The Martha boots are classic mid-calf boots. They have a sleek upper made of soft natural leather or suede - thanks to noble materials, they age beautifully and maintain their shape for years. They are minimalist and without decorations, fitting all everyday styles and elegant outings. They pair well with denim, smart trousers, and tights. They have a small comfortable heel. It's a good match!Upper: genuine natural cow leatherLining: genuine natural cow leatherInsole: genuine natural cow leatherOutsole: synthetic material
