Not just a ball cushion, and not quite a full gel shoe insert, Pretty Kitty Extended Ball of Foot Cushions provide comfort from heel to, well, almost toe. Extended gel padding increases stability by decreasing sliding inside shoes of all sizes, types and heel heights. Self-adhesive backings stay put - simply lift and pull to adjust or change them to a different shoe. While thinking about comfort, we didn't forget about cuteness - the light blue breathable fabric is covered in a cute kitten pattern.
