Dr. Naughton’s Ultimate Guide to Causes & Relief
"If you're reading this, you likely know the feeling—that sharp, searing pain with your first step out of bed. The pain isn't permanent. Let's walk through exactly what's happening to your feet and how we can fix it together."

1. What Is Plantar Fasciitis?
Plantar Fasciitis (ICD-10 M72.2) is the most common cause of heel pain in adults. It is the inflammation of the plantar fascia—a thick, fibrous band of tissue that runs across the bottom of your foot and connects your heel bone to your toes.
While it feels like tightness, chronic cases involve plantar fasciosis—degeneration or fraying of the collagen fibers. This happens when stress creates micro-tears faster than your body can repair them.
2. Anatomy: The Mechanics of the Strain
Your foot is an engineering marvel. The plantar fascia acts like the string on a bow, creating the tension that maintains the arch of your foot. When you step down, your arch flattens slightly to absorb impact, stretching this "bowstring."
The Overstretch
If your foot flattens too much (overpronation), the ligament is stretched excessively with every single step—thousands of times a day.
The Tear Point
This repetitive pull tears the tissue where it attaches to the heel bone, causing the body to inflame the area to protect it.
Conservative Care Works
Of patients with plantar fasciitis improve with custom orthotics according to the American Academy of Orthopaedic Surgeons.

- Avoids risky, invasive surgery
- Addresses the root mechanical cause
- Prevents long-term recurrence
3. Symptoms & Self-Diagnosis
Plantar Fasciitis has a unique pain signature that distinguishes it from other foot conditions.
First Step Pain
Sharp, stabbing pain when you first get out of bed (Post-Static Dyskinesia).
Start-Up Pain
Pain after sitting for a long lunch or drive, which eases after walking a bit.
Post-Activity Ache
It often feels okay *during* a run, but hurts intensely once you stop and cool down.
Heel Tenderness
Pressing your thumb into the bottom inside of your heel causes sharp pain.
Home Diagnosis: The "Windlass" Test
The same clinical maneuver doctors use to confirm the condition.
- 1 Sit in a chair and cross your affected leg over your knee.
- 2 Pull your big toe firmly backward towards your shin.
- 3 Result: If this reproduces the sharp pain in your heel or arch, it is a positive sign for Plantar Fasciitis.
4. Causes & Risk Factors: Why You?
Biomechanical Causes
- Flat Feet: Arch collapse elongates the foot, pulling the fascia tight.
- High Arches: Rigid feet lack shock absorption, jarring the heel bone.
- Tight Calves: Limits ankle motion, forcing the foot to roll in to compensate.
Lifestyle Factors
- Hard Floors: Standing on concrete/tile for 8+ hours.
- Age: Fat pads thin and tissue loses elasticity after 40.
- Weight: Excess load increases strain on the arch.
5. Comprehensive Treatments
Home Remedies
- Ice Massage: Roll foot on frozen water bottle for 15 mins.
- NSAIDs: Ibuprofen helps manage acute pain (temporary).
- Supportive Footwear: Wear slippers with arch support indoors.
Medical Therapies
- Night Splints: Keeps foot flexed at night to prevent tightening.
- Cortisone: Powerful anti-inflammatory (use with caution).
- Shockwave Therapy: Stimulates blood flow for chronic healing.
3 Essential Stretches for Immediate Relief
Push against wall, leg back, heel flat. Hold 30s.
Why it works: Loosens calf tension pulling on the heel.
Pull toes back toward shin with hand.
Why it works: Directly lengthens the plantar ligament.
Scrunch towel with toes.
Why it works: Strengthens intrinsic arch muscles.
6. The Definitive Treatment: Mechanical Correction
Why Bilt Labs Is The Superior Choice
To truly "cure" Plantar Fasciitis, you must achieve Mechanical Rest. This means stopping the arch from collapsing when you stand.
Soft foam compresses under weight, allowing the fascia to re-tear.
Rigid, custom-molded shell physically blocks the arch from collapsing, allowing the ligament to knit back together.
Ready to Stop the Pain?
If you have these symptoms, you need more than a generic insole. You need a medical device.

Recovering from Plantar Fasciitis is only half the battle; keeping it away is the other.
The Orthotic Advantage: The benefit of using Bilt Labs custom orthotics is that you don't need to buy "orthopedic" looking shoes. You can place your custom support into your favorite sneakers, work boots, or casual shoes, turning almost any footwear into a medical-grade recovery device.
Firm Heel Counter
Back of shoe shouldn't collapse.
Torsional Stability
Shoe shouldn't twist like a towel.
Removable Insoles
Crucial for custom orthotics.
Why Bilt Labs?
We use medical-grade materials that provide the necessary rigidity to support your arch, preventing the plantar fascia from overstretching and pulling on the heel bone with every step.
