What it is
Overpronation refers to an excessive inward roll of the foot during walking or running. It occurs when the arch of the foot collapses too far inward, causing the foot to flatten and rotate toward the ground. While a small amount of pronation is normal and helps with shock absorption, overpronation places extra stress on the foot’s muscles, ligaments, and joints, increasing the risk of injuries.
Common signs include uneven wear along the inner edge of your shoe soles, as well as symptoms such as heel pain, arch discomfort, shin and knee pain, and even hip and low back pain.
Supination describes less‑than‑typical pronation with a tendency to load the outer border. Both terms describe mechanics rather than a disease.
Comfort depends on how the whole limb manages load. Many people with either pattern are symptom‑free. Problems occur when the workload exceeds capacity.
What happens when it occurs
Excessive or insufficient pronation shifts stress to the plantar fascia, tibialis posterior, peroneals, shank, and knee. Training spikes or unsuitable footwear magnify the effect.
Common causes and risk factors
- Calf flexibility and hip strength variations
- Sudden increases in distance, speed, or hills
- Footwear that does not match the task or terrain
- Weakened Foot Support. Weakened tendons and ligaments in the arch can lead to its collapse.
- Low or Flexible Arches. People with naturally low or flexible arches are at a higher risk of overpronation.
- Excess weight can increase the stress on the feet and contribute to overpronation.
Who is most affected
Runners, court and field athletes, retail and healthcare workers on hard floors. Pregnant women.
Typical symptoms
- Arch or medial ankle pain with overpronation
- Outer ankle or fifth metatarsal pain with supination
- Shin or knee ache during training build‑ups
- Hip and lower back pain
When to seek care
If pain persists beyond two weeks, if you change gait to avoid pain, or if night pain develops, it’s also a good idea to see our practitioners if you notice signs of excessive wear on the inside edge of your shoes.
How we diagnose
Gait analysis, single‑leg tasks, calf and hip strength testing, footwear and training load review.
Management
- Match supportive footwear to mechanics and terrain; consider trial stability or neutral shoes, as indicated, with adequate arch support and shock absorption.
- Exercises to strengthen calves, foot intrinsics, tibialis posterior or peroneals as needed.
- Gait cues: increase cadence slightly, narrow excessive step width, quiet landings
- Orthosis trial for persistent symptoms
- Maintaining a healthy weight can help reduce stress on the feet.
Rehabilitation milestones
Phase 1 weeks 0–2: pain control, targeted isometrics, and footwear change trial.
Phase 2 weeks 2–6: heavy slow strength and balance, short‑foot work.
Phase 3 weeks 6–12: plyometric prep, graded run with cadence targets.
Phase 4 weeks 12–16: terrain and speed progressions with monitoring.
Readiness to progress
- Pain ≤2/10 during and the next day
- Calf and target tendon strength within 90 per cent
- Run session at goal cadence completed without flare
Prevention
- Rotate two pairs of suitable shoes
- Plan weekly changes to distance or hills conservatively
- Maintain calf and hip strength
- Maintain a healthy weight
Australia snapshot
- Widespread presentation among recreational runners and court‑sport athletes
- Hard outdoor surfaces and summer road training feature in many cases
- Retail access to gait‑matched footwear and orthoses is broad
Latest insights
Mechanics are adaptable. Small changes in cadence, footwear, and strength have outsized effects.
Use objective checks, such as next-day comfort and repeatable strength, to guide progress.
