I think that this company want to make sale only.They were not thinking about that material is more good for customers or not.
They were only want that we should get more sale but thet were not using no 1 materials.sometime they were getting hug lot for shoes making.
In this sometime it is deffect materials they were used bez sometime they were mixing other materials also bez they were want to make shine in shoes.They were not making soft shoes that customers must like it.In this company the shoes not making for health purpose that we should be required bez daily life many person have problem in feet that they were want soft and health shoes.I can say plz make health shoes for customers for feet problem.
