seems my flat slippers were hurting my ankles.  So I bought my mules at Easy Spirit - what a difference!  They are wonderful!  My ankles no longer hurt -have been wearing them for over 3 years now -and when one pair wore out I bought two more!  they are comfortable- Just ordered my 4th pair - have a pair at my daughter's home and of course, a pair here at our home- I do not wear them outside the house, tho sometimes I forget I am wearing them when I walk outside - and walk back in home to put on my gym shoes.
