Gripper Slipper Now made with a thicker footbed for extra cushioning, these Gripper Slippers have an ultra-warm brushed lining and special grips on the outside designed to help prevent slips. You may never want to wear real shoes again. While our grippers are pretty good at helping prevent slips, they’re not magic. So be careful, and practice good coordination out there.
