Flame 4

Flame 4 focuses on breakthrough adaptability, enhancing running efficiency through innovative functional structures to deliver a revolutionary experience for runners of all levels. Internally, it features a self-developed spoon-shaped carbon plate that utilizes the dome effect. The forefoot part is designed as an inverse dome so that the foam can be thoroughly compressed when landing, thus creating a propulsive force. The heel part is designed as a dome to effectively disperse the ground-impact pressure and protect runners' ankles and knees. Additionally, based on the principles of sports mechanics, the carbon plate's middle section is designed to be harder and edges to be softer. This ensures smooth power transfer, providing forward momentum while offering flexibility and stability during turns. Scientific laboratory tests have confirmed that this groundbreaking carbon plate design reduces ground contact time by approximately 2.7%, significantly improving their performance.

In terms of design, the heel's forward-curved shape and optimized sole rolling arc enhance the rolling sensation during ground contact and the forward-rolling efficiency. Meanwhile, the forefoot's curved-surface arc boosts lateral-rolling efficiency. Besides, the asymmetric cross-section design offers comprehensive structural support throughout the running, landing and starting process, thus preventing sports injuries. The overall design reduces the barrier to entry for running, allowing runners at all levels to enjoy a professional-grade experience.

With its exceptional improvement in running efficiency and universal adaptability, Flame 4 allows every runner to experience the joy and passion of running, inspiring more people to join the running movement and elevate the nation's physical fitness.
