I purchased several pair of red slippers for my elderly mother (90 YO) who has been wearing the allspice color for some time now. The sole on the red slipper has a fabric embedded in the rubber which is different from the allspice slipper sole. The sole fabric offers little traction on our tile floors and is proving to be a hazard, especially for an elderly person. I plan to exchange the red slippers for the allspice color to avoid any falls.
