is on the squishy part, and it is actually darker than portrayed in the photo and looks much better in person.  These shoes are very pretty and stylish and I'm happy with this purchase.
