What is the material of pressure shoes

Pressure process, also known as injection process. The bottom making process is roughly similar to the molding process. It is characterized by high production efficiency and low cost, and the plastic can resist oil and insulation. The pressure injection process is applicable to the production of shoes for civil use, tourism, labor protection and so on. Pressure shoes are relatively stronger. As soon as the adhesive shoes meet with water or other solutions, it will cause glue opening. But pressing shoes is to press the upper and sole together through strong pressure. The pressure of normal movement cannot exceed this pressure, so it is not easy to open.
