With shoes on, I'm usually around 6'6" or 6'7". I've never understood why girls are self conscious about height, I wear what I like, I don't see why my height should determine something as arbitrary as shoe choice. My only problem is shoe size. I'm proportionate, and wear a women's size 11 (Like a guys 9.5?), which can be hard to find.
If you don't know already, you can either set a higher bid before hand and ebay will take care of it or there are websites that you can program to bid at the last few seconds.
