Crafted from medium-weight calf suede, the leather is overdyed with a Japanese pigment derived from carbon powder. The skins undergo a washing process to achieve an uneven finish, while drumming with wax provides a natural, waxy texture. Due to the natural pigment, variations in shade are expected and will evolve with exposure to light and humidity. under-ankle height 8 eyelets with laces toe caps shark-toothed bumper soles triangular leather applique on the side padded ankle contrast stitching calf leather upper cow leather lateral details calf leather lining calf leather insole thermoplastic rubber sole
