As I’ve always understood gait it is the amount of inward roll from heel to toe off. I’ve been told that I mildly overpronate (like many others), but have been using more of a midfoot landing the past couple years. The problem is, as I’ve viewed in slo-mo that I land on the outside of my foot (near the middle of my foot length-wise) and drop to the ball of my foot. Should I be landing more flat on the mid foot? I’ve been having minor ITB soreness, but of course can’t be narrowed down to any one particular thing. Without heelstriking and rolling to toe off, how do know if I’m still considered an overpronater. To those in the know I’m sure this sounds pretty stupid, but I’m being serious, so take it easy on me here.
It is normal to land on the outside of the foot (lets just call it “supinated” to keep things easy), then pronate during stance phase (to adapt to uneven terrain, unlock the forefoot on the rearfoot, absorb shock, etc.), then resupinate at the midtarsal joint just before toe off as your foot now becomes a rigid lever via the Windlass mechanism/plantar fascia. This all happens pretty quickly!
So, pronation/supination are normal and necessary movements. Too much or little can cause a myriad of issues. It is common for “overpronators” (I’ll just have to assume) to have ITB issues. But, more specifically, it is the RATE of pronation that tends to cause ITB issues than the actual AMOUNT of pronation. I’ll leave it there for now, as my verbage goes quickly downhill from here … 
In short, you don’t have to “heel strike” to pronate/supinate. These words decribe a tri-planar motion. Some of use have more motion in one plane than others (ie the foot abducts or is duck footed, or another is too plantarflexed from tight calves).

Good stuff Rod. Don’t hold back on our account…
Thanks for the response. I’m learning little by little. Is there a way to slow the rate of pronation (technique, shoes?). Will a more supportive shoe control the amount of pronation for the mid foot strike as well as it does for the heel striker?
Sure - most of which is already good anecdotal things many slowtwitchers already do. higher cadence (180 foot strikes/min) with feet centered under your body for one. Shoes with a medial “post” (basically a different density foam/EVA on the medial site just forward of the heel usually). Good, snug heel fit. solid surfaces are better than sand, etc.
