New with tags Bombas Slipper Grippers. They were too big for me as sizing is very specific to Bombas - see chart posted. Large size slipper will fit women’s shoe size 12-14 or men size 10-12.5 I did try them on (with socks) but not worn more than a few mins. From site: Half slipper. Half sock. 100% comfortable. We made these Gripper Slippers with a new and improved fit that’s still super cozy. They also have a soft brushed lining on the inside to keep you toasty, and special grips on the outside to help prevent slipping. Plus, every pair comes with a little travel bag that makes packing a breeze. While our grippers are pretty good at helping to prevent slips, they’re not magic. So be careful, and practice good coordination out there.
