Same experience here.  After an entire summer wearing Birkenstocks, had to go 
back to sandals with orthodics as my plantar fasciatis flared up.

Paula,
I wore Birkenstocks for years because they were the best thing for me for the 
least amount of pain.  However the orthotics are deeper in the heel cup and 
that keeps your fascia from spreading sideways and allowing your weight to 
press down on the spur.  They are ten times better than Birks.  About $200
