QIAODAN Feiying Plaid 3.0 "Cirrus Blue / Pure White" QDB023262290 - Marathon Racing Shoe Unisex Blue White

QIAODAN Feiying Plaid 3.0 "Cirrus Blue / Pure White" QDB023262290 — Elite Carbon-Plated Marathon Racing Super-Shoe

The QIAODAN Feiying Plaid 3.0 QDB023262290 in Cirrus Blue / Pure White — also known as the "Horizon Sky" colorway — is Qiaodan's 2026 elite carbon-plated marathon racing super-shoe. Engineered as a high-propulsion race weapon for competitive long-distance runners pushing for new personal bests in half and full marathons, the Horizon colorway flows from a crisp pure white heel into a serene cirrus blue across the midfoot and toe box: clean, fast, and built for the podium.

🏃 Design Concept

• "Horizon Sky" Palette — A sleek, high-velocity gradient flows from crisp pure white at the heel into serene cirrus blue across the midfoot and toe box.
• Max Legal Stack Height — Race-legal maximum 40mm heel / 33mm forefoot stack with a 7mm drop that keeps every stride biased toward forward momentum.
• Weight Elimination — Full chassis trimmed to approximately 185g–188g (size-dependent) for featherlight leg turnover across 42 kilometers.

⚙️ Performance Breakdown

• Triple-Density PEBA Cushioning — Three distinct density layers of supercritical Q-Kungfu PEBA foam: a soft step-in layer directly underfoot, a firmer base layer for stable landings, and a super-squishy Kinetic Core forefoot pod that acts like a high-compression trampoline piston at toe-off.
• Suspended Forked Carbon Plate — A full-length, high-stiffness carbon plate floats between the foam layers and splits into independent prongs at the toes — allowing natural foot articulation while creating a snappy, forward-rolling forefoot rocker mechanism.
• Bootie Comfort System — Integrated high-lockdown knit tongue and elastic bootie collar, with expanded monofilament mesh ventilation windows that continuously expel heat and reduce blister risk over long-distance efforts.
• Segmented Q-ASU CPU Outsole — Multi-segmented liquid-cast CPU rubber mapped only to high-impact wear zones delivers a wet-surface friction coefficient of 0.9 while extending tread durability to several hundred kilometers.

📏 Sizing & Fit Advisory

• True to Size — Highly locked-down, true-to-length performance hug with excellent midfoot containment and zero heel slippage.
• ⚠️ Low Toe Box Volume — The vertical volume ceiling directly over the toes is quite low-profile.
• Thin to Normal Feet — Stick to your true standard US size for a perfect 1-to-1 racing fit.
• Wide Feet or High-Volume Arches — Size up half a size. The entry ankle bootie collar has limited stretch and the low-volume toe cap will heavily pinch wider feet over high mileage.
