These slippers are very comfy with their secret sole.  I have fallen arches so they give my feet the support they need.  Also, the indoor/outdoor sole comes in mighty handy if you step outside to put the garbage in the dumpster as I do occasionally.  If the ground is wet you need not fear that your slippers will pick up any wetness at all.  Have not washed them yet, but I consider that an added bonus for sure.
