Better protection of the strong material midsole is not directly affected by external factors and damage.

 The preferred embodiment of the active insole in the present invention is as follows:

 The fabric comprises cloth or leather; or the fabric is composed of a soft layer of cloth or leather, the soft layer is adhered to the base of the strong material; the soft layer is arranged to add corresponding softness, The thickness is determined according to actual needs; the substrate may use a cloth or a thermoplastic material according to the selection of different fabrics, and the thermoplastic material may include a vinyl acetate copolymer which is molded and shaped after heating.

(EVA) cotton, polyvinyl chloride (PVC) cotton or polyethylene (PE) cotton; the strong material midsole comprises a latex sponge, a rubber sponge or a polyurethane (PU) sponge which is difficult to mold after heating and is not easily deformed. material. The soft layer is any material that can conform to the characteristics that do not affect the structure.

 Compared with the prior art, the invention has the beneficial effects that large-scale mass production of the movable insole can be realized, and the production efficiency is improved; the movable insole made by the manufacturing method of the invention is not easily deformed, and It has better softness and brings comfort to consumers; especially the design structure which is not exposed by the strong material midsole can effectively ensure that the strong material midsole is directly exposed to external factors. Its structure is simple and practical. DRAWINGS
