Common Running Stress Points
Key impact zones where runners experience the most strain and injury risk.
Knee & Lower Leg Impact
Heel & Achilles Stress
Ankle Joint Strain
Every kilometre delivers 600 heel strikes. That's 600 chances for plantar fasciitis to take hold.
Running
Running generates heel strike forces of 1.5–3x body weight on every
footfall. At an average pace, that's 600 impacts per kilometre —
each one sending a shock wave from the heel through the plantar
fascia, up the Achilles tendon, and into the ankle joint. On hard
surfaces, that force is returned almost entirely to the body.
Unlike court sports, running offers no recovery between impacts.
The repetitive, unidirectional loading means the plantar fascia
never fully decompresses mid-run. Combine that with foot movement
inside the shoe — which delays proprioceptive feedback on every
landing — and the conditions for plantar fasciitis, ankle
instability, and blister formation are present on every single run.
