The answer to the question "Why you shouldn't buy shoes with leatherette lining" I will give on the example of pictures.
Even if we overlook the fact that the use of any synthetic materials in shoes, ranging from creams, waxes, impregnations and artificial leathers, do not allow the skin of the feet to breathe normally and exclude the ventilation of the feet, artificial leather cannot withstand the load in shoes.
In this picture you can see that the faux leather lining started to burst after (attention!) EIGHT uses of the boot!
Not only the back of the lining began to burst, but also the insole.
Moreover, the sole itself is made very well.
The shoes are made in India. You can imagine how much they would zip through if they were made in China.
