The material is fabric, not synthetic leather. Size 38 Heel height: 7cm Length from opening to sole: approximately 13cm Because it's fabric, these boots can be worn for a long time throughout the year. I've worn them many times over the past 5 years. I will have them cleaned to remove any odors before sending them. The toes are slightly peeling, but it's underneath the toe, so it's not noticeable when worn. The sleek, slim design makes your legs look beautiful.
