just have to find known sellers on ebay... i use certain stores on there that i trust so have never had a problem... just depends on what you know about shoes as well, someone like myself will know the sort of release quantity and likely hood the shoe will be on ebay... for example jordan 3s are hard to find legit ones on ebay... best time to get jordans on ebay is after they have just been released, as the fakes of that model won't be in circulation as much, fakes of them will come out more so once the shoe is hard to find in stores and is a more wanted release by collectors and your average shoe fan... basically if you dont know your shit go elsewhere
