I started distance running in ~2007. Ran my first marathon in training in 2008. Ran the 2009 LA Marathon as my first “official”.
When I started, I had my gait analyzed by an “expert” at a reputable local running shoe store. They put me in “stability/motion control” shoes. And I kept running.
I soon developed chronic ITB issues, severe enough to shut down my running entirely. Nothing helped. Then the “barefoot” craze took hold (Born to Run and the likes). I figured I had nothing to lose. Ditching the “motion control” shoes and literally running barefoot (and adopting a mid/forefoot strike), I took my first pain-free runs in many, many months. The ITB issues went away quickly. I subsequently went the zero drop route and ran many more marathons, 50ks, and beyond…without injury for years.
Until now.
I have some serious Achilles issues in both legs now. Haglund’s Deformity and insertional tendinitis in both heels. I am told it is from too much stress on the Achilles for too many years.
At this point, I think the only person I trust is my podiatrist, who recommends nothing but footwear with a good heel-toe drop to reduce strain on the Achilles. He’s pretty certain years of zero drop running eventually caused this.
All a long-winded way of saying I have absolutely no idea that anyone really knows what they’re talking about regarding personal footwear choices. I have no doubt the “traditional” shoe route that was recommended caused certain problems for me. I have no doubt zero drop fixed issues but in turn caused others. Maybe it wasn’t just the shoes/stride and I could have done PT with either model and avoided certain issues. Or maybe some of us are, in fact, NOT born to run ;)
