“Vegetable-tanned” means just that. Tanned using vegetable matter, tree bark tannins. This is the ancient way of tanning leather. We went for pure and clean, a product of nature. This means that a pair of Pierre Giorgio shoes will decompose afterabout 100 years without leaking chemicals into the environment.
We love vegetable tan because it is the purest expression of what leather is. The veggie tan develops a rich patina which means the more you wear your shoes the more custom to you they get! If you leave them in strong sunlight or get skin oils on them the color will deepen and darken. Our leather is tanned from organic material like tree bark tennis and finished with a basic wax. Vegetable tanning is the most natural state possible.
