Inspired by the “Devil Blue” anime character, this colourway pairs a green-blue upper with sharp scarlet accents for strong contrast and visual tension.

The design reflects Jimmy Butler’s anti-hero approach on court –controlled, unflinching, and comfortable under pressure. The tougher the moment, the more composed he becomes.

The Jimmy Butler 4 is built for impact players who thrive in physical, high-intensity games. Inspired by Jimmy Butler’s defensive toughness, resilience, and uncompromising competitiveness, the JB4 delivers explosive responsiveness, secure lockdown, and confidence on both ends of the floor.
