Can Kids Get Plantar Fasciitis? Causes, Signs & Treatment

Plantar fasciitis can occur in children, but it is far less common than in adults and is rarely the first diagnosis a pediatrician or sports medicine doctor should suspect. The overwhelming majority of heel pain in kids and adolescents stems from a different condition entirely: Sever’s disease, an irritation of the growth plate at the back of the heel. Understanding why that distinction matters, and how to spot the less typical case where a child’s plantar fascia genuinely is the problem, helps parents avoid both unnecessary worry and missed diagnoses.

Why Most Pediatric Heel Pain Is Not Plantar Fasciitis

When an adult complains of heel pain, plantar fasciitis sits at the top of the list. In children, the picture flips. Sever’s disease (calcaneal apophysitis) is the most common cause of heel pain in pediatric patients, and heel pain in this age group is usually benign and self-limiting.¹ The reason is straightforward: children’s skeletons are still developing, and the growth plate at the back of the calcaneus (the heel bone) is a weak link that absorbs stress before the plantar fascia does. In adults, that growth plate has long since fused into solid bone, so repetitive stress travels instead to the thick band of tissue on the bottom of the foot.

Sever’s disease typically appears between the ages of about 8 and 14, peaking around the pre-teen growth spurt. It tends to affect physically active kids, especially those involved in running and jumping sports. The condition resolves on its own once the growth plate closes, though managing pain in the meantime matters for keeping kids active and comfortable.

When the Plantar Fascia Is Actually Involved

True plantar fasciitis in a child or teenager, while uncommon, is not impossible. It shows up most often in older adolescents whose growth plates have begun to close, removing that “weak link” and shifting mechanical load toward the plantar fascia. Obesity is a well-established risk factor in adults, and overweight adolescents face the same increased load on the arch. Flat feet or very high arches can also predispose a young person to fascial irritation by changing how force distributes across the sole during walking and running.

In younger children whose growth plates are still wide open, genuine plantar fasciitis is rare enough that its presence should prompt a clinician to consider whether something else is going on, such as an inflammatory condition or a structural anomaly. The plantar fascia in a child with Sever’s disease is actually thinner than normal, not thicker, which is the opposite of what you see in plantar fasciitis.² That finding underscores how different the mechanics are in growing feet compared with adult ones.

Signs and Symptoms Parents Should Know

Heel pain in children shares a common complaint regardless of the cause: a kid who limps, avoids running, or walks on tiptoes to keep weight off the heel. Distinguishing between conditions based on symptoms alone is tricky, but there are patterns worth noting.

• Sever’s disease: Pain is usually at the back of the heel, right where the Achilles tendon meets the growth plate. Squeezing the sides of the heel often reproduces it. Pain worsens with activity and improves with rest. It frequently affects both heels.
• Plantar fasciitis: Pain tends to sit on the bottom of the heel, closer to the arch. It is often worst during the first few steps in the morning or after sitting for a long time, then eases somewhat with movement before worsening again after extended activity.
• Enthesitis-related arthritis: Pain at the underside of the heel can look very similar to plantar fasciitis, but it may be accompanied by joint stiffness, swelling in other joints, or morning stiffness that lasts more than half an hour.

Providers need to maintain a high index of suspicion for symptoms that could point to something more serious than a simple overuse injury.¹ Red flags include pain that wakes a child at night, pain that does not respond at all to rest, unexplained fever, or significant swelling. These warrant prompt medical evaluation.

Conditions That Look Like Plantar Fasciitis in Kids

One reason pediatric heel pain gets misattributed to plantar fasciitis is that several other conditions produce overlapping symptoms. Beyond Sever’s disease, two deserve specific mention.

