I am thinking early day UAs. The shape is too good to be a chinese fake from that time period. The inner tag is suspect. Carbon Fiber plate as well. But yeah the shape , heel, other areas check out. As far as a retail pair....- there was never a silver/navy made in vietnam pro.. It is a size 9 , but no sample stamp, marker, or even style code or manufactuer date on the inner tag. even my early 2000 pairs had manufactuer dates.. And even samples have some sort of style code , even if its just 99999999. It has a hand written code that doesnt even follow nikes coding. At the end of the day, I cant say these are samples.. Cant say its fully legit either.. UA is my best opinion. i dont keep up with new releases, but this isnt a new release.. factories switched from taiwan to china , I think after the pine pros released.
