ZARA Side-gore boots Chelsea boots Size: US39 - Color: Beige - Design: Chelsea boots - Heel height: 8cm Sole thickness: 3.5cm - Material: Synthetic leather Thank you for viewing. I purchased these online and only tried them on at home. However, they are still considered used, so please consider carefully if you are concerned. I usually wear 24.5cm shoes. Since my feet are wide, US39 fit perfectly with regular socks. I think they would also fit someone with narrow 25cm feet. They have a heel and are a bit long, so I think they will make you look taller.
