Are Lacoste shoes actually made of alligator skin?
There are shoes made of crocodile skin, but the vast majority of
shoes that are made of animal skin are made from cowhide, and
nowadays most shoes are made of "man-made materials" like cloth or
plastic unless they explicitly say they're made of something else.
(And even then, you may need to understand the terminology; "patent
leather" is really a kind of plastic.)
