Treatment of Plantar Heel Pain with Orthotic Insoles
That sharp, stabbing pain in your heel when you take your first steps in the morning. The aching that worsens after standing all day. If this sounds familiar, you're one of millions of UK adults suffering from plantar heel pain—a condition that can turn simple activities into agonising ordeals.
The good news? Orthotic insoles offer one of the most effective, drug-free solutions for treating plantar heel pain at its source. This comprehensive UK guide explores how the right foot support can transform your recovery and get you walking comfortably again.
What Is Plantar Heel Pain?
Plantar heel pain means discomfort under the heel, and it has several possible causes. According to the Royal National Orthopaedic Hospital, these include:
-
Plantar fasciitis (the most common cause—see below)
-
Plantar fibromatosis (nodules in the plantar fascia)
-
Plantar fascia tear
-
Stress fracture of the calcaneum (heel bone)
-
Thinning of the fat pad under the heel
-
Subcalcaneal bursitis (inflammation of the fluid-filled sac under the heel)
Understanding the specific cause of your heel pain is essential for effective treatment, which is why professional assessment matters.
What Is Plantar Fasciitis?
Plantar fasciitis is the most common cause of inferior heel pain, literally meaning inflammation of the plantar fascia. The plantar fascia is a strong ligamentous band under your foot that attaches from your heel to your toes. It supports the arch of your foot and is crucial for absorbing strain when you stand, walk, or run .
Plantar fasciitis normally settles over time, but treatment can significantly speed up recovery. The condition affects people of all ages and activity levels, from runners to those who spend long hours on their feet at work.
Typical Symptoms
Inferior heel pain caused by plantar fasciitis may be constant or intermittent. It is usually:
-
❌ Worse first thing in the morning on rising (those first steps are agony)
-
❌ Worse on standing up after periods of prolonged sitting
-
❌ Worse at the start of sporting activity
Patients often describe the pain as "a nail being driven into the heel," or a sharp, aching, or burning sensation. Pain may also occur in the middle part of the foot under the arch .
Risk Factors
Several factors increase your likelihood of developing plantar heel pain:
How Orthotic Insoles Treat Plantar Heel Pain
Orthotic insoles work by addressing the biomechanical issues that contribute to heel pain. They provide:
1. Arch Support
Proper arch support is essential for both flat feet and high arches. For those with flat feet, insoles help support the collapsed arch, reducing strain on the plantar fascia. For high arches, they provide cushioning and help distribute weight more evenly .
2. Heel Cushioning and Shock Absorption
Quality insoles feature heel cushions that absorb impact with every step. This is particularly important when walking on hard surfaces like concrete pavements, which are everywhere in the UK .
3. Pressure Redistribution
Recent research confirms that custom orthotics with heel plugs are more effective at reducing plantar pressure at the heel. A 2025 crossover study found that orthoses with heel plugs significantly reduced average pressure, peak pressure, and pressure contact area at the hindfoot compared to those without .
4. Improved Foot Alignment
By correcting overpronation (feet rolling inward) or supination (rolling outward), orthotics help align your entire lower body, reducing stress on the plantar fascia .
The Evidence: Do Orthotics Really Work for Plantar Heel Pain?
The short answer: yes, when appropriately prescribed.
Research demonstrates that custom-made foot orthoses effectively reduce pain and improve function in patients with plantar fasciitis. A crossover study published in Prosthetics and Orthotics International showed:
-
✅ Foot function index scores significantly reduced with both types of custom orthotics compared to baseline
-
✅ Improvement in pain and increased function after both 4 and 8 weeks of treatment
-
✅ Significant reduction in plantar pressure at the heel with orthoses containing heel plugs
The Royal National Orthopaedic Hospital NHS Trust includes orthotic devices (arch supports and/or heel cushions) as a primary treatment recommendation for plantar fasciitis .
Custom Orthotics vs Over-the-Counter Insoles: What's Best for Heel Pain?
Over-the-Counter (OTC) Insoles
OTC insoles are readily available at pharmacies and online. Products like Dr. Scholl's Advanced Pain Relief Insoles claim to target multiple pain points including plantar fasciitis and heels . FootActive Comfort insoles are another NHS-approved option designed specifically for heel pain and plantar fasciitis treatment .
Pros:
-
Affordable (£20-£50)
-
Immediate availability
-
Good for mild symptoms or prevention
Cons:
-
Generic sizing (not made for YOUR feet)
-
Shorter lifespan (6-12 months)
Custom Orthotics
Custom orthotics are prescribed by HCPC-registered podiatrists and made specifically for your feet using 3D scanning technology and gait analysis .
Pros:
-
Made-to-measure for YOUR exact foot shape
-
Address specific biomechanical issues
-
Premium materials lasting 3-5 years
-
Treat the cause, not just symptoms
-
Professional oversight
Cons:
The Verdict
According to the NHS, both custom and over-the-counter orthotics can be effective. The right choice depends on your specific condition, foot structure, and budget. For chronic or complex plantar heel pain, custom orthotics typically offer superior results .
Comprehensive Treatment Approach: Orthotics + Exercise + Professional Care
For lasting plantar heel pain relief, orthotics work best alongside other strategies.
NHS-Recommended Exercises
The Royal National Orthopaedic Hospital provides specific exercises for plantar fasciitis :
1. Calf Stretch (Knee Straight)
Stand on a step with heels over the edge. Let your body weight gently stretch your heels toward the floor, keeping knees straight. Hold 30 seconds, repeat 3 times, twice daily.
2. Calf Stretch (Knee Bent)
Similar position but with back knee bent—this targets the deeper soleus muscle.
3. Plantar Fascia Stretch
Sit with affected leg crossed over the other. Use one hand to bend toes and ankle up until you feel a gentle stretch under your foot. Hold 30 seconds, repeat 3 times, twice daily.
4. Towel Stretch (Morning Routine)
Before getting out of bed, loop a towel around your foot and pull gently with knee straight. Hold 30 seconds, repeat 3 times. This specifically targets that agonising morning pain .
Additional Self-Care Strategies
-
Rest the foot – avoid prolonged standing/walking where possible
-
Appropriate footwear – wear shoes with extra cushioning and good arch support
-
Ice therapy – apply ice pack (covered with a towel) for 15-20 minutes
-
Weight management – if overweight, losing weight helps prevent future episodes
-
Rolling massage – roll a frozen water bottle or tennis ball under the foot
When to Seek Professional Help
According to the NHS, consult a healthcare professional if:
-
Your pain doesn't improve within a few weeks
-
You experience severe pain during activity
What to Look for in Orthotic Insoles for Plantar Heel Pain
When selecting insoles for plantar heel pain, prioritise:
✅ Firm Arch Support: Essential for controlling overpronation and maintaining alignment
✅ Deep Heel Cup: Stabilises the heel and improves balance
✅ Shock-Absorbing Materials: Look for quality EVA, gel, or advanced polymers
✅ Proper Fit: Insoles must fit your shoes without bunching or sliding
✅ Durability: Quality materials that won't flatten after weeks of use
✅ Breathability: Moisture-wicking materials keep feet dry and comfortable
UK Treatment Pathways: NHS vs Private
