Is it allowed to buy shoes made of pig leather?

Praise be to Allah, the Lord of the Worlds; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
The most preponderant view of the Muslim scholars is that the pig's leather does not become pure even after being tanned as tanning only removes the impurities that are not from the origin of the thing. In the case of pork it is impure alive or dead. So tanning can not purify any part of it as it can never be made pure. Consequently, it is forbidden to wear made shoes made from pork leather because they are impure and it is forbidden to wear impure things, as it is also forbidden to sell them.
Allah knows best.
