Fake -this CW doesn't exist for the Alpha Trunners
I searched all the legit sites to find this particular colorway -PYS, Nice Kicks, Sneaker Files and of course Jumpman23 ...NONE of those sites had this listed as a CW from the past couple of years that the Trunners have been retroed.
I did however come across this exact CW on nearly every fake site out there -add to this, the site you linked also sells fakes.
