The FuelCell LD-X are designed for running distances from 3K-10K.
The upper is made of light mesh, which ensures optimal breathability when conquering more meters. The FuelCell foam insole ensures maximum support, lightness and also the highest level of cushioning while running. The shoe is equipped with a carbon plate that is located along the entire length of the sole. The properties of carbon fiber significantly affect the dynamics and speed achieved during running. They are based on the strength and flexibility of the plate made of this material. During the impact, the fiber bends slightly to subsequently, in the rebound phase, release the energy stored in it.
