Modern Running Shoes and Heel Striking

Phase 1 was a moderate shoe on the “more stability” side of things. I would get injured with regularity.
So then I went to a running shoe store and had them analyze my gait. They “prescribed” a very expensive “high stability” shoe. After a week in those I thought I had permanently damaged my knees. Switched back to moderate shoes.
Then I tried minimal shoes. At first I thought I was hurting my feet, but then I realized that they were just getting a workout for the first time.
I’ve been running in minimal shoes and have been injury free for quite a while now. So that’s my personal anecdote. Not sure I would ever go toward a super minimal shoe, but definitely will stay on shoes with a small heel and minimal arch
So I then switched to New Balance Minimus which are sort of like the five-fingers but with a toe box and thus a bit more protection. These are great and I still have a pair that I sometimes run in. However, I'd periodically bruise the bottom of my foot landing on a sharp rock (looking at you, the Radical Road in Holyrood Park, Edinburgh early one summer morning!).
For the last 5-8 years I have been running in Altra Superiors: a low stack height, zero-drop (between heel and toes) and mostly because they have a rock guard that protects the bottom of your feet. Excellent shoes, I go through about 2 pairs a year and I love them!
Overall, I can highly recommend the "minimal" shoe approach (although maybe not the five-fingers). Go with Altra or Topo something that has zero-drop so you're not heel striking. You don't need/want arch support; the arches are supposed to be strong, support themselves and most importantly (for your knees) act as a primary shock absorber.
BTW: If you're interested in this and "humans as endurance runners", Born to Run by Christopher McDougall is a great read!
One thing I see all the time: women nearly always land well up on the foot, no matter how puffy their shoes are. This does not mean that women always have efficient strides--a lot of the force can go into loft rather than forward motion.
Now I’m really starting to wonder if this could explain why many of my friends can’t run because of bad knees.
