Okay, so let me start by saying I have several pairs of T.U.K. shoes in this exact style (just different colors) and I have always worn a size 6 with no problem. So when I saw these cuties on sale with a size 6 in stock...I pounced. I was so sad when I got them yesterday and tried them on. They were way too tight in the instep and a little short in the length. The really weird thing was that the left shoe felt even smaller than the right. These are so cute that I considered trying to stretch them somehow but they are manmade materials and I just think that there is no way I'm gonna get them to fit without extreme pain. Other than the fit issue, these are so adorable. The red is very vibrant in color and the little velvet bow on the kitty ear is beyond cute. Also the little kitty ears themselves sit on top of your foot giving it a very 3 dimensional feel. One other thing of note though is that the white polka dots are painted on the shoe, and a good majority of them on one of the shoes I got were either rubbed off or never painted on well to begin with. I really wish T.U.K. made 1/2 sizes as I think a 6 1/2 would fit perfectly. So with the fit issue and the polka dot issue I am going to have to send these back. Unless you have a very narrow foot I would suggest going a size up.
