This is because the animals usually die naturally and then their skin is taken off so they are not hurt. Also the only other shoes you can wear are plastic which are bad quality and look awkward. Or you could wear vegan shoes which are very expensive as they are harder to produce. On the rare occasion cows will be bought up to be killed for leather. Some people will say this is not right, but at the end of the day they are probably wearing products made from leather as they are pretty much in every shoe shop.???? Kids that go to school will also wear leather shoes as part of their uniform. They also look smart so they are good for buisnesss meetings and interviews.
