lol - tell us all about your feet!

Let me ask you something. Can you say, put on a pair of running shoes (sans orthotics) and run a 5k w/o pain? More broadly, are you able to exercise w/o pain w/o orthotics?

I have rather flat feet - I leave a nice, full footprint on the beach :P

If I don't wear them, my feet roll excessively inward because of the virtual non-arch, which then throws my entire lower body out of alignment. Hello knee-hip-back pain
