There are sneakers that are introduced through an official press release and others that start making noise long before their release. The Travis Scott x Jordan Jumpman Jack T-Rexx Green Spark belongs to the latter category.
The colorway was first spotted on Travis Scott’s feet during the 2024 NBA Finals in Boston, and the vibrant green immediately led the community to nickname it the “Celtics.” From that moment, nearly two years passed before the final release.
On March 28, 2026, the Green Spark finally arrived on the market with SKU IM9113-300 and a U.S. retail price of $205, adding a new chapter to the first true signature silhouette developed by Travis Scott in collaboration with Jordan Brand.
The debut at the 2024 NBA Finals
The story of the Green Spark began long before it hit store shelves.
Travis Scott was photographed courtside at the TD Garden during the 2024 NBA Finals wearing a pair of never-before-seen Jumpman Jacks.
The setting immediately contributed to the birth of the nickname “Celtics”: the sneaker features a vibrant green that inevitably calls to mind the colors of the Boston team.
At that time, there was no definitive information on the name, SKU, or launch date. However, that simple appearance was enough to turn the colorway into one of the most closely watched Jumpman Jacks in the months that followed.
What is the Jordan Jumpman Jack T-Rexx?
The Jumpman Jack represents an important step in the relationship between Travis Scott and Jordan Brand.
For years, Travis had built his own sneaker universe by reinterpreting existing silhouettes: Air Jordan 1, Jordan 4, Jordan 6, and numerous Nike models.
With the Jumpman Jack, the process changed. We are no longer looking at a classic Jordan modified with colors, materials, or a Reverse Swoosh, but a silhouette developed specifically around the Cactus Jack identity.
The shoe combines references to training, basketball, and skate culture, with a low-top construction, a midfoot strap, and a rugged sole designed to give the silhouette a much more aggressive look than a standard lifestyle sneaker.
Why is it also called the CJ1 T-Rexx?
In Nike communications, the model also appears as the Jordan CJ1 T-Rexx.
The name CJ1 directly references Cactus Jack, while T-Rexx identifies this evolution of Travis Scott's signature shoe.
Therefore, it is the same product family that many sneakerheads continue to call simply the Jumpman Jack.
Green Spark, Vapor Green, and Black
The official colorway combines Green Spark, Vapor Green, and Black.
The dark base creates the primary contrast, while green overlays wrap the toe box, lacing area, and heel.
Nike uses Green Spark leather along with black nubuck accents, creating a surface much richer than it might appear by simply looking at the palette.
The result is far removed from the brown, Sail, and Olive tones that for years represented a sort of chromatic signature for Travis Scott.
The Green Spark is intentionally bolder.
The Reverse Swoosh remains a focal point
Although the silhouette is completely new, Travis Scott maintained one of the most recognizable codes of his collaborations.
On the outer side, there is the large Reverse Swoosh, rendered in a very light shade that contrasts with the green and black.
This is interesting because the Reverse Swoosh is no longer serving to modify a known Jordan. On the Jumpman Jack, it is born directly within a silhouette designed around the Travis Scott universe.
The midfoot strap
One of the elements that immediately distinguishes the Jumpman Jack is the adjustable midfoot strap.
The strap crosses the upper part of the sneaker and sits alongside the traditional lacing system, reinforcing the cross-trainer aesthetic of the silhouette.
On the Green Spark, the strap also becomes one of the main visual elements thanks to the green coloring and the embroidered branding.
The outsole with the "JACK" text
Another detail that has become characteristic of the line is hidden under the sneaker.
The large “JACK” text appears on the outsole.
The branding is designed to be an integral part of the construction and to change visually as the shoe is worn.
It is one of the many elements that allow the Jumpman Jack to have its own identity even without relying entirely on traditional Jordan logos.
When was the Travis Scott Jumpman Jack Green Spark released?
The Jordan Jumpman Jack T-Rexx Green Spark was released on March 28, 2026.
The sneaker was distributed through Nike SNKRS and select retailers in Europe as well, following a long phase during which the release had been generically slated for March.
The definitive details are therefore:
- Release: March 28, 2026;
- SKU: IM9113-300;
- US Retail: $205;
- Colorway: Green Spark / Vapor Green / Black.
Is the Green Spark still available?
The official release has already taken place, so it no longer makes sense to speak of the sneaker as a “super-preview” or a model still awaiting its drop.
Today, availability depends on remaining stock and the secondary market.

Why the Green Spark breaks from the classic Travis Scott palettes
An important part of the colorway's aesthetic success comes precisely from its contrast with what Travis Scott had built in previous years.
Mocha, Reverse Mocha, Olive, Sail, Dark Mocha, and numerous other collaborations consolidated a palette composed mainly of natural tones.
The Green Spark, instead, takes the signature shoe in an almost opposite direction: vibrant green, black, and immediate contrast.
It is a choice that makes the sneaker highly recognizable even within the Jumpman Jack family itself.
The Green Spark and other Jumpman Jacks
The line arrived on the market through various colorways that progressively defined the silhouette's identity.
Versions like Sail, University Red, Dark Mocha, and Bright Cactus show how much the Jumpman Jack can change character through its palette while keeping the strap, Reverse Swoosh, and general construction unchanged.
The Green Spark is arguably one of the most aggressive interpretations precisely because it uses color in a much more prominent way.
The Nike x Travis Scott selection allows you to compare it with the other sneakers that built the Cactus Jack universe.
Why the Jumpman Jack is important in Travis Scott's history
The Green Spark is just one colorway, but the silhouette it is built on represents something much more important.
For years, Travis Scott demonstrated that he could transform already iconic models. With the Jumpman Jack, however, he demonstrates that he can build his own footwear identity.
It is the transition from collaborator on a Jordan to the lead of a true signature line.
This does not mean that the Jordan 1 or other collaborations have become any less important. It simply means that Cactus Jack finally has a silhouette that doesn't have to start from someone else's history.
Why the Green Spark remains a key Jumpman Jack
The Travis Scott Jumpman Jack T-Rexx Green Spark perfectly tells the story of how Travis Scott presents his sneakers.
First, it appears without explanation during one of the biggest American sporting events. Then, it becomes the subject of rumors for months. Finally, it hits the market nearly two years after that first appearance.
In the meantime, the “Celtics” nickname entered the community’s lexicon and the colorway became recognizable even before the official release.
March 28, 2026, closed that long waiting period. Today, the Green Spark is no longer a future release: it is one of the already established chapters of the first true signature sneaker from Travis Scott x Jordan Brand.
