The product adopts a straight C-shaped foot surface, a double-layer carbon plate design, and a bow-shaped heel shrapnel, which greatly stores the energy during the support period, and releases the rear pedal force in the later stage of the exercise through the rebound of the top carbon plate. Living contact surfaces provide multi-axis stability. The pneumatic cylinder is designed with two weight levels according to human mechanics, each level can cope with the third to fourth level of exercise intensity, suitable for people who have medium and high intensity exercise. The pneumatic ankle joint improves the coordination, mobility and stability of the foot. Especially on rough roads, the air pressure ankle rebalances and adjusts the force point of the foot according to the feedback information from the forefoot and heel of the foot, so that the force on the foot is more uniform, and can better adapt to complex road conditions, such as slopes, steps, hills, etc.
