Wear whatever feels good to run in. Your body will tell you. The right shoes will feel magical like the right bike. (because they will be working WITH you, just like the right bike works WITH you)
Try a pair of Chaco Z1 or Z2 in the midst of your test-driving... just to humor me. They are great for midfoot striking. (the heel is neutral, even though the medial and lateral heel counters make it look thicker. I measured with a caliper, and my caliper don't lie)
