Li-Ning x NINEPointNINE Feidian 6 Ultra "Milk White Rubble Gray" — Style Code: ARMW015-4

A limited-edition high-fashion collaboration between Li-Ning and designer label NINEPointNINE, the Feidian 6 Ultra represents Li-Ning's absolute highest tier of competitive running technology wrapped in a minimalist streetwear aesthetic. Built purely for chasing personal records — note that its forked T1000 carbon plate design renders this shoe non-compliant with World Athletics regulations, making it a dedicated PR machine for elite training and open-road racing.

Design Concept

• Aesthetic Minimalism: A clean, sophisticated Milk White and Rubble Gray palette with sleek metallic silver paneling — a deliberate departure from typical marathon neon gradients.
• High-Fashion Fusion: Co-designed with NINEPointNINE, featuring intricate paneled constructions and embossed collaboration branding on the heel. As sharp on the street as it is on the race course.
• Stripped-Back Craftsmanship: Deconstructed booty-style build with an integrated stretch-knit tongue, thin collar lines, and subtle geometric panel motifs throughout.

Performance Breakdown

• Quad-Core Power System: Full dual-layer stack of premium Super BOOM race-day foam combined with an encased, pressurized supramolecular polymer Super BOOM Capsule — delivering an explosive 95% energy return with a rapid 3ms bounce response.
• Forked T1000 Carbon Plate: Asymmetrical top-grade T1000 carbon fiber plate that splits into separate planes at the forefoot and rear. Violently snaps back during linear acceleration for elite propulsion — optimized for aggressive forefoot strikers.
• BOOM FIBER Upper: High-tensile single-layer monofilament polymer weave that is 35% more breathable than traditional mesh. Total shoe weight: 193g (US size 8).
• GCU Ground Control Outsole: Soft, incredibly sticky Ground Control Unit rubber grid delivers unparalleled traction on both bone-dry and rain-soaked asphalt racing roads.

Sizing Advice

Length: True to size (TTS) with an anatomical toe box and ample wiggle room. Midfoot Lockdown: Dynamic cable-and-eyelet overlay network pulls tightly around the foot for a zero-slip fit despite stripped-out heel and collar padding.

• Narrow to Normal Feet: Order your standard US running shoe size for a glove-like competitive fit.
• Wide Feet & High Insteps: Order half a size up (+0.5 US). The BOOM FIBER upper has high-tensile strength and very little lateral stretch, which can pinch wide feet over double-digit mileage.
