These boots have only been tried on. The heel height is 10 cm. They can be worn as over-the-knee boots if the folded-over part is raised, or as long boots if it's lowered, allowing you to adjust them to your fashion. As shown in photos 7 and 8, there are stains on the inside of both boots. Please understand that these have been stored at home. Since shipping is included, I will not offer a discount.
