Nike Ja 4 Nightmare – Men's Lifestyle Shoe | Obsidian/Black/Voltage Green/Metallic Silver

Built for the Nightmare.

The Nike Ja 4 Nightmare in Obsidian, Black, Voltage Green, and Metallic Silver is the men’s colorway that channels Ja Morant’s most electric, high-voltage on-court energy into a four-color palette that hits as hard as his game. Deep Obsidian and sharp Black create a dark, commanding foundation while Voltage Green explodes across the silhouette with the kind of neon energy that makes you impossible to miss — and Metallic Silver adds the precise, premium finishing detail that separates the Nightmare from every other colorway in the Ja 4 lineup.
