Why Does the Bottom of My Foot Hurt When I Walk or Run? Understanding Plantar Fasciitis and How to Fix It



If you’ve ever felt sharp pain in the heel or arch of your foot, especially first thing in the morning or after running, you’re not alone. Plantar Fasciitis is one of the most common causes of foot pain, affecting runners, walkers, and people who spend long hours on their feet. With a structured assessment and targeted rehabilitation, it is highly treatable, and recurrence can often be prevented.

What Exactly Is Plantar Fasciitis?

The plantar fascia is a thick band of connective tissue that runs from your heel to the base of your toes. Its role is to support the arch and absorb forces during walking and running. Plantar Fasciitis develops when this tissue is overloaded, leading to micro-tears, thickening, and pain¹.

Despite the name, the condition is usually degenerative rather than inflammatory. Pain arises from tissue degeneration, mechanical stress, and altered foot biomechanics².

Why Does Plantar Fasciitis Happen?

Common contributing factors include:

  • Weak or tight calf muscles
  • Flat feet, high arches, or abnormal foot mechanics
  • Sudden increases in running, walking, or standing load
  • Poor footwear or worn-out shoes
  • Excess weight or repetitive impact

Identifying your specific contributing factors is crucial for long-term recovery and prevention of recurrence.

The Evidence Behind Plantar Fasciitis Treatment

Research shows that progressive loading, stretching, and strengthening are the most effective approaches:

  • Plantar fascia-specific stretching and calf strengthening can reduce pain by 50–80%³.
  • Foot strengthening exercises improve arch support, function, and load distribution⁴.
  • Orthotics or supportive footwear can reduce strain and improve recovery⁵.
  • Rest or passive treatments alone often provide limited long-term improvement.

How Physio on the Green Can Help

Tailored Rehabilitation and Recovery
Rehabilitation focuses on gradually loading the plantar fascia and restoring foot strength. Exercises include calf raises, toe curls, towel scrunches, balance work, and gait retraining. Manual therapy and guided Pilates complement exercise therapy to restore strength and prevent recurrence.

  • Tight or weak calf muscles
  • Abnormal foot mechanics (flat or high arches)
  • Rapid increase in activity or load
  • Poor footwear or worn shoes
  • Excess weight or repetitive impact

Key Takeaway

Plantar Fasciitis can be painful and frustrating, but it is highly treatable. With a structured, evidence-based physiotherapy plan that addresses foot strength, biomechanics, and tendon load, you can return to running, walking, and standing pain-free.

At Physio on the Green, we combine ultrasound imaging, strength and force testing, gait analysis, shockwave therapy, and personalised rehabilitation programs to ensure complete recovery.
