I kept this at my parents' house. There's no brand logo, so it seems to have been custom-made. I don't know the material either. The soles are clean, so I think it's mostly unused, but I don't know the details, so please judge from the photos. Sole thickness: 3.8 cm Boot length: 41.3 cm (measured from the ground) Boot outer circumference: 34.3 cm (measured around the calf from the top of the boot)
