"I usually wear a 7.5 or 8 in heels- with this shoe it was immediately apparent that I would need at least half a size larger. I wound up with an 8.5 which has worked out fine. My feet do tend to be pretty narrow but the regular width is perfect for me- so as other reviewers have noted, if you wear a wide this may not be the best bet for you. My biggest issue with heels is the backs digging into what I'm convinced are my weirdly shaped heels. These haven't done that yet, which I think is the biggest selling point for me so far. Other than that, it's a pretty decent, basic pump. It's an easy shoe to walk in if you're not used to wearing heels every day and is versatile enough to use for work or going out."
