Jordan Flight the Power PROD CFM SAMPLES?

I just picked up a pair of Jordans online from Goodwill. When I got them I noticed that the tag said Prod CFM sample on it. Also, there is pen writing on the inside of both heels that says "prod cfm Alex Shen? 11/24

Any help I can get on these would be great. I am not a Jordan nut, just got a good deal on these and thought they looked cool. I have not been able to find anything about them online.

That looks like a sample tag...that is all I know about the shoes.

I have seen some online that say Sales sample, but not Prod CFM sample. Do you know what CFM stands for? and why would someone write on the heel, I guess it is some kind of quality control or something. So do you know how these would get out into the public? Any idea on a value?
