Please only purchase if you have the knowledge to do so, to prevent any issues. This is an EVA half insole for size adjustment, included with Caravan shoes. It was included with a 28cm shoe. Please check the photos for the model, etc. I am unsure which shoes it is compatible with. Please be sure to check the second photo. It is new and unused, but it was in this condition from the beginning. If you are at all concerned, please refrain from purchasing. - Material: EVA - Purpose: Half insole for size adjustment Instant purchase is welcome.