Enthesitis-Related Arthritis

This is a subtype of juvenile idiopathic arthritis where inflammation targets the entheses, the points where tendons and ligaments attach to bone. The calcaneal insertion of the plantar fascia is one of the most commonly affected sites. In one cohort study of children with this condition, tenderness at the plantar fascia insertion was the single most frequent entheseal finding, present in about 39% of patients.³ A separate review reported a similar figure, with plantar fascia insertion tenderness in roughly 38% of affected children.⁴

This matters because enthesitis-related arthritis is a systemic inflammatory disease that benefits from early treatment with disease-modifying medications, not just rest and stretching. A child whose “plantar fasciitis” keeps coming back, moves to different joints, or is accompanied by eye redness should be evaluated by a pediatric rheumatologist.

Tarsal Coalition and Stress Injuries

Tarsal coalition is a congenital condition in which two bones in the back of the foot are abnormally bridged by fibrous tissue, cartilage, or bone. It often goes unnoticed until adolescence, when the bridge begins to ossify and restricts foot motion, causing pain. In a case series of adolescents aged 12 to 19, tarsal coalition was associated with stress fractures in the calcaneus and surrounding bones, producing hindfoot pain that developed gradually over weeks to months.⁵ A teenager with persistent heel pain that doesn’t fit the usual Sever’s profile and doesn’t respond to standard management may need imaging to rule out a coalition or stress injury.

How Pediatric Heel Pain Is Diagnosed

Most causes of heel pain in children do not require imaging or an extensive workup.¹ A physical examination typically provides the answer. The squeeze test (compressing the heel from both sides) is a hallmark for Sever’s disease. Tenderness along the bottom of the heel and into the arch points more toward the plantar fascia. Checking for joint range of motion, swelling, and tenderness at multiple entheseal sites helps screen for inflammatory conditions.

When the clinical picture is unclear or pain persists despite treatment, imaging comes into play. Ultrasound is particularly useful because it can measure plantar fascia thickness without radiation. In adults with plantar fasciitis, the plantar fascia shows significant thickening and abnormal echogenicity on ultrasound, with about three-quarters of symptomatic patients showing abnormal tissue texture.⁶ These findings translate to pediatric cases as well, though normal reference values in children are less well established. Ultrasound research has examined healthy children’s entheses and tendon thickness to help build those reference ranges, but the data set remains thinner than what exists for adults.⁷

X-rays are sometimes ordered but are less helpful than parents might expect. A heel spur, which many people associate with plantar fasciitis, is uncommon in children and not especially useful diagnostically even in adults. MRI is reserved for cases where a stress fracture, tarsal coalition, or bone tumor is suspected.

Treatment for Children With Heel Pain

Here is where the evidence gets frustratingly thin. No randomized clinical trials have examined the treatment of heel or Achilles tendon pain specifically in children and adolescents, so current recommendations rest on clinical experience and a handful of retrospective studies.⁸ That said, the standard first-line approach is straightforward and works well for most kids.

• Activity modification: Reducing the volume or intensity of running and jumping activities, rather than stopping them entirely, is usually enough to bring pain down. Complete rest is rarely necessary and can be counterproductive for an active child’s physical and mental well-being.
• Stretching: Calf stretches and Achilles tendon stretches are standard. Tight calf muscles increase strain on both the growth plate and the plantar fascia, so improving flexibility addresses multiple potential pain generators at once.
• Heel cups or cushioned insoles: These reduce impact on the heel during walking and running. They are inexpensive, widely available, and generally well tolerated by kids.
• Ice and over-the-counter pain relief: Ice after activity and occasional use of ibuprofen or naproxen can help manage flare-ups. Long-term daily use of anti-inflammatories is not recommended for growing children without medical guidance.

Researchers are actively trying to fill the evidence gap. A recent protocol study outlined a trial designed to test whether structured heel-raise exercises combined with pain-monitored activity modification can improve outcomes for adolescents with heel pain. In that design, compliance was defined as performing the exercises at least twice a week, and participants tracked their symptoms, exercise adherence, and activity levels daily.⁹ Until results from trials like this are published, the best available guidance remains conservative management tailored to each child’s activity level and pain.

Do Orthotics Help?

