The first kind of big foam, there will be a flat punching trace on the edge, which means that the edge is flat and straight, so there are limitations in the sole style.

The second kind of small foam, that is to say, is made by pouring EVA processing materials into the opened small foam mold, then expanding a certain size of the mold through high-temperature foaming, and then putting the small foam mold into the secondary mold for heating and cooling. This method is very stable, but the output value is low. This kind of sole is usually made of high grade, and the appearance stripes will be excellent.

Third, the EVA processing material is poured into the feed barrel to be stirred into a liquid state through high temperature, injected into the mold, and then cooled and shaped. In this way, the length of shoes is not stable, which is often used in foreign orders for some waste shoes. Of course, the offer is relatively cheap.
