The terms "real leather," "genuine leather," and "pure leather" are often used to describe different qualities of leather in shoes. However, it's important to note that these terms can be somewhat misleading, and the quality of the leather can vary.

1. Genuine Leather:
- "Genuine leather" is a term that is commonly used to describe real leather. However, it's the lowest quality of real leather.
- It is made from the layers of hide that remain after the top-grain has been separated.
- While genuine leather is real leather, it may not be as durable or high-quality as other types.
