BMAI Carbon 4.0 SL (Jingtan 4.0 SL) "White Blade" XRMM005-2 — Carbon-Plate Marathon Racing Shoe
The BMAI Carbon 4.0 SL / Jingtan 4.0 SL (XRMM005-2) is the flagship carbon-plate marathon racing shoe from professional Chinese running brand BMAI (必迈), engineered for elite marathon runners and long-distance athletes chasing personal records. The "White Blade" (白刃破空) colorway features a sleek minimalist white base with aggressive aerodynamic accents — symbolizing cutting through the air like a blade.
Booming-Tech Midsole
Equipped with BMAI's top-tier supercritical foaming compound, delivering over 80% energy return for explosive, propulsive toe-off on every stride.
Full-Length Carbon Fiber Plate
A spoon-shaped rigid carbon plate guides the foot through a powerful forward snap at toe-off, conserving muscular energy over the full marathon distance.
Ultra-Lightweight SL Mesh Upper
The "SL" (Super Light) variant uses an engineered mono-mesh that maximizes breathability while shedding every unnecessary gram — built to go fast and stay cool.
High-Abrasion Rubber Outsole
Provides exceptional grip on both dry and wet racing surfaces, ensuring stability and confidence through high-speed cornering and wet-road conditions.
Sizing & Fit Advice
The Carbon 4.0 SL runs true to size with a snug, performance-oriented fit. True to size is recommended for most runners. If you have wide feet or prefer extra toe-box room during long-mileage runs, consider sizing up half a size.
