Can moldy soles be greatly reduced?

The sole mold can be changed from large to small. At present, some sole molds on the market can't adjust the size of shoes well when they are used, and it is not convenient to measure the size of shoes at any time when they are used, which is not conducive to users' observation. Moreover, they can't perform double-layer processing well, which is inconvenient to use and can't meet the needs in practical work. Therefore, there is an urgent need to improve the technology of shoe sole mold with adjustable size in the market.
