A heel spur — a bony growth on the underside or back of the calcaneus — is one of the most misunderstood findings in podiatric practice. The spur itself is usually not what causes the pain; the pain comes from the inflamed plantar fascia or Achilles tendon at the spur’s attachment site. In our clinic, we routinely see patients who’ve been told they have a heel spur and assumed surgery was inevitable — when in fact the vast majority improve completely with conservative treatment, starting with insoles. The right insole changes the mechanical environment at the attachment site, reducing the inflammatory load that drives the pain cycle.
What Is a Heel Spur and Why Does It Hurt
A heel spur (calcaneal spur) is a calcium deposit that forms at the attachment point of the plantar fascia on the inferior calcaneus (inferior heel spur) or at the Achilles tendon insertion on the posterior calcaneus (posterior heel spur). Inferior spurs are most commonly associated with chronic plantar fasciitis — the spur forms in response to repetitive traction stress at the fascial origin. Interestingly, approximately 50% of people with plantar fasciitis have an associated calcaneal spur visible on X-ray, but spurs are also found in 15–25% of people who have no heel pain at all. This tells us the spur is a marker of chronic fascial stress, not the direct cause of pain.
Pain occurs when the inflamed fascia or bursa adjacent to the spur is mechanically loaded with each step. The characteristic morning pain — worse with the first steps after rest — occurs because the fascia tightens overnight in a shortened position and then is suddenly stretched with weight-bearing, stressing the inflamed tissue at the spur’s attachment. Insoles reduce this stress by supporting the arch (reducing fascial tension) and cushioning the heel (reducing direct impact at the attachment site).
How Insoles Reduce Heel Spur Pain
Insoles address heel spur pain through two distinct mechanisms, and both are necessary for adequate relief:
- Arch support (tension reduction) — the plantar fascia functions like a bowstring between the heel and forefoot; when the arch sags, the bowstring is under greater tension; a semi-rigid arch support physically holds the arch up, reducing the tensile load on the fascia at its calcaneal attachment by approximately 25–40% per step
- Heel cushioning (impact reduction) — the calcaneus absorbs 2–3x body weight with each step; cushioning material under the heel dissipates this energy before it reaches the fascial attachment; the deeper and more conforming the heel cup, the more surface area carries the load and the less stress is concentrated at the spur
Foam insoles (including the thin pads in most athletic shoes) provide heel cushioning only — they have no arch support capability because foam compresses to flat under body weight. This is why patients who add generic cushioning insoles often get partial relief but not resolution. The arch support component requires a semi-rigid or rigid shell material that maintains its geometry under load.
Key Features to Look for in Heel Spur Insoles
- Deep heel cup (18–22mm cup depth) — centers the fat pad under the calcaneus and reduces the concentrated point loading at the spur; shallower cups allow the fat pad to migrate sideways, reducing cushioning effectiveness
- Semi-rigid polypropylene or carbon fiber arch shell — must maintain arch support under full body weight; foam arches collapse within 3–4 hours of standing
- Dual-layer cushioning — firm base layer for arch support + soft top layer for comfort at the heel and forefoot; single-layer foam provides neither
- Full-length vs 3/4 length — full-length insoles provide consistent cushioning from heel to toe and prevent forefoot loading shifts; 3/4 length insoles work better in dress shoes with limited toe box depth
- Anti-shear top cover — reduces the friction-induced inflammation that worsens bursitis adjacent to inferior spurs
Top Insoles for Heel Spurs: Podiatrist Picks
1. PowerStep Pinnacle — Best Overall OTC Insole for Heel Spurs
The PowerStep Pinnacle is our first clinical recommendation for heel spur patients before custom orthotics. Its semi-rigid polypropylene shell maintains arch support across a full day of use — unlike foam alternatives, it doesn’t flatten by mid-afternoon. The deep heel cup (21mm depth) is specifically designed to contain the calcaneal fat pad and reduce point loading at the plantar fascia attachment. The dual EVA foam layers provide top-surface comfort while the shell delivers mechanical correction. In our clinic, we see approximately 60–70% of heel spur patients achieve significant improvement on PowerStep Pinnacle alone within 3–4 weeks.
Best for: Inferior heel spurs, plantar fasciitis with spur, flat-footed patients · Not ideal for: Rigid high-arched feet (cavus foot), posterior heel spur/Haglund’s cases
2. PowerStep Pinnacle Maxx — Best for Severe Overpronation with Heel Spurs
For patients with significant flat feet or severe overpronation driving their heel spur, the Pinnacle Maxx provides a firmer, higher arch profile than the standard Pinnacle. The enhanced medial wing increases the corrective force on the arch, reducing the traction stress on the plantar fascia insertion at the spur site. The heel cup is identical to the standard Pinnacle (21mm) but the arch correction is approximately 30% more aggressive. We recommend the Maxx when patients with moderate-severe flatfoot have only partial response to the standard Pinnacle.
