Qiaodan Feiying Plaid 2.0 | Elite Carbon Plate Marathon Racing Shoes

Introducing the Qiaodan Feiying Plaid 2.0 – the 2025 flagship elite racing shoe from Qiaodan Sports, engineered for serious runners targeting sub-3:30 full marathon finishes. As the 3rd generation of the Feiying Plaid series (2023 1st Gen → 2024 1.5 → 2025 2.0), it delivers a complete overhaul in materials and structure, combining 100% PEBA supercritical foam, a performance-tuned carbon plate, and race-ready stability to redefine speed for high-cadence runners.

Designed for athletes with a cadence of 185-190 steps per minute, this shoe excels in marathon races and high-intensity training (intervals, tempo runs). Its 95% energy return, 0.2s quick rebound, and reduced energy loss (4% lower consumption) make it a game-changer for late-race sprints, while the upgraded stability features eliminate the drawbacks of previous generations. With a competitive price point vs. international flagship racing shoes, the Feiying Plaid 2.0 offers elite performance without the premium cost.

Core Technology & Performance Highlights

* Q-KUNGFU PRO-HP Supercritical Foam Midsole
100% PEBA supercritical foam (upgrade from Plaid 1.5’s TPEE):
    * 95% energy return + 0.2s quick rebound for "instant push-off" responsiveness.
    * Ultra-low density (0.07g/cm³) – 8% lighter than predecessor (206-208g/US9).
    * Exceptional anti-fatigue: Maintains elasticity beyond 30km, ideal for the second half of marathons.
* 
* Full-Length Shovel-Shaped Carbon Plate
Parameterized carbon plate with reinforced ribs, optimized for runners' gait mechanics:
    * 14% improved torsional rigidity for stable foot strike.
    * Aggressive forefoot curve enhances propulsion efficiency, reducing push-off force by 9%.
    * Extended rolling arc minimizes ankle valgus risk during high-speed turns.
* 
* Q-ASU Anti-Slip CPU Outsole
CPU racing rubber + hydrophobic hollow tread pattern:
    * 50% more wear-resistant than traditional rubber; 800km+ lifespan.
    * 25% improved slip resistance (0.85 wet grip rating) for rainy or wet pavement.
    * Zoned tooth-like tread enhances traction across different terrains.
* 
* Gongsi PRO Upper
55% PEBA yarn blend + one-piece stretch sock-like design:
    * 16% higher tear resistance for durability during intense training.
    * Adaptive fit with integrated tongue; rear heel counter prevents heel slippage at high speeds.
