Ever since discovering Orthaheel products a few years back when I had plantar fasciitis, I can find no better foot relief.  These sandals replaced another variation of the same slip ons - and are just as great.  My PF is no longer a problem, but these shoes massage your feet and put them to rights after wearing other styles of shoes; excellent heel and instep support.  Too bad they aren't dressy enough for formal wear!  HaHa.  (Just don't order them directly from FOOT SMART - they NEVER get the order right!! Thank heavens for AMAZON!!)
