I have plantar fasciitis and my New Balance shoes added a pulled achilies tendon to the mix.  I also weigh too much to be putting a bunch of stress on my knees.  I bought these to use for Zumba and my feet don't bother me as long as I am wearing them.  My knees are doing fine.  Even my ankles seem to like these shoes.  I'll buy them again.  They fit true to size (10) for me.  There is plenty of room in the toe area and the shank is very stiff giving really good support.  I will buy them again.
