I noticed many reviews all over the place about recommended sizing.  I think it may have to do with which color you choose.  I bought the Color: Blue (Stylish) in a size 7 and they fit really well but have a little more room in the width than I prefer.  I have a narrow foot.  I consistently wear a size 7 in most shoes.  Since I am giving those to my sister I decided to buy another pair for myself.  I bought the Color: Green (Stylish) in a size 6.5 and a size 7 to see which would fit best.  I found the green ones to be huge.  I tried on the 6.5 first and they seemed more like a size 7.5 or 8.  I then tried on the green (stylish) size 7 and they were big also, maybe by a half size.  I returned both green pair.  I then ordered another pair of the Blue stylish in a 6.5 and 7 because of the inconsistency with sizing and I need them by Fri.  As it turns out the blue (stylish) seems consistent with sizing.  The 6.5 feels tighter in the width which I prefer but the length is border line too small.  The 7 fit just like the first pair of blue (stylish) size 7's I bought.  They are very comfortable as everyone else has stated.
