I purchased these on Mercari in February, but I ended up buying four pairs of the same color and won't be using two of them, so I'm listing them. Below is the product description from when I listed them: Brand new, unused, authentic, purchased in January from the official website. Unisex. 【Product】Pitsole 【Size S】 (23.0～24.5cm) 【How to Use】 1. Remove the original insole. 2. Place the Pitsole on top of the original insole, aligning the heels. 3. Trace the excess toe area with a pen, etc., and mark it. 4. Cut off the excess with scissors, etc. 5. Place it in your shoes and check the fit. Size...23.5cm