3. Spenco Total Support Max — Best Heel Cushioning
For patients whose heel spur pain is primarily impact-related — worst immediately on heel strike rather than after prolonged standing — the Spenco Total Support Max provides greater heel cushioning depth than the PowerStep line. Its nitrogen-infused polyurethane foam maintains cushioning volume better than standard EVA over extended use periods. We recommend it specifically for patients who are on hard floors (concrete, tile) all day and whose primary complaint is impact pain rather than arch collapse pain.
Dr. Tom’s Heel Spur Insole Protocol
Step 1: PowerStep Pinnacle in a supportive shoe (stability or motion control category) — 4 weeks trial
Step 2: If only partial relief → add a 3mm self-adhesive heel lift under the insole to further reduce fascial tension
Step 3: If still inadequate after 6–8 weeks → custom prescription orthotic with specific heel modification and possible cortisone injection evaluation
Not ideal for: Posterior calcaneal spurs (Haglund’s deformity) — these require a different insole modification with a posterior heel cutout, not a standard heel cup.
When OTC Insoles Aren’t Enough: Custom Orthotics
Approximately 20–25% of heel spur patients in our clinic require custom prescription orthotics after failing OTC insoles. The indications are specific: severe flatfoot deformity where OTC arch height is insufficient, rigid cavus foot where the PowerStep’s standard arch profile doesn’t match the foot’s geometry, bilateral asymmetric spurs requiring different corrections for each foot, or patients who’ve documented 6–8 weeks of consistent OTC insole use without meaningful improvement. Custom orthotics are molded from a neutral suspension cast of the foot, providing corrections that OTC products cannot replicate.
Red Flags: When Heel Spur Pain Needs Urgent Evaluation
⚠️ Schedule an Evaluation If You Have:
- Heel pain that doesn’t improve at all after 4–6 weeks of insole use — may indicate a different diagnosis: stress fracture, nerve entrapment, or systemic inflammatory arthritis
- Constant pain that does not improve with rest — plantar fasciitis characteristically improves with rest; constant pain suggests bone pathology or systemic disease
- Significant posterior heel swelling or warmth — retrocalcaneal bursitis or Achilles paratendinitis requiring anti-inflammatory treatment
- Heel pain associated with morning stiffness in multiple joints — may indicate seronegative arthritis (psoriatic, reactive, ankylosing spondylitis) where enthesopathy causes the spur
- Diabetes with any new heel symptom — heightened infection and ulceration risk requires immediate podiatric evaluation
In-Office Treatment at Balance Foot & Ankle
For heel spur patients who fail conservative insole therapy, our Howell and Bloomfield Hills clinics offer custom prescription orthotics (molded to neutral suspension cast), ultrasound-guided cortisone injection at the plantar fascia attachment (immediate anti-inflammatory effect), extracorporeal shockwave therapy (EPAT — our preferred procedure for chronic cases, stimulates tissue healing without injection), and PRP injection for recalcitrant cases. Surgical heel spur removal is reserved for rare cases with documented failure of 12+ months of conservative care — the vast majority of patients respond to conservative treatment.

Frequently Asked Questions
Do heel spurs go away with insoles?
The heel spur itself — a bony growth — does not go away with insoles. However, the pain from a heel spur almost always responds to conservative treatment. What insoles treat is the inflamed tissue at the spur’s attachment site (plantar fascia or Achilles tendon), not the spur itself. In the vast majority of cases, once the inflammation resolves and the mechanical stress is corrected, the spur becomes asymptomatic and requires no further intervention. Surgical removal of the spur is rarely necessary.
How long does it take insoles to help heel spurs?
Most patients notice meaningful improvement within 2–4 weeks of consistent insole use in appropriate footwear. Full resolution of inflammation typically takes 3–6 months of continuous conservative management. If you’re not seeing any improvement after 4–6 weeks of proper insole use, schedule an evaluation — the diagnosis may need to be reconsidered or additional treatments added.
What is the difference between a heel spur and plantar fasciitis?
Plantar fasciitis is inflammation of the plantar fascia itself — the thick band of tissue running from the heel to the forefoot. A heel spur is a bony growth that forms at the plantar fascia’s attachment on the calcaneus in response to chronic traction stress. The two conditions frequently coexist (about 50% of plantar fasciitis patients have an associated spur on X-ray), but each can occur without the other. The treatment is essentially identical because the pain in both cases comes from the inflamed fascial attachment, regardless of whether a spur is present.
When should I see a podiatrist for heel spur pain?
Schedule an evaluation if: pain has persisted more than 6–8 weeks despite proper insole use; pain is affecting your daily activity or work; you have constant pain that doesn’t improve with rest; you have diabetes, peripheral neuropathy, or inflammatory arthritis; or you’re considering cortisone injection, shockwave therapy, or surgical options. Early diagnosis and proper treatment classification (inferior vs. posterior spur, associated conditions) significantly improves outcomes.
