I'm having some issues lately, sometimes it's one foot, sometimes the other. Seems to be tendon or muscle pain at the "point" on my first metatarsal. Not bothered more by putting weight on it, but hurts to bend my toe back (whether on the ground or in the air). It seems to bug me after looong runs.

I'm guessing it's probably my shoes, but can't figure out what about them causes it? And also curious - I have a half marathon Sunday. Would you buy a new pair of shoes (a model that you know worked in the past) and wear for the race, knowing that you'll have pain if you don't?
