Snuggle up in these super-soft, lightweight pull-on slippers. Fluffy faux lambswool is warm. And the soft construction is thin enough to pack away in your luggage (or desk drawer at the office!) My feet at about size 7 but very wide, so these were just a teensy bit to snug for me. I’m considering them size “small.” Estimated best fit: Ladies 5.5-wide to 7.5-medium width. Once only once! Almost Perfect condition.
