Excellent used condition. They look like they were worn maybe once or twice. Stored in a smoke and pet free facility.
I personally think they are more true to a 7.5 I'm an 8 and I can get them on and zipped up but of course they are too tight. Then again I like my boots a bit snug so maybe they are true to size. I don't have any knowledge or past experience to judge the sizing of jcrew shoes.
It may be beneficial to have a knowledge of this particular brand to assure proper fit.
