One pair of insoles 100% bovine leather, chosen for its hard-wearing qualities. Vegetal tanning.
- The natural manufacturing process for these insoles has not changed since the Egyptians developed it. Dating back to ancient Egypt, this vegetal tanning technique transforms a raw skin into a supple, strong and rot-proof material called "leather" by soaking the skins in containers with tannins extracted from oak, birch, willow, mimosa...bark or exotic wood bark which adds resistance against parasites.
- Next to better parasites resistance, this tanning process confers a more alive aspect to leather as well as its pleasant leather smell, helps it acquire an elegant patina during its long life and offers a comfort synonym with hygiene.
