I've been using this manufacturer's series and love it because my feet don't get tired, but I'm selling these because they felt a little small after wearing them about 5 times. They're genuine leather, light, and easy to walk in. They are a size M, which is 23cm. *However!* The inside is peeling a little. The price was a bit high, so I thought it was too soon to get rid of them. The outer leather is still in good condition, so if the size fits you, please consider them.
