[0006] Preferred technical solution 1: The elastic support mechanism includes an arc-shaped support frame fixedly connected to the middle part and the arch part of the foot, the arc-shaped support frame is an elastic frame, and an arc adjustment component is connected between the two ends of the arc-shaped support frame, and the arc adjustment component is used to adjust the arc of the arc-shaped support frame.

[0007] Preferred technical solution two: the arc adjustment assembly includes a threaded rod 1 hingedly connected to one end of the arc support frame, and a threaded rod 2 hingedly connected to the other end of the arc support frame, and an adjustment cylinder is sleeved between the threaded rod 1 and the threaded rod 2 and threadedly connected to the two.

[0008] Preferred technical solution three: a plurality of elastic support mechanisms are arranged in parallel on the bottom side of the arch of the foot, and the arc shapes of different areas of the top surface of the arch of the foot can be adaptively adjusted through the plurality of elastic support mechanisms.

[0009] Preferred technical solution four: The front and rear ends of the arc-shaped support frame are fixedly connected with elastic extension legs, and the elastic extension legs are in contact with the sole of the shoe, and the elastic extension legs can provide elastic support for the arch of the foot.

[0010] The above structure enables this solution to have the following beneficial effects:

[0011] 1. The support height of the arch portion can be adjusted by the arc-shaped support mechanism arranged on the bottom side of the arch portion of the insole, so that the height of the arch portion is consistent with the support height required by the arch of the wearer;

[0012] 2. The setting of the elastic extension legs at the bottom of the arc-shaped support frame ensures that the arch of the foot has sufficient elasticity to improve wearing comfort. BRIEF DESCRIPTION OF THE DRAWINGS
