Denton and Ed,
Thanks again for posting. Denton, as for the high heel, I've never been able to deal with them. They cause me to hit heel first, and I've always been a midfoot to forefoot striker. My stride is more of a loping one than a high cadence one, I guess, but since I'm 6 ft. 2 in., that seems normal to me.
Ed, maybe you're lucky. My problem is that, without a big toe lift, all the pressure and first contact point is at the base of the second toe (aside from being inefficient, there are big calluses there too.) Such is life (running, that is).
