There is tons of stuff see at ComplexCon and it will literally take every hour of the day to walk the floor to dig through everything and sort the cool from the less-cool. You'll have to REALLY pick and choose what it is you want to "hypebeast" over and get to the line at the booth of choice and be prepared to wait.
One of the coolest (and profitable) attractions was at Adidas where they sent attendees on a hunt for tokens to enter a lottery. Prizes comprised of a large number of super-rare sneakers—including Kanye's newest. The first pair was valued at $2500.
