"It's not just growing pains": a sports medicine doctor explains why your young tumbler's heel keeps hurting even after weeks of rest — and the small fix that gets her back on the floor

The real reason her heel pain keeps coming back after tumbling (and it's not just "growing pains").

By Dr. Laura Bennett — Sports Medicine Physician, longtime consultant for gymnastics, tumbling, and cheer programs

Updated June 2026

There's one sentence I hear almost every week from the parents who reach out through the programs I work with:

"The pediatrician said it's just growing pains and it'll go away on its own. But it's been months, and my daughter is still limping after practice."

That sentence is half true.

It's true that the pain does eventually go away: once the growth plate closes, the problem disappears on its own.

What nobody explains is how much the waiting can cost a girl who trains twenty hours a week — in tumbling passes she skips, landings she "cushions" out of fear, tryouts she postpones, and most of all, in the confidence she loses.

And here's the part that matters most: that waiting is almost never necessary.

In this article I'll tell you, without the runaround, what's actually happening inside your daughter's heel, why rest, ice, orthotics, and stretching keep letting you down, and the one thing that, in my experience, actually changes the game.

Why I stopped telling parents "just wait it out"

I'm Dr. Laura Bennett.

I work in sports medicine for young, growing athletes, and for several years I've served as an outside consultant for gymnastics, tumbling, and cheer programs.

That means something very concrete: I don't only see these girls in an exam room — I see them in the gym, while they train.

I watch them sprint, flip, and land. And I see the exact moment the heel says enough.

For years I gave the same advice you've probably already heard: rest during flare-ups, ice after activity, some calf stretching. Correct advice — but incomplete.

The thing that changed my approach wasn't a research paper. It was a ten-year-old who, after yet another forced break, looked at me and asked her mom: "So can I still do gymnastics or not?"

That's when it hit me that we were treating the symptom beautifully and the child terribly.

From that point on I started asking a different question.

Not "how do I make the pain go away," but "how do I get this girl training without making things worse, while her body finishes growing?"

The answer, as you'll see, is simpler than it sounds. And it isn't a pill.

The real mechanism: a taut rope over an open construction site

Let me explain the biomechanics the way I explain them to families in the gym — with a picture.

Picture your daughter's heel as an open construction site.

At the back of the heel bone (the calcaneus) there's a zone of cartilage still "under construction": the calcaneal apophysis, the spot where the body is still manufacturing new bone. It's tender, alive, a work in progress.

Anchored to that site is a very strong rope: the Achilles tendon, the strongest tendon in the body.

Now, here's what happens during a growth spurt: the bone lengthens fast — sometimes an inch or more in a few months — but the "rope" doesn't lengthen at the same speed. The tendon adapts slowly.

The result: a rope that's suddenly too short, pulled tight over a site that's still fresh.

Every sprint into a pass, every back handspring, every landing is a yank. Not one violent, isolated yank — hundreds of small ones, over and over each practice, right on the most delicate spot.

That's what Sever's disease really is: not some random inflammation, not a bruise. It's the irritation of a growth plate that's being pulled repeatedly by a tendon that's too tight. A mechanical issue, not "a cold in the heel."

And here's the key that explains everything else: in adults, that construction site is closed, the bone is solid.

That's why solutions built for adults, gym compression socks, drugstore heel cups, generic stretching, were designed for a different foot and miss the target.

The 3 reasons nothing has worked so far

Before I get to the solution, let me be honest: what you tried wasn't foolish. It just hit the wrong part of the problem. I can sum it all up in three recurring mistakes.

Mistake 1 — Silencing the alarm instead of removing the cause.

Ice and anti-inflammatories bring down the inflammation and the pain.

But in Sever's, the inflammation is the result of the pulling.

Turn off the alarm and you leave the fire burning.

The moment she goes back to full loads, the yank returns and the pain with it. (And giving ibuprofen before every meet for months isn't a strategy — it's a band-aid on a mechanical problem.)

Mistake 2 — Cushioning underneath, when the pull comes from behind.

Gel heel cups and insoles work under the heel, against the upward impact.

Useful for other kinds of pain, useless here: in Sever's the force pulls from behind, where the tendon anchors.

Padding the sole doesn't ease that tension.

Not to mention, in tumbling you can't even use them, she lands barefoot.

Mistake 3 — Chasing growth with stretching (or just stopping).

Stretching and physical therapy are valuable, and I'd tell you not to drop them.

But during a growth spurt the bone lengthens faster than a tendon can lengthen through exercises: you gain a few millimeters of flexibility, the bone gains a full inch.

And pure rest?

It stops the pain, not the growth: the mismatch is still right there the moment she walks back into the gym. It's the familiar stop → improve → return → pain → stop cycle that so many families repeat four or five times, losing an entire season.

Custom orthotics deserve their own line: they run $250 to $500, require appointments and weeks of waiting, and for a barefoot sport they almost always end up in a drawer.

The common thread across all three mistakes is the same: you're intervening before or after practice, never during.

And the damage happens during.

What actually helps (and why elite programs already know it)

If the problem is a tight rope yanking one specific point during movement, the logical fix is only one thing: support that exact point while she's moving.

Not cushioning underneath.

Not uniform compression across the whole foot.

Not exercises to do at home in the evening.

A targeted stabilization of the calcaneal apophysis, active during the run-in, the jump, and the landing, that reduces the pull just enough to let the "site" heal while the work continues.

