Plantar Fasciitis: What Causes It and What Actually Helps

By the OMNI Clinical Team6 min read

If you step out of bed in the morning and your first few steps feel like a knife in your heel, you're probably dealing with plantar fasciitis. It's one of the most common foot conditions we treat at our Burlington clinic — and one of the most fixable, when treated correctly.

What plantar fasciitis actually is

The plantar fascia is a thick band of connective tissue running along the bottom of your foot, from your heel bone to the base of your toes. It supports the arch and absorbs load when you walk and run.

Plantar fasciitis is degeneration and irritation of this tissue, usually where it attaches at the heel. Despite the "-itis" suffix (which suggests inflammation), the condition is now understood to be more degenerative than inflammatory in chronic cases — similar to tennis elbow.

Why morning pain is so distinct

Overnight, the fascia is in a shortened position with no load. Your first steps in the morning suddenly stretch and load the irritated tissue, producing that sharp heel pain. After a few minutes of walking, the tissue gets a bit more pliable and pain often eases — but it usually returns later in the day or after periods of sitting.

What causes it

Several factors usually combine:

  • Sudden increase in load — new running program, more standing at work, new exercise routine
  • Tight calves — the calf is connected to the plantar fascia via the Achilles tendon. Tight calves load the fascia more.
  • Poor footwear — flat, unsupportive shoes for someone who needs more support, or beat-up running shoes past their lifespan
  • Foot mechanics — flat feet, high arches, or excessive pronation can all increase plantar fascia load
  • Weight gain (sometimes a contributor, especially when combined with other factors)

What actually works

Plantar fasciitis usually responds to a multi-pronged approach. No single intervention is a magic bullet — the combination is what works.

1. Calf and plantar fascia stretching, daily

Calf stretches against a wall, multiple times per day. Rolling the foot over a frozen water bottle or a tennis ball morning and evening. This is one of the highest-leverage habits — and free.

2. Strengthening

The research strongly supports calf raises (especially with the toes elevated) and intrinsic foot exercises. These build the load tolerance of the tissue. Slow, controlled, progressive over weeks.

3. Footwear changes

Get out of unsupportive shoes during recovery. A stiff-soled shoe with a slight heel often feels much better than flats while the tissue heals.

4. Custom orthotics

For many patients, especially those with foot mechanics that are loading the fascia heavily, custom orthotics make a substantial difference. They redistribute load and support the arch in ways generic insoles can't. We do biomechanical assessments and custom orthotics on-site at our Burlington clinic.

5. Hands-on treatment

Manual therapy on the foot, calf, and posterior chain. Acupuncture has reasonable evidence for plantar fasciitis. Both can speed recovery when combined with the home program.

6. Patience

Plantar fasciitis takes time. Most cases improve substantially within 6-12 weeks of consistent treatment, but some take longer. The patients who get frustrated and abandon the program are usually the ones who end up dealing with it for years.

What rarely works on its own

  • Cortisone injections — short-term relief but often doesn't address the underlying cause; some risk of fascia rupture with repeated injections
  • Buying expensive insoles without a proper assessment
  • Rest alone — the tissue needs progressive loading, not just avoidance
  • Generic stretches without addressing footwear and load
