How to Pick the Right Insoles: A Simple Step-by-Step Guide from Our Plymouth Fitters

This guide explains how our team at Foot Solutions Plymouth assesses and fits insoles, helping you make an informed choice whether you are considering over-the-counter support or custom orthotics.

If you are unsure where to start, our book a free foot assessment with gait analysis at our Royal Parade store can remove the guesswork and help you find the most appropriate solution.

Think about what you feel, where you feel it, and when it tends to occur. Common complaints include:

• Sharp heel pain first thing in the morning
• Burning beneath the ball of the foot
• Aching arches after long walks
• Knee, hip, or lower back discomfort after prolonged standing

While supportive insoles may help reduce strain and improve comfort, they are not appropriate for every condition. If you experience sudden swelling, cannot bear weight, notice numbness, develop signs of infection, or have diabetes with new foot symptoms, seek prompt medical advice before relying on insoles alone.

Even the best insoles will perform poorly inside unsuitable footwear.

Before choosing an insole:

• Make sure the shoe has a removable factory footbed.
• Check that the shoe has enough depth to accommodate additional support.
• Look for a firm heel counter and a roomy toe box.
• Replace excessively worn or distorted shoes, as they can undermine the effectiveness of any insole.

Supportive footwear and supportive insoles work together to provide the best results.

Your arch should be supported, not forced into an unnatural position.

• Lower arches often benefit from moderate contouring and added stability.
• Medium arches generally perform well with balanced support.
• Higher arches usually require greater contact and enhanced cushioning to distribute pressure.

A simple wet-footprint test at home may provide a rough indication of arch height, but it is not a diagnostic tool. Professional assessment using gait analysis and foot scanning provides a far more accurate picture of how your feet function during walking.

A structured heel cup helps stabilise the rearfoot and may reduce stress on surrounding tissues, including the plantar fascia.

If your heel slips inside the shoe or you feel unstable while walking, choose an insole with a deeper heel cup where possible. Dress shoes with limited depth may require slimmer orthotic-friendly designs.

Many people assume softer is better, but excessive softness often provides comfort without meaningful support.

In general:

• Firmer materials improve stability and alignment.
• Cushioned top layers help reduce pressure and improve comfort.
• A supportive base with moderate cushioning is often preferable to a very soft foam insert, particularly for people with plantar heel pain or those who spend long hours on their feet.

Aim for the firmest insole that remains comfortable after 10–15 minutes of walking.

You can learn a surprising amount by observing yourself.

Try:

• Recording yourself walking from behind using your phone.
• Looking for uneven heel movement or excessive inward rolling.
• Examining wear patterns on old shoes.
• Testing your balance by standing on one leg.

These observations provide useful clues but should not be considered a diagnosis. Professional gait analysis combines observation with pressure mapping and digital scanning for a more complete assessment.

Many people benefit from high-quality over-the-counter arch support insoles, particularly for mild or early symptoms.

When trying them:

• Remove the factory insole before fitting.
• Never stack multiple insoles together.
• Ensure the device sits flat inside the shoe.
• Wear them consistently during the adaptation period.

If symptoms persist despite appropriate footwear and supportive insoles, or if your foot mechanics are more complex, custom orthotics may provide a more tailored solution.

Even well-fitted insoles require an adjustment period.

A typical progression might be:

• Days 1–2: 1–2 hours daily
• Days 3–4: 2–4 hours daily
• Days 5–7: Increase gradually toward full-day wear

Some mild muscle fatigue or awareness of new support can be normal while your body adapts. However, sharp pain, numbness, excessive rubbing, or worsening symptoms should be reviewed by a professional.

Most supportive insoles can be moved between similar pairs of footwear.

For best results:

• Use shoes with removable footbeds.
• Ensure comparable depth and internal volume.
• Keep left and right inserts correctly positioned.
• Confirm the heel sits fully within the heel cup after installation.

Different footwear styles, particularly sandals or formal shoes, may require dedicated orthotic-friendly designs.

Many fitting problems come down to simple errors:

• Stacking multiple insoles together
• Using supportive insoles inside worn-out shoes
• Choosing cushioning without structural support
• Selecting an arch profile that is too aggressive
• Skipping the adaptation period
• Continuing to use insoles long after they have become compressed or worn

Inspect your insoles regularly and replace them if they lose their shape or no longer provide adequate support.

When appropriately selected and fitted, supportive insoles and custom orthotics can help redistribute pressure, improve stability, and reduce strain on various structures within the foot and lower limb.

Many people experience meaningful symptom relief and improved comfort, particularly when insoles are combined with suitable footwear and activity modifications. Outcomes vary depending on the individual and the underlying condition, so assessment and proper fitting remain important.

Consider custom orthotics if:

• Symptoms continue despite good supportive footwear and quality insoles.
• You have significant asymmetry or unusual foot structure.
• You have arthritis or other complex biomechanical concerns.
• Your work or sport places unusually high demands on your feet.

At Foot Solutions Plymouth, custom orthotics are designed using 3D foot scanning and pressure analysis to match your unique movement patterns and pressure distribution.

Lifespan depends on materials, activity levels, body weight, and daily use. Many custom orthotics remain effective for several years when properly maintained, although top covers may need replacing periodically.

Annual reviews are recommended, particularly if your symptoms change or your activity levels increase significantly.

How do I pick the right insoles?

Choose insoles based on your symptoms, footwear, arch profile, and activity level. A supportive heel cup and appropriate arch contour are generally more important than extra cushioning.

Many people experience reduced discomfort and improved function when insoles are correctly matched to their needs and combined with appropriate footwear.

If you would like personalised guidance, book a free foot assessment at Foot Solutions Plymouth. Bring along the shoes you wear most often so we can evaluate how they work with supportive insoles or custom orthotics.

During your appointment, we can review your symptoms, assess your gait, scan your feet, and recommend practical solutions tailored to your daily activities.
