I have posted insoles for folks whose main issue was forefoot rather than hindfoot.

If your dorsiflexion is limited, that can cause whip callousses regardless of hindfoot varus or valgus. Tight ITB tends to hang out with tight calves.

The iliotibial hoopla could be caused by the pelvis or by the foot. (which came first, the chicken or the egg?) I'm doing a little literature search project RIGHT NOW on foot posture and its effects on pelvic dysfunction. Hit up http://scholar.google.com and search "pelvis" and "overpronation". Pretty cool stuff.

I'm thinking you've got all the foot goodies (superfeet, shoes, etc) just fine, and you know what you need to stretch, now you need some posting. But my bias is always toward feet.

(BTW, I worked with an ATC once who *swore* that tight ITB were caused by overpronation, and treated ITB stuff almost entirely with medial wedges.)
