Brooks ghost 13 size 5.5

Brooks ghost 13 size 5.5. Gray & lavendar. Bought secondhand for my child, but doesn’t like the purple (pictures when I purchased looked gray & white). Good used condition. Dirty but can be washed (see picture of bottoms of shoe that shows excellent tread and also dirt). Minor wear inside heel from prior owner. We never even tried on after seeing the color. Just trying to recoup what I spent. All reasonable offers considered.
