Here’s another blog by a Mississauga Chiropactor…
Why do Different Foot Strikes Matter?
Here we focus on the difference between heel striking and forefoot striking
Heel striking: The collision of the heel with the ground generates a significant impact. This force sends a shock wave up through the body via the skeletal system.
Forefoot striking: The collision of the forefoot with the ground generates a very minimal impact force with no impact transient.
Therefore, a runner can avoid experiencing the large impact force by forefoot striking properly.

A Note on Midfoot Strikes
Some runners land simultaneously on the ball of the foot and the heel. Midfoot strikes represent a continuum between heel strikes and forefoot strikes, depending on where the centre of pressure is at impact and how stiff the ankle and knee are during impact. One can land softly in a midfoot strike without much impact transient, but some midfoot strikes can generate impact transients like those of heel strikes. However, these forces are distributed over larger surfaces areas, reducing the stress on the foot.
