◪ With excellent forming property and machinability, it is easy to skive and mould into insole shape. |
◪ High bonding strength between layers, no leafing will happen due to punching and cutting process. |
◪ High hardness and density, offer enough support force for insole and in case of heel dropped. |
◪ Nicely bonding with insole board and wont separate after warping |
For shoes industry: Shank board as the most important part of shoes insole offer supporting force of entire shoe. It can be used for making leather shoes insole, high-heel shoes insole, gym shoes insole and leisure shoes insole.
