Top selling item with rave reviews and you're discontinuing these?  Why?  These are the only shoes I can walk in comfortably.  I wear them to work, for evenings out, for gardening...everywhere.  I can walk in them for hours and my feet don't sweat or hurt.  They help with the heel pain and provide a wonderful cushioning for my lower back and knee pain.  I have 4 pairs and would gladly buy 20 more if I could.
