Anyone that has sold sneakers on StockX knows the feeling of receiving the confirmation email "Items Arrived at StockX for Authentication," and immediately wondering what rigorous processes and checks are taking place.

StockX's brand is staked on the messaging that products sold on the platform are "100% authentic guaranteed," a claim which is upheld by StockX's in-house authentication team. StockX operates two authentication spaces out of its American and European headquarters in Detroit and outside of London, respectively. We visited the former to speak with two StockX authenticators who explain how they legit-check various products, as well as StockX co-founder Josh Luber, who explains how legit-checking sneakers has become a real career path at StockX.

Luber explains that at the time of StockX building out its authentication team, "You couldn't go to LinkedIn and find sneaker authenticator as a profession, so we had to create it. We created an authentication career path." Part of this process established training manuals, classes and mentorship programs to help employees start as entry-level authenticators, and gradually move up the hierarchy into more senior roles.

Check out the video above for Highsnobiety's in-depth look at StockX's authentication team.
