Total length: Approximately 24cm Heel height: Approximately 5cm *Measurements are approximate. Please allow for minor discrepancies. Please refrain from purchasing if you are overly concerned about details. If they feel tight, adjust the thong by pulling on it. Due to aging, there is some stickiness on the underside of the thong. In my amateur opinion, it should not affect use. Thank you for your understanding. I believe they can still be used, but they are used items, so please check the current condition in the photos and consider purchasing if you are satisfied (⁎ᴗ͈ˬᴗ͈⁎)
