How Orthotic Insoles Stop Overpronation - Approved NHS Solutions

That nagging shin splint that won't go away. The runner's knee that flares up every time you hit 5km. The plantar fasciitis that returns no matter how many times you rest.

If you're an active person in the UK – runner, hiker, gym‑goer, or simply someone who stands and walks for work – you've probably wondered why these injuries keep coming back.

The answer may start with a single biomechanical issue: overpronation.


What Is Overpronation?

Pronation is a normal rolling movement your foot makes every time you take a step. It helps absorb shock and adapt to the ground. Overpronation is when your foot rolls inward too much – beyond the normal 15 degrees.

Research indicates that overpronation affects approximately 28 to 33% of individuals [3†L6-L9]. For some estimates, as many as 77% of adults overpronate to some degree [3†L26-L30].

When your foot rolls inward excessively, it's not just a foot problem – it's a whole‑body problem.

How Overpronation Sets Off a Chain Reaction

It is excessive pronation that leads to overuse injuries and issues in runners including, but not limited to, shin splints, stress fractures, runner's knee, IT band problems and anterior knee pain [16†L18-L21].

Here's what happens with every step:

  • Your foot rolls inward excessively

  • Your shin (tibia) rotates internally

  • Your knee tracks incorrectly

  • Your IT band gets overstretched

  • Your lower back compensates

This cascade of misalignment creates the perfect storm for repetitive strain injuries [17†L47-L56].


The UK Running Injury Crisis

Nearly two‑thirds of runners surveyed (62%) did not know their running gait, such as whether they overpronate [3†L15-L18].

Most runners are completely unaware they're overpronating. And without proper diagnosis, they keep running – and keep getting injured.


Injuries Caused by Overpronation



Injury How Overpronation Causes It
Shin Splints Repeated tibial rotation from excessive foot motion
Runner's Knee Knee twists inward, kneecap tracks incorrectly
Plantar Fasciitis Excessive arch collapse strains the fascia at the heel
IT Band Syndrome IT band overstretched by inward knee rotation
Stress Fractures Repetitive overload from poor force distribution
Achilles Tendonitis Abnormal foot motion strains the tendon

Firm arch‑support insoles that control overpronation reduce knee stress and support normal kneecap tracking [14†L23-L24].


How Orthotic Insoles Stop Overpronation

Orthotic insoles correct overpronation by:

 Controlling excessive inward roll – A firm arch and deep heel cup stabilise the foot [14†L10-L14]

 Realigning the lower limb – Proper foot position stops the cascade up to your knee and hip [14†L10-L14]

 Reducing stress on knees – Better alignment = better tracking = less pain [21†L25-L28]

 Absorbing shock efficiently – Distributing forces evenly prevents overload

 Preventing injury recurrence – Treat the cause, not just the symptom

ICB GREEN Orthotics are specifically designed to treat patients who exhibit severe pronation, constructed from FIRM Density EVA, providing superior subtalar joint realignment, pronation correction and foundational support of lower limbs [13†L3-L9].


Custom Orthotics vs Off‑the‑Shelf – What Works for Overpronation?

Prefabricated (ready‑made) insoles are often the first line of treatment due to their quick availability and ability to offer real clinical benefit [8†L11-L13]. Many can be heat‑moulded or modified to suit individual patient needs [8†L17-L18].

But – for moderate to severe overpronation, custom orthotics offer:

  • Made‑to‑measure fit for YOUR foot shape

  • Materials selected for YOUR activity level

  • Professional oversight from HCPC‑registered podiatrists

  • Longer lifespan (3‑5 years vs 6‑12 months for OTC)

Interpod Flex foot orthotics offer immediate support for overpronation and foot alignment; flexible yet firm; ideal for fast NHS intervention [8†L19-L22].


How to Know if You Overpronate

Quick at‑home checks:

  • Check your running shoes – is the wear on the inside edge of the sole?

  • Do you have flat feet or a low arch?

  • Do you experience any of the injuries listed above?

  • Does your knee naturally turn inward when you stand?

Definitive diagnosis: A professional gait analysis from a UK podiatrist, using dynamic pressure mapping and video analysis.


The NHS and Orthotics for Overpronation

Insoles are issued by the NHS to manage a wide range of problems, including overpronation [8†L9-L11]. For patients with excessive pronation or flexible flat feet, prefabricated insoles with firm arch support are commonly prescribed [8†L34-L36].

But NHS waiting lists for podiatry have stretched to crisis levels. Private custom orthotics offer a fast, clinically proven alternative.