The Bottom Line
The best insoles for heel spurs combine deep heel cups (18–22mm), semi-rigid polypropylene arch shells, and dual-layer cushioning. PowerStep Pinnacle is our first-line OTC recommendation. Pair with a stability shoe and allow 4–6 weeks for evaluation. If only partial relief, add a 3mm heel lift before escalating to custom orthotics. Heel spur pain that doesn’t respond to insoles within 6–8 weeks warrants clinical evaluation — there are highly effective in-office treatments available that are significantly less invasive than surgery.

Frequently Asked Questions
How long do orthotics last?
OTC orthotics: 9-12 months. Custom orthotics: 3-5 years. Replace when the heel cup softens or you no longer feel arch support.
Are OTC or custom orthotics better?
For mild issues OTC works. For chronic plantar fasciitis, severe overpronation, or post-surgical recovery, custom orthotics outperform OTC by a wide margin.
Do orthotics weaken your foot muscles?
No clinical evidence supports this. Orthotics offload painful structures so you can move more, which strengthens muscles indirectly.

Are heel spurs painful?
Heel spurs themselves are not the primary source of pain in most cases. About 70% of people with plantar fasciitis have a heel spur on X-ray, but heel spurs are also found in 15–20% of asymptomatic adults. The pain comes from plantar fascia inflammation at the heel attachment, not from the spur scraping tissue. This is why removing the spur surgically rarely changes outcomes — the fascia degeneration is the underlying problem that drives the pain.
What’s the difference between a heel spur and plantar fasciitis?
Plantar fasciitis is inflammation and degeneration of the plantar fascia ligament at its heel attachment — the most common cause of heel pain. A heel spur is a bony calcium deposit that forms on the bottom of the heel bone. The two frequently coexist, and the spur forms as the body’s response to chronic fascial tension at the heel. Treating the plantar fasciitis resolves the pain in the vast majority of cases; the spur remains on X-ray but becomes asymptomatic.
Does a heel spur require surgery?
Rarely. Heel spur surgery is indicated only when conservative treatment has failed for 12+ months and the specific spur is confirmed as the pain source — not the fascia. This applies to perhaps 2–3% of heel spur cases. Modern surgical approaches include endoscopic plantar fascia release with spur removal; recovery is 6–8 weeks. In our practice, we counsel strongly against spur removal as an isolated procedure because removing the spur without addressing the underlying fascial pathology produces unpredictable outcomes.
How is a heel spur diagnosed?
X-ray confirms the presence and size of a heel spur. A heel spur appears as a bony projection on the calcaneus (heel bone) visible on a lateral foot X-ray. However, finding a spur on X-ray doesn’t confirm it’s causing symptoms — the clinical examination (point tenderness, gait analysis, response to treatment) is equally important. Ultrasound and MRI are used when soft tissue pathology alongside the spur (fascia thickening, partial tears) needs characterization.
Can heel spurs go away on their own?
Bone doesn’t resorb spontaneously in adults without a pathological process. Once a heel spur forms, it’s permanent — but it becomes asymptomatic in the vast majority of patients who treat the underlying plantar fasciitis. The goal isn’t to eliminate the spur; it’s to resolve the fascial inflammation that made it painful in the first place. When the fascia heals, the spur is still there but no longer provokes a pain response.
What treatments work for heel spur pain?
Treatment is essentially identical to plantar fasciitis treatment: daily stretching (plantar fascia and calf), supportive footwear with heel elevation, custom or OTC orthotics, night splints, and activity modification. For persistent cases: corticosteroid injection, shockwave therapy, and PRP. These target the plantar fascia inflammation, not the spur directly — which is appropriate because the fascia is the pain generator. We start with the least invasive options and escalate based on response.
What is posterior heel spur vs. inferior heel spur?
Inferior (bottom) heel spurs form at the plantar fascia attachment on the bottom of the heel and are associated with plantar fasciitis. Posterior heel spurs form at the Achilles tendon insertion on the back of the heel and are associated with Haglund’s deformity (pump bump) and insertional Achilles tendinopathy — a completely different condition requiring different treatment. Both show up on X-ray but are in distinct anatomical locations; the clinical exam identifies which is causing symptoms.
Does shock wave therapy work for heel spurs?
Extracorporeal shockwave therapy (ESWT) shows 60–75% success rates for chronic plantar fasciitis and heel spur pain that has not responded to 6+ months of conservative care. It delivers acoustic pressure waves that stimulate healing and reduce nerve sensitization. Treatment consists of 3–5 sessions over 3–5 weeks; results appear over 6–12 weeks. It’s non-invasive, requires no anesthesia, and has minimal downtime. We offer ESWT in-office as a step between conservative care and surgery.
