The Nike Ja 4 “Halloween” pairs torn Oil Green layers with Bright Crimson accents and a glow-in-the-dark green outsole under style code IO7939-300. Reports point to an expected launch in late October 2026, with 23 October noted in one report and October given without a day in another. Nike has not confirmed the exact date.
The exact catalogue profile for this seasonal basketball model:
Product
Distressed green layers across the upper
Layered textiles cover most of the upper in dirty green and olive shades. The meshes change from panel to panel, so the surface is not one flat fabric. Dark grey mixes into those greens, adding shadow across the forefoot.
Brown sections sit on the opposite medial side and around the heel collar. That dark tone makes the back of the shoe deeper than the olive toe box. Faded graphic marks run across the side walls to complete the worn look.
Torn edges break each layer rather than following clean cuts. Olive laces secure the tongue and match the interior collar lining. Those green elements establish a dark base before the sharp accents take over.
Bright Crimson support accents
Bright Crimson provides the primary sharp contrast against the murky green upper. The shade covers the oversized lateral Swoosh across the side wall. It also fills the sharp JA midfoot support piece embedded into the midsole.
That vibrant finish stays confined to the branding marks and midfoot component. Concentrating the vivid colour on structural accents keeps the rest of the shoe grounded in muted olive and charcoal hues.
Seasonal hardware and footbed graphic
This Ja 4 includes a moulded fang lace jewel threaded onto the throat. The hardware detail previously appeared on earlier seasonal models in Ja Morant's signature footwear series. It sits over the olive tongue beside frayed fabric overlays.
Underfoot, the outsole uses translucent green rubber engineered with a glow-in-the-dark finish. The base illuminates with a bright green tint under low light, continuing the theme to the bottom traction surface.
Inside the collar, the insole carries a full-colour graphic showing Ja Morant shouting. The print replaces standard minimal footbed text with an expressive illustration tied to the seasonal theme.
Design lineage and seasonal placement
The Ja series serves as Ja Morant's signature line with Nike, engineered for low-profile court performance and fast direction changes. Successive models have maintained a low cut while retooling upper support and panel layouts.
Compared to earlier seasonal releases that relied heavily on printed monster motifs, this pair leans on physical material distressing. Frayed hems, differing textile gauges and the moulded lace fang establish the seasonal theme through tactile construction.
The colourway name combines Oil Green, Light Lemon Twist, Black and Bright Crimson. These named tones sit alongside the specific visual details: olive and grey fabric, brown sections, crimson marks and green rubber underfoot. The result reads as a Halloween pair through its worn surface and low-light detail, rather than relying on one large printed graphic.
The layered upper gives this edition a different emphasis from a colourway built around a clean, uninterrupted panel. Its ragged edges and varied textile surfaces make the green base look irregular across the shoe. Bright Crimson then draws the eye to the Swoosh and JA support piece, while the glow effect moves the seasonal detail below the foot.
The reported release timing ranges from an October 2026 window to a specific 23 October launch. Nike and select retailers are the expected sales channels. Treat the day as provisional and check the retailer's launch details before planning a purchase.
The pair is the fourth signature model in Ja Morant's Nike line, following three earlier numbered shoes. That sequence gives the seasonal colourway a clear place in the model family, but the release story here centres on its surface treatment and Halloween accents. For buyers, IO7939-300 is the useful identifier when checking that a listing refers to this exact green pair.
The catalogue match identifies an adult version and provides a usable product photo for the exact style code. That helps separate this shoe from other Ja releases with Halloween themes, including the Ja 3 “Zombie”. The colour and code are the practical checks to make before following a release listing.
