The inner lining cushion for the shoe feels great but wearing these all day does wear down the cushion insert and I wish I had more inserts to replace since after only 2 days the insert began to peel off & shred.  The elastic band that runs over the top of the shoe makes an impression on the top of the foot (which is visble when you remove the shoe after wearing it for a couple of hours)--some wearers might find this bothersome & may experience issues with circulation if the band is too constricting.
