Orthotic INSOLES
for FLAT FEET

What does having ‘flat feet’ mean?

Flat feet is also called Pes Planus. This is when the arch is low or has collapsed, so most of the bottom of the foot touches the ground when standing. You can check for this with a simple wet footprint test: if you have a normal arch, you’ll see a curved gap along the inner edge of the footprint; if you have flat feet, the print will appear fuller, with little to no gap.

The arch of the foot plays an important role in shock absorption, spreading pressure evenly across the foot, and reducing the risk of injury during activity. It also supports balance and alignment through the ankles, knees, hips, and spine. Estimates suggest that between 20% and 30% of adults have flat feet or low arches, and many don’t experience symptoms until stress from work, weight, activity, or age begins to affect them. “Flexible flat feet” show an arch when sitting but flatten under weight-bearing, while “rigid flat feet” remain flat regardless of position. Rigid and more severe cases require closer clinical attention.

Hereditary flat feet are passed down from parents and are caused by genetics, loose ligaments, or an inherited foot shape. Children have physiological flat feet until around 5–6 years of age, and while most go on to develop an arch later in life, some remain flat-footed into adulthood.

Acquired flat feet, flat feet that develop over time, can result from tendon or ligament injury, pregnancy, arthritis, obesity, prolonged standing, aging, or problems with the posterior tibial tendon. Flat feet can also worsen after an ankle fracture or tendon injury, particularly from the mid-30s onward. Whatever the cause, supportive insoles and orthotics remain the mainstay of conservative treatment for symptom relief.

Imagine the body as a kinetic chain. When the foot rolls too much, those forces travel upward. Without the structural support and shock absorption of a healthy arch, flat feet can cause pain and injury to the ankles, knees, hips, and lower back.

Over-pronation is when the foot rolls inward too much. Flat feet cause the arches to collapse, which can lead to over-pronation and additional strain on the muscles, joints, and ligaments in the foot. This can eventually contribute to knee and lower back pain. As the ankle inverts, the lower leg rotates inward, which can lead to shin splints, patellofemoral pain, IT band strain, and early wear on the knee joint. A large Framingham study found that planus foot posture was associated with increased odds of knee pain and medial knee cartilage damage.

Altered leg alignment may also tilt the pelvis, placing added stress on the hips and lumbar spine. Many people first seek help for back pain after a long shift on their feet at work, or sore shins after a full day walking around a theme park or big box store, only to later discover their feet are the real foundation of the problem. Supportive insoles can help correct the misalignment caused by over-pronation, which may otherwise affect posture and contribute to pain in the knees, hips, and lower back. Arch support plays a critical role in maintaining proper foot alignment, helping to reduce strain on the knees, hips, and lower back during daily activity.

Those with flat feet can experience foot pain, swelling, and difficulty standing or walking for extended periods. This condition can worsen these symptoms over time.

Plantar fasciitis is inflammation of the plantar fascia, the ligament-like band that runs from the heel to the toes. It often causes sharp pain in the heel, especially first thing in the morning.

Over-pronation can lead to muscle fatigue and soreness, plantar fasciitis, tendonitis, and joint alignment problems.

Metatarsalgia (ball-of-foot pain) causes a burning or throbbing sensation under the forefoot, particularly when wearing dress shoes, high heels, or shoes with thin, unpadded soles. Heel spurs, foot fatigue, and bunions are also common. Exercises can help, but correcting alignment with orthotic insoles is usually the foundation for lasting relief.

Insoles, orthotics, and shoe inserts are removable supports that you put in your shoes. While proper insoles don’t cure flat feet, they can improve biomechanical alignment, redistribute pressure, and help relieve pain.

The goal isn’t to force a high arch. It’s to offer support through a supportive arch, reducing over-pronation and spreading pressure more evenly. By stabilizing the heel, controlling over-pronation, and distributing weight more evenly, insoles can help correct biomechanics and relieve strain throughout the lower body.

Footlogics is the happy medium between basic cushioned inserts 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, a deep heel cup, and motion control to help correct over-pronation. Look for flat feet orthotics that offer supportive arch structure, cushioning, and a deep heel cradle to help improve alignment and reduce discomfort. A deep heel cup cradles the heel bone, centres the fatty pad beneath it, and increases heel stability — helping to prevent the foot from rolling inward too much. Look for firm support rather than soft, squishy gel inserts, which don’t provide the structural support flat feet need. Good arch support should feel firm and supportive, without feeling like a hard, uncomfortable lump.

Cushioning, Shock Absorption, All-Day Comfort

Quality insoles provide shock absorption in both the heel and forefoot. People with low arches often need insoles for over-pronation that combine shock absorption with stability, especially for exercise. Proper arch support can improve comfort and performance during physical activity by reducing foot fatigue and improving stride efficiency. They can make hard work boots, athletic shoes, sneakers, and even some zero-drop shoes more comfortable, especially for wide feet that need a roomier 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 shipping, affordability, and a 30-day guarantee.

The best insoles balance support, comfort, shoe fit, activity, and budget. Look for arch support insoles that reduce excessive pronation, which can lead to stress on the muscles, joints, and ligaments of the foot, improving overall foot function.

Conclusion: taking the next step with flat feet insoles

Flat feet and fallen arches are common, can be hereditary or acquired, and often affect more than the sole. Through over-pronation, they can contribute to foot pain, shin splints, knee pain, hip soreness, lower back pain, and daily fatigue.

Medical-grade orthotics are one of the most affordable ways to improve alignment, provide relief, and reduce pain. Explore Footlogics Premium, Comfort, Casual, Sports, Versa, and Active to find the right pair for your shoes, work, sport, and lifestyle.