This isn't cutting-edge theory. In pro youth academies and elite training centers, this logic — mechanically protecting the growth plates during activity — has been routine for years.

No serious trainer would send a young athlete with apophysitis to load her heel without support.

The paradox is that this culture almost never made it into the pediatrician's office, where the training leans toward disease and medication rather than biomechanics.

So the default answer stays "rest and ice," and the loop never closes.

The sleeve I started recommending (and why it's not "just another gadget")

When I first saw the Sooftie ComfortHeel, I'll admit I was skeptical: the market is full of "kids'" products that are really just scaled-down adult items.

Then I looked at where the compression actually worked. And that's where I changed my mind.

It isn't a sleeve that squeezes everything evenly.

The pressure is graduated and concentrated behind the heel bone, right on the Achilles tendon's attachment — the point that yanks in Sever's. The tension is calibrated for young tissue: firm enough to stabilize, gentle enough for growing skin.

But the thing I've learned to value most, as a clinician, is something else: it's so thin and comfortable that the girls actually keep it on.

I've prescribed excellent orthotics that ended up at the bottom of the bag because they "felt annoying."

And support that stays in the drawer is worth zero, no matter how biomechanically perfect it is.

ComfortHeel goes on barefoot on the mat, under a dance shoe, or inside a cheer shoe, with no bulk.

They forget it's even there.

And that's why they actually use it, every single practice.

What I see happen, in practice

I'm not handing you results from a clinical trial: I'm giving you what I observe, over and over, in the girls I follow.

Emma, 10, competitive tumbling. Pain in both heels for months, tumbling passes cut in half, "braked" landings. Her mom had already spent over $600 on a podiatrist and sessions. First week with the sleeve: the after-practice limp eases. Second week: her first full practice without asking for the ice pack in the car. Fourth week: back to competing with full passes. Her coach, knowing nothing about it, told me she was "attacking her landings again."

Sophia, 12, cheer. Her parents were weighing whether to pull her: she was sleeping badly from the nighttime pain, and it was affecting school. After about three weeks of steady use, the night wakeups were gone. She finished the season.

A 9-year-old gymnast, put on the program's "watch list" for too many absences, was back to every class within two weeks — with noticeably steadier landings.

The thread is always the same: when the pull on the site eases during movement, the irritation finally gets time to settle down — something rest and ice, working outside of practice, simply can't do.

What to expect, week by week (no overblown promises)

I'd rather be cautious, because these families have already been let down enough.

In the first 7 days, what usually changes is the quality of the pain: from a sharp stab to a "feeling of tension." Not the win yet, but the sign that the pulling is easing.

Around the second week, many girls finish practice without asking for ice, and the nighttime pain fades. For a lot of parents, that's the first real "click."

From the third week on, meets and back-to-back practices usually become possible again without setbacks.

One thing to be clear about, though: the sleeve does not "cure" Sever's disease. The growth plate will close on its own schedule, as it should.

ComfortHeel is there to protect that construction site from the yanking during the years when the bone–tendon mismatch is at its peak, so your daughter keeps training and growing instead of sitting on the sidelines.

Timelines vary: some respond in a few days, some in a month.

But if there's no real change within 30 days, it's fair to reassess — which is exactly why there's a 30-day money-back guarantee.

I'll put my own hand on the risk: after everything so many families have already spent, trying something at $34.90 with a full refund is, objectively, the lowest-risk option there is.

Rest and ice, or support during activity?

Boiled down, the comparison is this.

The "wait and see" road (rest, ice, ibuprofen) stops the pain for a few days, then the cycle restarts; she falls behind her teammates; the tab for meds and visits keeps climbing.

The "passive support" road (heel cups, orthotics, generic socks) costs a lot (up to $500 for orthotics), is bulky, often unusable barefoot, and doesn't act where it needs to.

The targeted-stabilization road (ComfortHeel) supports the exact traction point during activity, is thin and usable in every tumbling setting, and is built for growing feet — at $34.90 with a 30-day guarantee.

The difference isn't the price. It's where and when you step in.

A season doesn't come back

In the end, here's the case I make to every parent.

Your daughter's growth plate is going to close either way, whether you do something or not.

The real question is: what happens in the meantime?

On one side there's the waiting road: months of stops and relapses, ground lost against her teammates, and that hard-to-repair thing — the confidence of a girl who stops attacking her landings.

On the other side there's the support road, carrying her through the critical window so she can handle growth and training at the same time.

Every week spent on the couch doesn't come back. Her teammates move forward; she doesn't.

ComfortHeel isn't a miracle promise. It's a mechanical fix — thin and comfortable — that acts where and when it matters: during the movement. It costs less than a single PT session, it's backed by a 30-day guarantee, and in my experience most families see a real change within two to three weeks:

— she finishes practice without limping — the nighttime wakeups disappear — she stops asking for the ice pack in the car — she goes back to telling you about her sport, not her pain

"My 12-year-old dances five days a week and was waking up with heel pain every morning. The gel cups from the pharmacy were useless, you can't even wear them in ballet shoes. This sleeve is thin enough to wear during class and the difference was almost immediate. Wish I'd found it sooner."

Adam R.

"I was skeptical because nothing else had worked for my gymnast. But this wraps the heel perfectly and you can feel it supporting the exact sore spot. She's back to landing her tumbling passes without that little wince every time. If you've got a girl in a high-impact sport, this is a must."
