The Shoeboy's Natural Leather Insole is made of 100% untreated leather resting on natural cork. This combination of high-quality materials offers you a pure natural product with numerous benefits. The insole leather is vegetable-tanned, providing high breathability. This allows for good air circulation in the shoe, helping to reduce the formation of unpleasant odors. At the same time, the leather retains moisture in the shoe, preventing foot burning. A special feature of the Shoeboy's Natural Leather Insole is its thinness. It adds minimal bulk and conforms perfectly to the shape of your foot. This ensures excellent comfort without making the shoe tighter or losing flexibility. Additionally, the insole provides extra protection for the shoe's insole. By placing the insole between the foot and the shoe, the insole is spared from wear and tear, extending the shoe's lifespan. The Shoeboy's Natural Leather Insole is a high-quality product that enhances your shoes and provides your feet with a pleasant wearing experience. Discover the natural comfort and protection for your feet with this unique insole.
