Suede: leather cut from the back, while the fibers remain on the surface, suede is less prone to damage than nubuck.

Cork: is a popular, purely natural, and easily renewable material that stands out for its properties such as flexibility, strength, durability, and water resistance.

EVA: most commonly used as a midsole material, because it has very good shock-absorbing effect, it also excels among other materials in its crack resistance and elegant smooth surface.
