Quick answer: For firm, structured support in roomy lace-up shoes, our leading choice is the PowerStep Pro Control Full Length. Choose the PowerStep Pro Control WIDE if you have broad feet or wide-fitting shoes. The Footlogics Comfort is a more accessible everyday option, while the Formthotics Run Dual Density is designed for running and sport. If firm orthotics feel uncomfortable, consider the softer Interpod Model C Comfort. For shoes without enough forefoot space for a full-length insert, the Footlogics Casual 3/4 Length is the most versatile alternative.
1. PowerStep Pro Control Full Length — best overall for firm support
The PowerStep Pro Control Full Length is our first choice for people who want noticeable structure beneath a low or flattening arch. It combines strong arch support with a deep heel cup and a 2-degree medial post to support foot positioning inside the shoe. Dual-layer cushioning helps prevent the insole from feeling purely rigid underfoot.
Its full-length shape provides continuous contact from heel to toe, making it most suitable for shoes with removable liners and enough internal depth. Because the support is firm and substantial, it may feel too assertive for someone accustomed to soft, flat insoles.
Why we selected it
Strong arch support for people seeking greater control
Deep heel cup to help stabilise the rearfoot
2-degree medial post for additional structured support
Full-length cushioning for daily walking and standing
Suitable for athletic shoes and roomier casual footwear
Best suited to: Symptomatic flat feet, moderate to marked overpronation, long periods on your feet and people who prefer firm support.
Consider another option if: Your shoes are narrow or shallow, your feet are very wide, or you prefer a soft and forgiving feel.
2. PowerStep Pro Control WIDE — best for wide feet
Standard orthotics can be too narrow through the heel and midfoot for broad feet. When the foot spills over the edge of an insole, the arch contour may sit in the wrong place and the insert can feel uncomfortable even if its support level is otherwise appropriate.
The PowerStep Pro Control WIDE retains the firm arch support, deep heel cup, medial posting and dual-layer cushioning of the standard Pro Control, but is shaped for wide footwear. This makes it a better starting point for broad feet and shoes built on a wider platform.
Why we selected it
Wide profile gives broader feet a more appropriate base
Firm arch support and deep heel cup
2-degree medial post supports foot positioning
Full-length, dual-layer cushioning
Designed for athletic shoes and roomier casual or dress footwear
Best suited to: Wide or broad feet, wide-fit runners, roomy boots and people who want firm support without standing on the edges of a standard-width insole.
Consider another option if: Your shoes are standard width or have limited internal space. A wide orthotic should be paired with suitably wide footwear.
3. Footlogics Comfort — best everyday value
Footlogics Comfort offers a practical balance of support, cushioning and price for everyday use. Developed by Australian podiatrists, this full-length orthotic has a deep heel cup, strong arch contour and a built-in metatarsal raise. Shock-absorbing padding beneath the heel and forefoot adds comfort for walking and standing.
The lightweight EVA construction can be trimmed at the toe with scissors, which is useful when matching the insole to a removable shoe liner. It is designed for lace-up footwear, including runners and work boots.
Why we selected it
Everyday orthotic developed by Australian podiatrists
Strong arch support and a deep heel cup
Heel and forefoot cushioning
Built-in metatarsal raise for additional forefoot support
Trim-to-fit full-length design
More accessible price than the premium structured options
Best suited to: Everyday walking, lace-up shoes, work boots and people trying an over-the-counter orthotic for the first time.
Consider another option if: You dislike metatarsal raises, require firmer control or need an insert for close-fitting dress shoes.
4. Formthotics Run Dual Density — best for running and sport
Flat feet in a running shoe need more than a prominent arch. The insole must also manage repeated impact without making the shoe feel heavy or unresponsive. Formthotics Run Dual Density uses a softer top layer over a firmer supportive base to combine cushioning with control.
Its high-volume profile provides substantial heel and arch contact, while the foam construction helps spread load and absorb shock. It is intended for running shoes, cross-trainers, walking shoes and other sports footwear with enough depth.
Why we selected it
Dual-density foam balances cushioning and support
High-volume heel and arch profile
Designed to help manage excess foot movement during activity
Shock absorption for running and high-impact exercise
Lightweight construction for sports footwear
Suitable for running, gym work, walking and cross-training
Best suited to: Active adults with flat feet, runners who want added in-shoe support and sports footwear with removable liners.
Consider another option if: Your sports shoes are shallow, you need very firm rearfoot control or your symptoms worsen during running. Persistent running pain should be assessed rather than managed by repeatedly changing insoles.
5. Interpod Model C Comfort — best softer option
Not everyone with flat feet tolerates a firm orthotic. The Interpod Model C Comfort is a softer, more cushioned alternative for people who prioritise shock absorption and all-day comfort over maximum control.
Its contoured polyurethane construction supports the natural shape of the foot while providing a more forgiving feel than firmer orthotic models. It occupies more space than a thin dress-shoe insert, so it works best in boots, walking shoes and roomy runners.
Why we selected it
Softer alternative to highly structured orthotics
Contoured shape provides supportive contact
Polyurethane construction offers cushioning and shock absorption
Comfortable for prolonged standing and walking
Durable design for regular use
Particularly well suited to roomy footwear
Best suited to: Sensitive feet, people who find rigid arch supports uncomfortable, long days on hard surfaces and roomy work or walking footwear.
