Shoes Insole – Complete Guide to Best Insoles for Your Shoes

Shoe insoles are an often overlooked solution for improving comfort, correcting fit, and alleviating foot pain. Whether you need extra arch support, better cushioning for standing all day, or a way to fill space in shoes that are too big, the right insole can make a significant difference. With options ranging from basic foam pads to advanced orthotic inserts, understanding the differences is key to choosing the best product for your needs.

The market offers gel, memory foam, and orthotic insoles, each with distinct properties. Brands such as PowerStep, Aetrex, Dr. Scholl’s, and Superfeet dominate the shelves, while retailers from Boots to Screwfix carry varying selections. This guide examines the top-rated insoles, how they address specific conditions, and where to buy them in the UK.

What are the best insoles for shoes?

Here are key insights to keep in mind when selecting shoe insoles:

• Insoles are not just for comfort – they can improve foot alignment and reduce stress on joints.
• The best insole for you depends on your foot type (arch height), activity, and shoe fit.
• Gel insoles offer shock absorption; memory foam molds to the foot; orthotic insoles provide structured support.
• For shoes that are too big, thicker insoles can improve fit, but be careful not to make the shoe too tight.
• Major retailers like Tesco, Screwfix, and Clarks carry basic to mid-range insoles, while specialist sites offer advanced orthotics.

Which insoles work best for shoes that are too big?

Adding an insole is one of the simplest ways to take up extra volume in oversized footwear. The key is choosing a thicker model that fills space without creating uncomfortable pressure points.

Do insoles make shoes smaller?

Yes, they reduce internal volume. In shoes that are too big, this helps achieve a snugger fit. In well-fitted shoes, choose thin insoles to avoid tightness. Memory foam insoles from PowerStep and Aetrex are thicker and add noticeable volume, making them effective for loose shoes. Thinner gel options like Dr. Scholl’s Run Active Comfort work for mild size adjustments.

How to fit insoles in shoes

Remove the original insole if it is removable. Place the new insole inside, ensuring it lies flat. If the insole is too long, trim along the indicated line for your size. Walk a few steps to test comfort – the insole should not shift or cause your foot to feel cramped.

What type of insoles are ideal for boots?

Boots often have minimal built-in cushioning, making insoles a practical upgrade. The best choices for boots combine arch support with a deep heel cup to stabilise the foot inside a tall shaft.

Insoles for boots with arch support

The PowerStep Pinnacle Memory Foam is designed for work and casual boots, offering a rigid arch shape that cradles the heel and reduces strain on the plantar fascia. The Sole Active Medium provides moldable arch support and a zero-drop design, which helps stabilise the foot inside boots, according to OutdoorGearLab.

Are gel or memory foam insoles better for boots?

Memory foam insoles are generally better for boots because they add volume and provide orthotic-level arch support. Gel insoles, while good for shock absorption, are thinner and offer less structural support, making them more suitable for low-profile footwear.

Where can you buy insoles? (Tesco, Screwfix, Clarks)

Availability of insoles varies widely across UK high-street and online retailers. Here is what each store typically offers.

Premium brands like PowerStep, Aetrex, and Superfeet are less common in general retailers and are often sold through specialty stores or online, according to OutdoorGearLab and Consumer Reports. For custom options, services like Stride Soles and SprinSole use phone scanning to create personalised arch supports, as noted on Reddit.

What are the differences between gel, memory foam, and orthotic insoles?

Choosing the right material depends on your primary need – cushioning, support, or a combination. The following comparison highlights the key distinctions.

Gel insoles

Gel insoles are soft, pliable, and designed mainly for shock absorption. They distribute pressure evenly but offer minimal arch support. Aetrex notes that gel is best for high-impact sports and tight footwear where a thin profile is needed. Dr. Scholl’s Massaging Gel line is a common example.

Memory foam insoles

Memory foam conforms to the unique shape of your foot, providing personalised alignment. Brands like PowerStep and Aetrex combine memory foam with rigid arch supports, making them superior for conditions like plantar fasciitis and flat feet, as reported by PowerStep and Aetrex.

Orthotic insoles

Orthotic insoles are firmer and designed to correct foot mechanics. They include rigid arch supports, deep heel cups, and stabiliser caps. Superfeet and Sole are well-known for orthotic offerings. These are often recommended for overpronation, severe arch pain, and long-term foot health.

How do insoles help with foot pain and conditions like plantar fasciitis?

Insoles address foot pain by providing targeted support and cushioning. For plantar fasciitis, models with rigid arch support reduce strain on the plantar fascia ligament. The PowerStep Pinnacle and Aetrex Memory Foam Arch Support both feature a cobra-shaped arch that cradles the heel, according to PowerStep and Aetrex. The Sole Active Medium excels for severe cases with its moldable support, as noted by OutdoorGearLab.

For flat feet, semirigid insoles like the EasyFeet Black Model or Superfeet All-Purpose Support High Arch provide necessary stability. For general foot fatigue, gel insoles can offer temporary relief, though they lack the structural correction needed for chronic conditions.

How have shoe insoles evolved over time?

1. Early era: Insoles were made from felt, leather, or cork. They provided basic cushioning but little arch support.
2. 1970s: Gel insoles were introduced, offering superior shock absorption for athletic footwear.
3. 1990s–2000s: Memory foam became popular, allowing insoles to mold to individual foot shapes.
4. 2010s: Custom 3D-printed orthotics emerged, with brands like Wiivv and SOL using foot scans for personalised fit.
5. Present day: Smart insoles with pressure sensors for gait analysis are entering the market, alongside sustainable materials like bamboo and recycled foam.

What is certain and what remains unclear about shoe insoles?

What background context matters when comparing insoles?

The material choice directly affects performance. Memory foam moulds to the foot but compresses faster than gel, which is more durable and shock-absorbing. Arch support needs vary: low arches (overpronation) require firm support, while high arches benefit from extra cushioning to absorb impact. Retailer reliability also plays a role – Boots and Dr. Scholl’s offer podiatrist-recommended options, whereas general retailers may have a limited selection that focuses on budget products rather than therapeutic quality.

When buying from high-street stores like Tesco or Screwfix, you are more likely to find basic gel or foam pads than advanced orthotics. For superior support, online specialty retailers or dedicated shoe-insole shops are the better choice.

What are authoritative sources and expert opinions on insoles?

“Insoles can be an excellent first-line treatment for mild foot pain, but they are not a substitute for proper footwear or medical care.”

– Paraphrased from podiatric guidance

The NHS offers general foot pain advice and recommends seeing a GP or podiatrist for persistent issues. Which? has reviewed insoles independently, comparing comfort and durability. The American Podiatric Medical Association provides guidelines on selecting appropriate foot products. For UK-specific products, Dr. Scholl’s UK and ShoeInsoles.co.uk offer a wide range.

Summary: What is the best insole for your needs?

For boots, plantar fasciitis, and flat feet, the PowerStep Pinnacle Memory Foam stands out due to its clinically proven arch support and cushioning. The Sole Active Medium is an excellent choice for severe cases, while thinner gel insoles suit tight dress shoes or high-impact activities. If over-the-counter options fail, consider custom insoles from Stride Soles or SprinSole. For a broader selection of footwear, see the Man Shoes – Best UK Formal, Casual & Trainers Guide 2025.
