Veg-tanning is the most common leather. Its name comes from the bark of plants and trees in the process of tanning. These plants combine to create hard but natural colored leather. The light color of vegetable tanning will not be retained for a long time, and will become soft and deep with time, showing a unique luster. It should be noted that Veg-tanning cannot be soaked in water, otherwise it will shrink and become brittle after drying.

Roughout is the leather used to make the uppers from the roughest part of the inner layer of animal skin. The leather has a soft surface, granular texture structure, and is very thick and durable. Roughout is the favorite material for boots worn by Marines during World War II, because smooth uppers are not required for combat, and Roughout has better breathability than other rough leather.
