【High-Quality Pig Nume Leather】The surface of the insole uses high-quality pig leather with excellent abrasion resistance, extending the life of the insole. The surface has a luxurious black and brown color scheme, so you won't be embarrassed even when you take off your shoes. These insoles are specifically designed for leather shoes. 【Comfortable Fit】Pig leather has natural deodorizing, sweat-absorbing, and breathable properties. The punching design on the insole surface enhances breathability. Thanks to its natural sweat-absorbing and deodorizing properties, you won't feel uncomfortable even if your feet sweat, as it absorbs sweat from your feet over time and also acts as a deodorizer. 【Ultra-Thin & Shock Absorption】The bottom of the insole is made of integrated PU material, so the entire insole provides shock absorption performance. The insole is only 4mm thick, so it won't feel cramped inside your leather shoes. 【Usage Scenarios】Suitable for all kinds of leather shoes, such as commuting, work, travel, and long walks.
