I bought this shoe originally in a size 10, my normal shoe size in just about every brand. The 10 was way too big to wear without socks or with thin hosiery; the back flopped off when i walked. So, i exchanged for a 9.5. The 9.5 is perfect in length and does not slip off my foot at all when I walk, yet I have toe room...but (here's why I gave them 3 stars)....the front of the shoes pinch my foot pretty bad right at the base of my pinky toes. I actually have them off my feet right now in an attempt to relieve the pain a bit (I wore them to work for the first time today). I'm hoping that if I wear them a few times they will stretch a bit and break in. The soles of the shoes are very comfy and add a little bounce when I walk which is quite nice...much like walking on little pillows. The inside is also a very soft, suede like material which is very comfortable without socks in warmer weather. They look very cute, yet professional for work. I will update this if they do eventually break in and the pain at the base of my little toe goes away. :)

*Update*
I originally gave this shoe 3 stars, but I've now changed it to 4 stars. I used a shoe stretcher to stretch the part that was originally causing me pain and they are great now. No pain, no rubbing, no pinching. I wear these without socks (just my preference). They are quite comfy, practical, cute and perfect for work. I really like the fact that they have a rubber type sole so that they don't clickity-clack when I walk down the hallways at work! I did not give them 5 stars just because they are not, in my opinion, the "best" shoe...but good nonetheless. :)
