Earlier today, we brought you the exclusive on the UNION NYC x Nike Dunk High Challenge Supremesneaker, here’s another exclusive for you from Freshness. Above is the UNION LA x Nike Dunk High Challenge Supreme which also released quietly today at the Los Angeles chapter of Union. While the NYC version was inspired by the Hot Lava Air Tech Challenge, the LA version is also inspired by the ATC but not a specific colorway. Unfortunately for most, they are limited to 100 pairs in each colorway and both are already sold out. Other than the color difference, this LA version features LA emboridered into the heel tab.
