Li-Ning Jimmy Butler 4 "DRK" ABAV089-25 - Basketball Shoe Unisex Black
Li-Ning Jimmy Butler 4 — "DRK"
The centerpiece of Jimmy Butler's fourth signature line, the Li-Ning JB4 DRK (ABAV089-25) is engineered for aggressive wing players, slashers, and physical defenders. Structurally built to manage elite-level athletic impact, it focuses on raw torsional rigidity, maximum lateral containment, and vertical launch assistance — behaving like a high-performance roll cage for your feet.
Design Concept
The "DRK" colorway features a stealthy, futuristic all-black silhouette with subtle contrasting white and metallic undertones. It embodies Butler's "Silent Dominator" persona — dangerous, low-key, and relentless on the court. Sculpted wave paneling across the upper mimics tactical armor, mirroring the intensity of a player who thrives in high-stakes defensive lockdowns.
Performance Breakdown
- Carbon Core Drive System: Full-length Li-Ning BOOM nitrogen supercritical foam stacked with an encased, curved carbon fiber plate. Lab-tested to enhance vertical spring efficiency by 3.8%–4.1%, easing explosive strain during jumps and hard push-offs.
- 3D IBR Lockdown Upper: Three-piece Injection Breathable Rubber (IBR) frame structurally mapped over a mesh center. Creates an "octopus-like" lateral wall that stops foot spill and sliding during hard step-backs and heavy contact drives.
- GCU Ground Control Outsole: Full-length Ground Control Unit (GCU) rubber with a multidirectional traction grid. Delivers an immediate stop on hardwood with 13% higher slip resistance and 5% better raw durability than traditional solid rubbers.
Sizing Advice
- Narrow to Normal Feet: True to Size (TTS). The molded heel cup and explicit side panels provide an unshakeable 1-to-1 fit with no internal dead space.
- Wide Feet / High Insteps: Go Half a Size Up (+0.5 US). The structural IBR side walls do not stretch or break in over time — wide foot types will experience extreme side pinching if they stay true to size.
