How knowledgeable are you when it comes to the sneakers of the Brooklyn Nets?

The franchise wants to know, and it's giving away a pair of tickets to anyone who can identify which player on the squad wears the Freegums x Nike LeBron Soldier 9 shown here.

What's cool about the giveaway is the team's inventive use of social media, which involves rotating players on the top half of the Vine video announcing the promotion. To enter, followers pause the Vine on their guess, screenshot it, and reply.

See the contest below if you're in NYC and maybe take a look at our #SoleWatch column for hints.
