> I have a bit of a flat foot but otherwise no pain at all. Should i keep wearing them for health's sake? Will my feet eventually adapt to them and stop hurting?

Also experienced this (also flat footed) but the pain passed after a couple of days - stick it out.

The great thing about Birkenstocks are the versatility. Good for walking long distances in the city; light hiking in the countryside or getting your feet wet at the beach.
