Jimmy Choo black mesh heels size 37

These are a beautiful pair of Jimmy Choo London high heels that I originally bought from another posher. I have learned that no Choo fits exactly the same! This 37 is a little tight for me. It would fit a size 6 best. I normally wear a 6 1/2 and while my foot can fit into these, they are too tight. These are in excellent condition, the heels are pristine, there is some normal wear on the soles.
