Though the Cleveland Cavaliers weren’t able to beat the Boston Celtics during Game 1 of the Eastern Conference Finals, LeBron James still managed to rock the hardwood.

King James debuted a new pair of his signature LeBron 15 Nike Basketball sneakers dressed in an-all black Battleknit upper. What makes this pair so special is Nike’s famous “Just Do It” slogan is embroidered on the back of both heels. As a final added touch, the names of James’ children (Bronny for LeBron Jr., Bryce, Zhuri), wife (Savannah), and mother (Gloria) — next to the hashtag #JamesGang — have been personally handwritten on the midsoles. Rumored to be part of Nike‘s upcoming “Just Do It” pack to mark the campaign’s 30th anniversary, look for this pair to hit the shelves soon. So far no release date has been set, but stay tuned for further updates.

In the meantime, take a look at the Nike Air Max 1 “Just Do It” in White, set to drop on Thursday, June 28. LeBron also recently gifted his high school exclusive Nike LeBron 15 “St. Vincent–St. Mary” colorways.
