The Shoe Industry is fundamentally flawed. The design of shoes today is to cushion people’s' foot strike. The vast majority of folks out there have goofy (incorrect) strikes which are the result of poor posture and a shitty stride. As such you see the Shoe Industry pushing big heel to toe drop ratios, a mega shit ton of padding under the heel, and narrow toe boxes. Shoe construction that purports to provide support / correct pronation or supination only add to the problem.
I have suffered through all of the common injuries - TFL / plantar fascitis / back and hip / shin splints - many of these requiring months off of running.
99% of all of that can be corrected by concentrating on perfect posture - forcing you pelvis under / forward, and engaging your glutes with each stride, leaning forward from the ankles up, use the upper body and head to adjust CG based on slope, and “stand tall”. Stride - pull the heel toward your ass, a high knee, a gentle landing on the ball of the foot, a brief touch down on the heel, and the foot always lands under the center of gravity.
When I look at my old Brooks I see lots of wear both under the ball of the foot but also on the outside of heel (and I remember on long runs how the padding under the ball of the foot felt insufficient - which probably contributed to the heel strike). Since really focusing on posture and stride and switching to Newtons - I see even wear on rubber pads under the ball of the foot (hey, where the padding ought to be, right?) and I see the slightest wear in the dead center of the heel. (I have @ 200 miles on this pair of Newtons by the way) I am back to running low 20 miles a week, and hope to be back to more like 30 by the fall.
Seriously - posture and stride (and rational training schedule) = injury free.
Shoe industry rant off.
