Before both models release, the Nike Air Zoom Generation Retro “First Game” and “Out of Nowhere” Nike LeBron 14 are available through StockX to raise money for charity.

Dubbed the “Cavs Championship Court SPO,” only 23 pairs of each sneaker will be sold, making a total of 46 pairs available through the “Cavs Court SPO.”

Both shoes will come housed in a commemorative sneaker box crafted from the hardwood of the Cleveland Cavaliers court from their 2015-2016 championship season. A team issued Cavaliers 2016 NBA Championship ring will also be included.

The Cavs Court SPO celebrates the relationship between the Cavaliers and the city of Cleveland’s youth.
