The Li-Ning Wind Chaser Pro 2 is a performance-oriented running shoe built around a lightweight woven upper, dual-layer BOOM cushioning, a short carbon-fiber plate, forefoot Jiang technology, and an SGU traction outsole.
Its construction combines layered cushioning with a forefoot-focused support system, assigning different structural roles to the upper, foam layers, plate, and outsole.
BOOM Fiber Upper
The upper uses Li-Ning’s BOOM Fiber construction. A fine woven textile covers most of the forefoot and lateral side, while reinforcement is concentrated around the eyestay, collar, and selected sidewall areas.
This arrangement provides localized structure while maintaining a lightweight and breathable upper configuration.
The forefoot close-up shows the density and orientation of the woven material. Thin synthetic reinforcements are positioned around the eyelets, while the laces connect through a relatively minimal upper structure.
The design avoids extensive padding and heavy overlays, keeping the construction consistent with the shoe’s lightweight positioning.
The tongue and lacing system use a centrally aligned configuration, with additional material around the upper eyelets to reinforce the top section of the closure system.
Dual-Layer BOOM Cushioning
The Wind Chaser Pro 2 uses a dual-layer BOOM midsole. According to the supplied structure graphic, the cushioning system consists of an upper BOOM layer and a lower BOOM layer.
The upper layer is positioned closer to the foot and contributes cushioning and sustained rebound. The lower layer forms the broader base of the platform and works with the upper section to provide continued cushioning across the midsole.
This arrangement separates the foam platform into two functional layers rather than treating the midsole as one uniform block.
Short Carbon-Fiber Plate and Forefoot Jiang Technology
A short carbon-fiber plate is positioned through the midfoot and forefoot rather than extending across the full length of the shoe.
The plate is combined with Li-Ning’s forefoot Jiang technology and a zoned propulsion structure. This system is intended to reinforce midfoot rigidity and support forward transition during toe-off.
Its shape includes cutouts and separated branches, allowing the structural element to remain concentrated around the central and forefoot areas of the platform.
The forefoot component uses an elongated profile with a recessed central opening. It forms part of the structural system surrounding the plate and cushioning layers rather than functioning as an isolated decorative panel.
SGU Traction Outsole
The outsole uses an SGU traction pattern designed around grip, slip resistance, and durability.
Rubber coverage is concentrated across the main forefoot and rearfoot contact zones. The tread uses repeated geometric elements, with segmented sections following the shape of the midsole and forefoot structure.
This arrangement allows the traction layer to remain aligned with the sculpted platform instead of covering the entire bottom surface with one continuous rubber sheet.
Overall Construction
The main structural elements of the Li-Ning Wind Chaser Pro 2 are:
- BOOM Fiber woven upper
- Upper-layer BOOM cushioning
- Short carbon-fiber plate with forefoot Jiang technology
- Lower-layer BOOM cushioning
- SGU traction pattern
Together, these components form a running-shoe platform centered on lightweight construction, layered foam, localized structural reinforcement, and forefoot transition.
Conclusion
The Wind Chaser Pro 2 uses a relatively streamlined exterior to contain a more segmented internal structure.
Its BOOM Fiber upper, dual-layer BOOM midsole, short carbon-fiber plate, forefoot Jiang system, and SGU outsole each occupy a distinct position within the construction. Rather than relying on a single dominant component, the shoe combines upper containment, foam layering, plate support, and segmented traction within one integrated platform.
