【Please see my profile】 LUCIANO VALENTINO Office Sandals with Straps Size M Black Since only the size M is indicated, I have listed it as 23 cm. I usually wear 24 cm. They have been washed with water, but there are some pills on the inside, so they show signs of use. Please note that the rubber part of the strap on the right foot is twisted. The material is likely synthetic leather. It's a soft material, so it's unlikely to hurt your feet. Due to the high shipping cost, price reduction is not possible.
