I already had several of these in different colors so I knew which size to go for. I bought these for my friend's wedding who had a Doctor Who theme and was gracious enough to let us bridesmaids wear them to the reception instead of the killer heels that turned our toes purple! They were much more comfortable and looked great. I love wearing them now! You can't beat a pair of black Converse.

The first pair of cartridges. I read reviews that they are a bit long for their size. I wear 10 and ordered 10. They fit great. It's the shape of the toe box that makes them big. You need room for your fingers to spread properly. If you have doubts about the size, I recommend trying them on in store first and then ordering online. They also accommodate the insole very well for those of us with flat feet who need extra support.
