• The insole of these men's sandals is ergonomically designed to fit the shape of the foot, reducing the strain of walking. The top of the insole features a geometric texture, which provides good slip resistance. • The sole of the men's flip-flops is made of highly elastic EVA rubber. Its double-layer design enhances softness and comfort. The surface texture of the insole is decorative and non-slip, beautiful and practical, and dries quickly. • Outer material: Leather (the outer material of the herringbone strap is made of specially treated leather, and the textured decoration makes the men's flip-flops not only beautiful and stylish but also shinier), Inner material: Textile (the soft strap lining does not rub against the toes, and the equally soft toe design will ensure your comfort while walking, allowing for long-term use without hurting your feet)