Custom and prefabricated foot orthotics are frequently recommended for heel pain, in both children and adults. The evidence supporting them is weaker than many parents realize. A meta-analysis pooling data from multiple randomized trials found that neither prefabricated nor custom orthotics were better than sham insoles at reducing pain in the short term for plantar heel pain.¹⁰ That analysis was based primarily on adult data, but it tempers the expectation that a $300 custom orthotic will be the solution. Inexpensive over-the-counter heel cups or cushioned insoles provide the same mechanical cushioning at a fraction of the cost. If a child has a structural foot issue like significant flat feet, an orthotic prescribed by a podiatrist might still make sense, but the evidence does not support routine use for every case of heel pain.

How Long Does It Take to Get Better?

For Sever’s disease, the timeline is tied to growth. Symptoms tend to come and go over months to a couple of years, ultimately resolving when the heel’s growth plate closes, usually by age 14 or 15. Flare-ups during sport seasons are common, but the condition does not cause lasting damage to the foot.

For plantar fasciitis in an older adolescent, recovery mirrors the adult experience more closely. Most cases improve within several months of consistent stretching, activity modification, and load management. A small percentage of cases become stubborn and last six months or longer, but surgical intervention is extraordinarily rare in young patients.

Enthesitis-related arthritis follows a different trajectory because it is a chronic inflammatory condition. Early referral to a pediatric rheumatologist is the most important step, since disease-modifying treatment can prevent long-term joint damage. Heel pain in this context is a symptom of a systemic condition rather than a standalone mechanical problem.

When Growing Feet Change the Rules

Much of what adults know about plantar fasciitis from their own experience does not transfer cleanly to a child’s foot. The biomechanics are different. Children with Sever’s disease walk with higher impact and braking forces on the affected foot compared to their unaffected side.² The Achilles tendon in those children is thicker than normal while the plantar fascia is thinner, a pattern you would not see in an adult with a painful foot. These differences mean that treatments optimized for adult plantar fasciitis, like aggressive plantar fascia-specific stretching or cortisone injections, may not be appropriate for a child whose heel pain originates from a growth plate or a juvenile inflammatory condition.

Cortisone injections deserve special caution. They are occasionally used in adults with stubborn plantar fasciitis, but injecting corticosteroids near a child’s growth plate carries a risk of disrupting normal bone development. Most pediatric sports medicine specialists avoid them in this age group. Similarly, more aggressive interventions like extracorporeal shock wave therapy have been studied in adults but have essentially no evidence base in pediatric populations.

The growing foot also changes how you think about footwear. Kids outgrow shoes quickly, and it is easy for a child to spend months in shoes that are too small or too worn out. Shoes that have lost their cushioning or are a half size too tight increase mechanical stress on the heel. For active children, replacing athletic shoes every few months and checking fit regularly is one of the simplest and most overlooked preventive measures. Cleats used in soccer, football, and baseball tend to be especially stiff and offer minimal heel cushioning, making them a common aggravator of heel pain in young athletes.

Red Flags That Warrant Urgent Evaluation

Most pediatric heel pain resolves with patience and conservative care. A few scenarios call for more urgency. Pain that does not improve at all with rest over two to three weeks, or that is getting steadily worse, warrants a visit to a pediatric orthopedist or sports medicine doctor rather than a wait-and-see approach. Night pain, or pain that wakes a child from sleep, is a red flag because overuse injuries like Sever’s disease should not cause pain at rest. Unilateral swelling, warmth, and redness could indicate infection, and fever combined with heel pain in a child needs same-day medical attention.

For adolescents, a heel pain presentation combined with stiffness in the lower back or other joints, especially morning stiffness that improves with movement, should raise the possibility of an inflammatory arthritis. Family history of conditions like ankylosing spondylitis, psoriasis, or inflammatory bowel disease adds to that suspicion. A simple blood test for inflammatory markers and a referral to rheumatology can clarify the picture quickly and spare the child months of ineffective stretching-only treatment.
