BMAI Jingtan Fly

BoomFly TPU Cushioning: Features a full-length aliphatic TPU supercritical foam midsole that delivers a massive 85% energy return. With a lightweight density of just 0.13g/cm³ and a 7mm drop (36mm heel to 29mm forefoot), this thickened platform provides continuous, fatigue-reducing cushioning specifically designed to support you through the later stages of a full marathon.

70D Dual-Tail Carbon Plate: Embedded within the foam is a full-length, integrated 70D solid carbon fiber plate featuring a dual-tail design at both ends. This widened and lengthened geometry helps reduce pressure on the ankles and calves, while a precise 31.8-degree toe spring angle ensures a smooth, powerful forward roll.

Ultra-Light Breathable Upper: The upper is constructed from 45D high-tenacity jacquard mesh utilizing a custom 35g/m² lightweight yarn to maintain its structure and maximize ventilation. Paired with a soft, water-based suede tongue and a built-in internal heel counter, it provides a secure lockdown while keeping a size 41 shoe down to an ultra-light 199 grams.

All-Weather DSP Traction: The bottom is equipped with a 2mm thick DSP lightweight elastomer outsole. This highly durable, wear-resistant material ensures aggressive and reliable grip across a variety of outdoor surfaces, complemented by a widened forefoot last for an accommodating fit and a 3mm TPEE insole for extra rebound.
