PU leather is water resistant
Perforation just means punching holes through the leather or PU. So, just the term perforated leather cannot determine whether it's genuine.
PU leather and vegan leather are similar but not exactly the same. PU leather, made from polyurethane, is a type of synthetic leather that mimics real leather while being more affordable and easier to maintain. Vegan leather, on the other hand, refers to any non-animal-based leather alternative, which can include materials like cork, rubber, or other synthetics, including PU. Therefore, while all PU leather can be considered vegan leather, not all vegan leather is PU leather.
Yes
genuine leather is better. polyurethane leather (or PU) is not real leather.
No
No, it doesn't. PU leather doesn't act much like leather at all. It does not go more supple over time, and it does not change color or develop a patina(ex: the vachetta on real Louis Vuittons develops this patina, a PU leather counterfeit would not)
PU Leather is when a Polyurethane sheet is applied to a thin leather back when used in the furniture industry. A leather pattern can be stamped on the PU to make it look and feel like top grain leather. PVC - Polyvinyl Chloride is also manufactured in a similar manner but is normally placed on a cotton or polyester backing. Pattern can also be applied to the surface. PVC can be a more durable surface than PU, but does not feel like leather. Also referred to as Vinyl covering for Furniture use.
Some leather is waterproof if heavily polished.
No. It means what it says - that the upper is made of leather and is waterproof. It says nothing about the sole and it says nothing about the stitching.
PU leather is an animal-based leather product that is made of thin sheets of split hide that is laminated on top of a substrate (sort of like a veneer on wood). Technically, what you were told is true, as PU leather is not the full hide, just a thin layer of leather. But it is animal-based.
The scientific name for artificial leather is polyurethane (PU) or polyvinyl chloride (PVC) leather.
Leather is porous, so even though it might be better at repelling water than other leathers, it is not completely waterproof.
