These are truly very comfortable. I have achilles tendonitis and need to wear a cushiony higher heeled shoe. Was hoping these could be an alternative to sneakers for walking but they sort of slipped off my feet during a test walk. I need to have an open back shoe for walking as the swelling (from the tendonitis) gets irritated from the backs of sneakers.. But the aches I was getting from regular shoes no longer occur. I wear these all day long at home!! Will buy another pair.
