teigyr- Yeah, at work I see a lot of runner's feet, and a lot of them have the same calluses- especially women. Another big clue is if your big toe is "drifting" away from midline and towards your other toes. Look on the bright side- at least your feet show that you're active!

Thanks Wahine and Knotted- although I KNOW I need to increase the flexibility in my hips- it's a bit of an uphill struggle. Ah, well, I'll try a one-woman experiment to see how much improvement I get. You would think, since I spend all my free time volunteering at PT clinics, that I would get the hint. And Knotted- maybe someday I'll track you down to talk geek about insoles.
