Good question . . . I've seen these marks on shoes on ebay all the time (and even own two pairs). The two I bought from ebay (Delrays and McAllisters) are in otherwise very good shape. They were "used" so any imperfections I may have just chalked up to normal wear and tear (although both were seemingly very lightly used at the time I purchased them). I do notice that on the Delrays, the right medial forefoot leather where it meets the leather of the outsole is a bit off (as you follow the contour where the upper leather meets the outsole stitching, rather than being 100% smooth contour, there's one small area where it looks like it was stitched slightly off line and the leather "bows" out just every so slightly). Hard to describe, and nothing that really detracts from the aesthetics of the shoe, but perhaps why it was marked as a second (or third or whatever).
