I bought these for a wedding. I absolutely needed 15cm heels due to my height and the dress, but these were incredibly easy to walk in because of the platform and the thick heel, and I didn't get tired even while wearing them throughout the ceremony. You can't see the shoes at all when wearing the dress, but I was very satisfied with these shoes. The ankle strap is a little troublesome, but it provides a lot of stability. Used only on the wedding day. There is some wear and tear. (On the front of the right shoe and the heel. None of it is very noticeable.) Shoe size: 23.5cm Heel height: 15cm My usual shoe size is 23-23.5cm, and the size was just right when wearing stockings. Those who are planning to use these for a wedding may have some concerns, so please feel free to ask any questions.
