Bombas Women's Sherpa-Lined Gripper Slipper Bootie. Size: S (7-8.5). Only worn a few times. Smoke-free, cat-friendly home. "Everything you want in a grippy house slipper and more. More cushioning, thanks to an extra thick footbed that makes every step pillowy soft. More warm coverage, thanks to a fluffy sherpa lining that extends above your ankle. And more cozy style, thanks to the chunky yarns and oversized ribbed cuff, which look festive, textured, and cute to boot. While our grippers are pretty good at helping prevent slips, they’re not magic. So be careful, and practice good coordination out there."
