DIP is DIRECT-IN-JECTION PROCESS. In the process, the elastic damping material will be directly injected into the shoe model, it is not necessary to use any glue or stitching. Through this technology, soles and uppers can be closely linked.
Because there is no thick layer of glue between the uppers and soles of the shoes, the characteristics of the DIP technology is light and breathable.
But how to identify whether the shoes using this technology or not?
It is very easy. A lot of shoes have clear sutures and glue marks. Instead of using the DIP technology in the soles of shoes, it is only a faint line of bonding.
