Via Onsneaker:
This is a brand new pair of Nike Dunk Hi Challenge Supreme Union NYC. There were only 100 pairs of these made especially for Union NYC. These shoes were released to celebrate Union’s 20 years in the business. This pair best resembles the Andrei Agassi’s Air Tech Challenge. These Nike Dunk Hi’s are accompanied by a Union strap and an NYC stitch on back of the shoe. This pair is extremely limited and will not be seen any where else but Osneaker.com.
