There is no sleeping allowed on the JA 4.
Ja Morant’s latest signature Nike Basketball shoe enhances his on-court performance by providing superior support and responsiveness. Featuring a Cushlon 3.0 midsole for confident drives to the basket and an upgraded JA-Frame containment system for optimal security during cuts, this footwear is designed to elevate players’ agility and stability.
The fourth silhouette in Ja’s signature Nike Basketball line enhances the exceptional originality and performance of the JA 3, delivering dynamic energy to support Ja and other underdog athletes at all levels of play.
“That’s something we really started building with the 3, and seeing how it evolved on the 4 is crazy,” says Ja. “It just feels more raw, more aggressive, like it’s got more attitude to it. That’s what I like. It’s one of those details where if you know, you know. And for me, it just represents how I’m evolving too.”
When designing the JA 4, Ja aimed to create a shoe that reflects his personal style—supporting his dynamic and explosive gameplay. This begins with the signature JA Swoosh, which has been reimagined with enhanced functionality in the JA 4. Ja’s distinctive vertical Swoosh is complemented by a lightweight TPU JA-Frame that encircles the foot, providing stability and security for players as they move, shift direction, and make decisive plays.
The TPU JA-Frame is designed to collaborate seamlessly with a responsive Cushlon 3.0 midsole and a lightweight SPRPWR sock liner made from supercritical foam. This combination provides support, enhances energy return, and promotes durability—allowing Ja to perform at a high level, recover efficiently, and remain prepared for the next opportunity.
A precise traction pattern enables Ja and other basketball players to plant firmly, navigate pressure, and drive toward the basket. Additionally, foam ridges along both sides of the silhouette provide essential durability and protection to support the intensity of Ja’s game.
Personal design elements enhance the shoe’s appearance, including Ja’s signature logo and his former jersey number, which pay homage to his Twelve Time Basketball program. Inspiring quotes are featured on the outsole (“If you’re down there, you’re in the way”) and the medial upper (“I don’t have motion where my feet at — it’s global”).
Furthermore, the Nightmare launch colorway highlights why Ja’s dynamic playing style continues to challenge defenders and leaves opponents constantly on alert.
“Colorways have always been big for me,” says Ja. “I don’t like playing it safe — I want my shoes to stand out, just like my game. Every pair gotta have some energy to it, something that makes you feel different when you put it on. I pull inspiration from everything: my life, my mood, my family. And yeah, I’ve been hearing people call me the ‘Colorway King,’ so I take that serious. I’m gonna keep making sure every drop hits like that.”
The JA 4 recognizes Nike’s unwavering dedication to supporting the athletes at the heart of the sport. Through collaborations with a diverse range of top-tier veterans and emerging stars, Nike is shaping the future of basketball—developing exceptional products for the best, and delivering them to those who are most passionate about the game.
“As Nike Basketball continues to look for new and innovative ways to serve Ja and his consumers, we always start with the athlete first, asking the right questions that give authentic insight into what the specific needs are to perform at the highest level on the court,” says Monique Currie, product line manager for Ja’s signature footwear. “In addition, we want to stay true to the edge and expressiveness that Ja embodies both on and off the court, ensuring that when a player puts on a JA 4 they are confident in their performance and ready to attack.”
JA officially unveiled the silhouette as top emerging basketball players from Nike’s Elite Youth Basketball League showcased their skills on JA-branded courts in Las Vegas, reflecting JA’s dynamic style of play and self-expression. This event coincided with the NBA Summer League competition in Las Vegas.
The Nike JA 4 will be available globally August 13 at nike.com and select retail locations.
