Orthotic INSOLES
for FLAT FEET

What does having ‘flat feet’ mean?

Flat feet occur when the medial longitudinal arch of the foot collapses or never fully develops, causing most or all of the sole to make contact with the ground.

There are two main types:

• Flexible flat feet — the arch appears when sitting or standing on tiptoes but flattens under weight-bearing load
• Rigid flat feet — the arch stays absent even when not standing, often causing more significant discomfort

According to a study published in the Journal of Foot and Ankle Research, flexible pes planus may affect between 2% and 23% of adults, depending on the population studied and how it’s measured. NCBI’s overview of pes planus similarly notes that flexible flat feet typically show an arch when the foot isn’t bearing weight, with the arch collapsing once load is applied.

Flat feet can develop from genetics, injury, aging, obesity, pregnancy, arthritis, or weakened tendons. Some people are simply born with naturally low arches; others develop arch collapse later in life.

How Flat Feet Affect the Rest of the Body

The feet are the foundation for the entire body’s alignment. When the arches collapse, the biomechanics of standing and walking shift, and that change tends to cascade upward through the ankles, knees, hips, and lower back.

People with flat feet commonly experience:

• Heel pain
• Arch pain
• Shin splints
• Knee discomfort
• Hip pain
• Lower back pain
• Over-pronation (the foot rolling excessively inward)
• Fatigue during walking or standing

The mechanism behind several of these is well documented:

• Shin splints can develop as excess tibial rotation increases traction on the muscles attached to the shin
• Knee pain (including patellofemoral pain) can occur when altered foot motion changes kneecap tracking during movement. A 2022 meta-analysis found that foot orthoses improved knee function in people with patellofemoral pain, particularly in the short term, as part of broader treatment
• Hip discomfort can follow when collapsing arches encourage internal hip rotation and pelvic tilt
• Low back pain may follow as pelvic alignment and shock absorption change; the Framingham Foot Study found that pronated foot function was associated with higher odds of low back pain in women

How Insoles Help Flat Feet

Insoles, also called orthotics, support the arch, improve foot alignment, and distribute pressure more evenly across the foot.

Arch support. Flat feet lack proper structural support underneath. Insoles help restore arch shape and reduce excessive inward rolling.

Improved alignment. Orthotics help bring the ankles, knees, and hips into more natural alignment, reducing downstream stress on joints and muscles.

Pain reduction. Many people experience reduced heel pain, plantar fasciitis symptoms, and lower back discomfort after switching to supportive insoles.

Better shock absorption. Supportive inserts cushion the foot and absorb impact during walking or running, especially on hard surfaces.

Enhanced stability. Flat feet can affect balance and walking efficiency; orthotics may improve stability and reduce fatigue over the course of a day.

A systematic review found moderate evidence that foot orthoses improve physical function and reduce the energy cost of walking in people with flexible pes planus, supporting insoles as a genuinely useful conservative approach rather than just a comfort measure.

Custom Orthotics vs. Over-the-Counter Insoles for Flat Feet

Over-the-counter insoles are typically sufficient for mild to moderate flat feet symptoms and are far more affordable and accessible than custom devices, available online or in stores rather than requiring a podiatrist appointment.

Custom orthotics, prescribed and molded by a podiatrist specifically to an individual’s foot structure, are usually reserved for severe over-pronation, chronic pain that hasn’t responded to OTC options, tendon dysfunction, or rigid flat feet. They cost significantly more, but some patients find them worthwhile for long-term management of more complex cases.

