The size is marked as M (outer sole approximately 29.5cm, maximum width approximately 11cm), which I believe is about a 27cm. The material used is suede. The outer sole uses Vibram, making it a genuine construction, and it's surprisingly lighter and easier to wear than it looks. The condition has some spots like stains here and there, and there is wear on the heel soles. Please check the images. If you like it, please consider it. Thank you for viewing.
