Never worn, still in packaging. These are sold out on the Bombas website. Bombas accidentally sent me two extra pairs. "Now made with a thicker footbed for extra cushioning, these Gripper Slippers have an ultra-warm brushed lining, special grips on the outside designed to help prevent slips, plus a separate travel bag that makes packing a breeze. 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."
