I switched briefly around that time to running in vibram five fingers, which trained me how to change my stride and stop heel striking. I no longer wear VFFs but do tend to favor lightweight, minimal heel-drop sneakers, and I still don't heel strike.
Also, the chances of twisting your ankle when your heels are elevated that much from the road is far higher as well.
This sort of automatically limits how far in front of your hips you can land your foot. But then the next step is to change posture and “lean forward” so that it feels like you’re just barely catching yourself with each foot before falling on your face.
The goal is to have your foot land directly under you, then use your quads and glutes to push your foot backward, to create or maintain your forward momentum.
