Words mean things. No one with any knowledge of real-world foot biomechanics would ever discuss midfoot striking. So why would anyone obsessing over meaningless distinctions between heel strike and forefoot strike adopt a non-sensical vocabulary to discuss it even further? To be taken seriously in an argument, one should become informed on the actual anatomy, biomechanics and semantics. Just an opinion from "almost a doctor". By the way, it doesn't matter anyway. Fast is fast, slow is slow, and whoever reaches the line first still wins, on his heels or not.
Midfoot= cuboid, 3 cuneiforms, bases of the metatarsals which never touch the ground barring severe deformity. Your "midfoot" is equal weightbearing on the calcaneus and the metatarsal heads.
