In this embodiment, the inertial impact caused by the movement of the center of gravity is mainly borne by the outer side of the sole 6 by the transformation between the single support phase and the double support phase during walking, and therefore the center of the partial guide rod 2 is biased to the outer side of the support beam 1 for guiding gait to the inner side.

In the above embodiment, referring to fig. 1, the above device has a plurality of guide bars 2, adjacent guide bars 2 are spaced apart by a distance, and the distance between the outer ends 21 of the adjacent guide bars is greater than the distance between the inner ends 22, i.e., the plurality of guide bars 2 are distributed in a radial form on the support beam 1. The guide rods 2 and the support beam 1 form a whole, when part of the guide rods 2 are bent and deformed, the guide rods 2 conduct bending stress to the support beam 1, the support beam 1 generates certain torsional strain, the support beam 1 conducts torsional moment to other guide rods 2, the whole device generates moment opposite to the direction, and when the double support phase and the single support phase are converted, the whole half sole guides the gravity center of a human body to approach to the central line.

In the above embodiment, referring to fig. 1, the shoe further comprises a frame 3 adapted to be fixed to the shoe side, the frame 3 is fixed to the support beam 1 by a support rod 4, the support beam 1 is disposed along the center line of the frame 3, and the support rod 4 is adapted to be inserted into the arch position of the sole 6. The support beam 1 and the guide rod 2 guide the gait of the forefoot portion to transmit the moment returned to the center line to the whole sole 6 through the frame 3, and the sole 6 integrally generates the moment to the inner side so as to eliminate the tendency of the sole 6 to turn outwards during walking. While the support bar 4 may function to support the arch.

In the above embodiment, the frame 3 has a plurality of inward protrusions 31, so that the device is more tightly combined with the sole 6 when the device is integrally formed with the sole 6 by injection molding or the like, and the protrusions 31 can prevent the shoe side from returning to the center line due to excessive deformation after the shoe side is subjected to the force conducted by the frame 3.