Consider another option if: You need strong correction for marked overpronation or have shoes with little depth.

6. Footlogics Casual 3/4 Length — best for limited shoe space
A full-length insole can crowd the toes or make a correctly sized shoe feel too tight. The Footlogics Casual ends behind the forefoot, leaving the shoe's existing toe cushioning in place and preserving more space at the front of the shoe.
This design makes it a useful option for selected casual shoes and lace-ups where the original liner cannot be removed. As with any 3/4-length orthotic, check that the front edge lies flat and does not create an uncomfortable ridge beneath the foot.
Why we selected it
3/4-length shape preserves forefoot and toe space
Easier to transfer between compatible shoes
Provides arch and heel support without replacing the full liner
Useful when a full-length orthotic makes footwear too tight
Practical option for casual everyday use
Best suited to: Casual shoes, lower-volume lace-ups and footwear without a removable full-length liner.
Consider another option if: You need full-length cushioning, have significant forefoot symptoms or wear very shallow shoes that cannot safely accommodate any additional insert.
How to choose insoles for flat feet
Start with symptoms, not appearance alone
A low arch is not automatically a problem. If your flat feet are comfortable and do not limit activity, you may not need an orthotic. Insoles are most relevant when you are trying to manage symptoms such as arch or heel discomfort, fatigue, instability or soreness during activity.
Match the support level to your tolerance
Firm support may suit someone who wants greater control, but the most rigid option is not always the most comfortable or appropriate. If you have previously struggled with hard orthotics, begin with a more cushioned contour or seek advice before choosing an aggressively shaped device.
Match the insole to the shoe
An effective insole cannot compensate for a shoe that is too narrow, too short or badly worn. Full-length orthotics generally work best when the original liner can be removed. Wider feet need a wide insole and a wide shoe. A 3/4-length model can help preserve toe room, but even this requires adequate depth around the heel and midfoot.
Check where the arch sits
The highest point of the insole should sit comfortably beneath your arch rather than pressing into the heel or forefoot. Select the size from the manufacturer's chart, then check the fit inside the shoe before wearing it for a full day.
Introduce new support gradually
Your feet and legs may need time to adapt to a new contour. Begin with short periods around the house or during easy daily activities, then increase wear time as comfort allows. Remove the insoles and seek advice if they cause persistent pain, pressure, numbness or skin irritation.
Can insoles correct flat feet?
Insoles can support the foot inside footwear and may reduce symptoms for some people, but they do not permanently rebuild the arch or cure flat feet. Research into foot orthoses for adults with flat feet is mixed and varies according to the condition, device and outcome measured. The practical goal is usually improved comfort, load distribution and function—not changing the underlying anatomy of the foot.
Supportive footwear, activity modification, stretching or strengthening may also form part of a management plan. If symptoms are significant or persistent, a podiatrist can assess whether an off-the-shelf insole is suitable or whether you need a different treatment approach.
When should flat feet be assessed?
Arrange an assessment with a podiatrist, physiotherapist or doctor if:
One arch has recently become flatter than the other
You have pain or swelling behind or below the inside ankle
The foot is becoming progressively flatter or more difficult to move
You cannot rise onto your toes on the affected side
Pain is severe, persistent or interfering with walking
You have numbness, weakness, poor circulation, diabetes or a history of foot ulceration
A new insole creates ongoing pain, pressure or skin changes
New or progressive flattening in adulthood can involve the posterior tibial tendon and should not be treated as a simple insole-selection problem.
Frequently asked questions
Are firm or soft insoles better for flat feet?
Neither is universally better. Firm insoles generally offer more structure and control, while softer models prioritise cushioning and may be easier to tolerate. The right choice depends on your symptoms, foot shape, footwear and comfort preference.
Do high arches in an insole give better support?
Not necessarily. An arch that is too high or positioned incorrectly can create pressure and discomfort. A well-fitting contour should feel supportive without digging into the foot.
Can I put orthotic insoles on top of the existing shoe liner?
Usually, a full-length orthotic should replace a removable shoe liner. Stacking it on top can make the shoe too tight and change the fit. If the liner is fixed, a 3/4-length option may be more practical, provided there is still enough heel and midfoot depth.
How long does it take to get used to new insoles?
Some people feel comfortable immediately, while others need a gradual adjustment period. Begin with shorter wear periods and increase them as tolerated. Persistent or increasing pain is a reason to stop and review the fit.
Will insoles stop my feet from pronating?
Pronation is a normal part of walking. Insoles may help manage excessive or poorly controlled motion for some people, but they are not intended to eliminate all pronation.
Can I use the same insoles for running and everyday shoes?
Sometimes, but only if the insert fits both pairs securely and suits both activities. A sports-specific insole may offer a better combination of cushioning, support and shoe compatibility for running.
How we selected these insoles
These six options were selected from The Foot Care Shop range to cover distinct needs rather than rank products solely by firmness or price. We considered arch and heel structure, cushioning, width, length, intended footwear, activity and the practical differences between firm-control, comfort and sports designs.
“Podiatrist-selected” means the products were selected for this guide by The Foot Care Shop's podiatry-informed team. It does not mean that one product is clinically suitable for every person with flat feet. Product availability, specifications and prices may change.
