The Bzees are amazingly light and comfortable. They're thin and very stretchy, I'm loving the Bzees, but I wanted to review them to point out an important difference between the syles within the line. There are many types of Bzees on Naturalizer right now and I've purchased 3 of them. My experience is that they vary in width dramatically. I sometimes have trouble finding wide shoes wide enough for my feet, but the no-fastener Bzees called Summer Fun are WIDE -- I almost don't feel like I'm wearing shoes! The zippered Drive Ins were slightly too snug when I first put them on, but they loosened up after a few wears and are just a little snug. The laced Dash style is the narrowest of the 3 that I purchased, and I'd almost call them a regular width, even though I confirmed that I did indeed receive the wides. I kept the Dash and will continue to wear them because the material is so stretchy that I can, but I foresee wear issues in the seams closest to the widest part of my foot and around my pinky toe. So, to summarize, widest to narrowest: Summer Fun, Drive In, Dash.
