These slippers have  a removable insole, which makes them perfectly suitable for your own arch support or other insole. The slipper has a nice finish with a narrow brown leather label on the side of the instep and on the heel. This means you can easily slip into the slipper and it will not slip out either. It just gives a slightly more pleasant wearing comfort. The inner lining of this slipper is made of breathable material with perforated holes so that you do not sweat while wearing it.
