Nasty Gal Platform Biker Boot Black Size 8.5

I ordered these Size 9 boots and they are VERY small on my feet so I was never able to wear them. I’m listing them as an 8.5 because of this! The bottom of the shoe says Size 7, which the Nasty Gal representative assured me was the UK Equivalent to US size 9 (Nasty Gal is a UK company). I did a google to check this info and it is correct. These are brand new and not available on the website!
