Suede with a shearling lining. The main body has no noticeable stains, but the soles are rubber and have black marks. Size is 7.5, which I believe is about 26cm in Japanese size. Please refrain from purchasing if you are sensitive to used items, as this is a used item stored at home. Thank you. Suede section: Heel to opening: 20cm Opening circumference: 36cm Heel to toe (outer sole): 30cm
