The Li-Ning Feidian 5 Challenger "Black White" is a lightweight, carbon-plated racing running shoe designed for serious runners focusing on high performance during long-haul endurance events and marathons. The shoe features a black and white color scheme. 

Technology and Performance

The 

Feidian 5 Challenger

 is equipped with several advanced features to enhance speed, comfort, and stability. 

· Midsole Cushioning: It uses full-length BOOM technology (supercritical fluid foaming technology) in the midsole, which provides high rebound and energy return while remaining extremely lightweight (under 200g for a US8.5).

· Propulsion (Carbon Plate): A T700-grade, spoon-shaped carbon plate is embedded in the midsole to boost forward propulsion and reduce peak foot pressure, enhancing running efficiency.

· Outsole Grip: The outsole is made with GCR (Ground Control Rubber) for superior anti-slip performance and wear resistance on various surfaces, including wet ones.

· Upper Construction: The upper is constructed with breathable BOOM FIBER material, which provides a secure, shadow-like fit with 35% better airflow compared to traditional mono materials, ensuring comfort during long runs. 

Intended Use

This shoe is built for competitive use and rigorous training:

· Occasion: Race day and marathon events.

· Users: Adult runners, particularly those focused on endurance and long-haul performance.

· Support: It offers stability support, helping to disperse pressure at ground contact.
