Michael Kors Slip-ons The shoe size is written as 6.5M, so I believe it is 23.5 cm. (See the last photo) As you can see in the 5th photo, there is some fraying. I purchased these 2.5 years ago, used them a few times, and then stored them. There is a black stain in the 4th photo. Please understand that these are used items before purchasing. There are scuffs and stains, so please refrain from purchasing if you are concerned about them. I have pets, so there may be some pet hair attached. Please refrain from purchasing if you are concerned about this. Please refrain from purchasing if you are sensitive or looking for new items. They will be folded for shipping, so please be aware of this. Please make your decision after reviewing the images. There may be some overlooked details, so please understand.
