The sole is made of sturdy rubber. I wore them once in the entryway, but haven't worn them outside. The leather is also very soft and easy to wear. The sole height is 5 cm, but because it's connected, you don't feel the height at all. These shoes allow you to enjoy different looks depending on the color of your tights or socks.