Popular Insoles for Flat Feet: How They Compare

Brand	Best For	Arch Support Style	Price Range	Key Consideration
Superfeet (Premium/Green)	Daily support, hikers and runners wanting maximum control	High-arch-focused, rigid support with a deep heel cup	Premium	Can feel too firm for sensitive feet or first-time orthotic users
Dr. Scholl’s Custom Fit	General comfort, testing whether insoles help before investing more	Foam-based cushioning with heel cups	Budget (typically under $20)	Less durable and less structured than higher-end orthotics
PowerStep Pinnacle	Moderate overpronation in sneakers, work shoes, or casual footwear	Relatively firm arch support with a pronounced heel cradle	Mid-range	Limited arch height options compared to some competitors
Custom Orthotics	Severe flat feet, rigid pes planus, or complex biomechanical issues	Personalized, molded specifically to the individual foot	High (often $300+)	Requires a podiatrist visit and fitting; not necessary for most mild-to-moderate cases
Footlogics Range	Feet that don’t fit the “average” mold, or anyone needing support across multiple shoe types	Medical-grade orthotic insoles across multiple models, not a single one-size product; options for different arch heights, shoe types, and activities	Mid-range across the full range	TGA-approved, podiatrist-designed; backed by a 30-day money-back guarantee

 

Which Footlogics Insole Fits Your Flat Feet?

• Low to normal arches, everyday wear: Footlogics Premium or Comfort, built for all-day support in standard footwear
• Running, hiking, or sports: Footlogics Sports, with additional shock-absorbing cushioning for repeated impact
• Court sports like pickleball or tennis: Footlogics Active, built for lateral movement and stability
• Dress shoes or low-volume footwear: Footlogics Versa, designed to fit where a full-length insole won’t
• Slip-on shoes without laces: Footlogics Casual, a 3/4-length design that stays secure without laces

Insoles, orthotics and shoe inserts are removable supports that you put in your shoes. While proper insoles do not cure flat feet, they do improve biomechanical alignment, redistribute pressure and relieve pain.
The aim is not to force an arch high. It is to offer support via a supportive arch, reducing over-pronation and spreading pressure more evenly. By stabilizing the heel, controlling overpronation and distributing weight evenly, insoles can correct biomechanics to relieve strain on the entire lower body.

Footlogics is the happy medium between basic cushions and pricey custom orthotics. Custom orthotics are designed to fit precisely to the contours of a person’s feet and offer personalized correction and pressure relief, but most people with flat feet can start with good quality over-the-counter support.

Good insoles include firm arch support, deep heel cups and motion control to correct overpronation. Look for flat foot orthotics that offer low arch support, cushioning, and a deep heel cradle to help improve alignment and reduce discomfort. Deep heel cup cradles heel bone, centers fatty pad and increases heel stabilization. The best insoles for flat feet should focus the fatty pad under the heel bone and stabilize the heel to prevent the foot from rolling inward too much. Look for firm support, not the soft, squishy gel inserts. If you’re looking for an insole, stay away from soft, squishy gel inserts – they don’t provide the structural support flat feet need. Good arch support should provide firm support, but not feel like a hard lump.

Cushioning, shock absorption, all-day comfort

Shock absorption is provided in the heel and forefoot of quality insoles. People with low arches often need insoles for overpronation that are designed with shock absorption and stability for exercise. Proper arch support insoles can improve comfort and performance in physical activities by reducing foot fatigue and increasing stride efficiency. They can make work boots that are hard, athletic shoes, sneakers and even some zero drop shoes more comfortable, especially for wide feet with a wide toe box.

Footlogics offers six insoles for flat feet: Premium, Comfort, Casual, Sports, Versa, and Active. Each is designed with podiatrist and physiotherapist input, international shipping, free USA shipping, affordability, and a 30-day guarantee.

The bottom line

Flat feet can seem like a minor issue, but left unsupported, they can affect alignment and movement patterns throughout the body, particularly for people who are active or spend long periods on their feet. Supportive insoles remain one of the most effective conservative treatments available, whether you choose an over-the-counter option or a custom-molded device, proper arch support can meaningfully improve posture, reduce pain, and restore comfort during everyday activity.

If you’re dealing with persistent or worsening symptoms, it’s worth having a podiatrist or orthopedic specialist assess your feet directly before deciding between an over-the-counter and custom solution.
