I have a pair of dancing sneakers that I've owned since college and haven't used at all since graduation. They have hardly been used at all, in fact. In women's sizes they are a size 10 (yes, my feet are ginormous), but they are unisex shoes. They run about 1/2 size big for women and 2-2.5 sizes big for men.
In case anyone is interested,
this is what they look like (with red laces, woo!). I'll pass this on for free +shipping to anyone who would like them. Just leave a comment for me if you are interested; first come, first serve.
ETA: The sneakers have been spoken for :)
