The application of carbon fiber in running shoes can be attributed to several of its advantageous properties.
Research indicates that 85% of sprinters using shoes with a higher degree of longitudinal bending stiffness within a specific range have noticed some level of enhanced athletic performance. An increase in this stiffness can particularly benefit the initial 10-meter acceleration phase of sprinting and can effectively lower oxygen consumption during jumping and directional changes.
Furthermore, adjusting the longitudinal bending stiffness of running shoes can influence running biomechanical parameters, consequently affecting running performance and economy. The enhanced stiffness can shift the ground reaction force during the running support phase forward, thereby extending the force arm of the posterior calf muscle group and increasing the strength of the ankle joint push-off phase, giving the foot a propulsion boost.
Carbon fiber also provides anti-torsion and strong support. Studies show that abnormal arch structures can heighten the risk of sports injuries. Carbon plates can reinforce the midsole of sports shoes, improving structural rigidity, ensuring arch stability, and offering anti-torsion protection. A good anti-torsion design can also enhance the cushioning system’s performance, ensuring a comfortable foot experience and making running shoes more stable.
Additionally, carbon fiber running shoes can offer a certain rebound effect. The carbon plate and the midsole of the running shoe work together to form a “sandwich” structure, which can better utilize the runner’s power, improve the rebound propulsion ability, and reduce energy loss.
In summary, carbon fiber has established a close collaboration with sports shoes due to its excellent performance.
