mercibeaucouq, these are platform sandals! One part of the upper that touches the top of the foot is see-through, allowing the skin to show! The heel part has Velcro, so you can adjust it to fit your ankle! They have been used a few times, so please check the condition of the soles. The size is 02, which I think is about 24.5-25cm. Platform height: toe 3.5cm - heel 6.5cm Weight: 369g per shoe Color: Black
