You’re hobbling out of bed. That first step feels like someone drove a tent stake into your heel. Naturally, you Google "heel pain" and end up staring at grainy, black-and-white pictures of heel spurs that look like menacing little shark fins growing out of a bone. It’s scary. You see that sharp calcium hook and think, Well, no wonder it hurts; I’m walking on a spike.
But here is the weird thing about human anatomy.
Most people who have those terrifying-looking spurs on an X-ray feel absolutely nothing. In fact, studies from institutions like the Mayo Clinic and the American Academy of Orthopaedic Surgeons (AAOS) have shown that about 1 in 10 people have heel spurs, but only 5% of those people actually experience foot pain.
So, why are you looking at pictures of heel spurs in the first place? Usually, it’s because your plantar fascia—the thick band of tissue running across the bottom of your foot—is screaming at you. The spur is often just an innocent bystander that got caught at the scene of the crime.
What a Heel Spur Looks Like on an X-Ray
If you look at actual clinical imaging, a heel spur (or calcaneal spur) looks like a jagged outgrowth. It starts at the front of your heel bone (calcaneus) and points toward your arch. It can be small—maybe just a few millimeters—or it can grow over half an inch long.
When you see these images, you might notice two different "flavors" of spurs. One occurs at the back of the heel, near the Achilles tendon. Doctors call this a posterior heel spur. The other, which is what most people mean when they search for pictures of heel spurs, is the inferior spur on the bottom of the bone.
Don't be fooled by the sharpness in the photo.
While the image looks like a needle poking into your flesh, the spur isn't actually "stabbing" you. Bone is living tissue. The spur is just a shelf of calcium that developed because your body was trying to protect itself from chronic stress. It’s a response to tension, not a weapon your body built to torture you.

The Big Lie: The Spur is the Source of Pain
Honestly, the biggest misconception in podiatry is that the spur is the primary villain.
We used to think that removing the spur was the only way to fix the pain. Surgeons would go in, saw off the bone, and call it a day. But guess what happened? A lot of patients still hurt.
Why? Because the real culprit is usually plantar fasciitis.
The spur is basically a "stress scar." When the plantar fascia is pulled too tight for too long, it tugs on the heel bone. In response, your body sends calcium to that area to reinforce the connection. Think of it like a callous on your hand, but made of bone. If you look at a picture of a heel spur, you are essentially looking at a historical record of how much strain your foot has been under for the last several months or years.
The Anatomy of the Ache
- The Fascia: This is the bowstring. It’s supposed to absorb shock.
- The Bone: This is the anchor.
- The Inflammation: This is why you can’t walk.
When the "bowstring" gets tiny tears, it gets inflamed. That is where the "hot" pain comes from. The spur is just sitting there, chilling. In many cases, if you treat the inflammation of the tissue, the pain goes away even though the spur remains visible on every future X-ray you ever take.
How Doctors Use These Images
When you go to a specialist like a podiatrist, they aren't just looking for the hook. They are looking at the "angle of the dangle," so to speak. They want to see the alignment of your foot bones.
Are your arches collapsing?
Is there evidence of "Haglund’s deformity" (the so-called pump bump)?

A good doctor uses pictures of heel spurs to rule out other things, like a stress fracture in the calcaneus or a rare bone tumor. If the spur is massive and pointed in a very specific way, it might be irritating a nerve—specifically Baxter’s nerve. But that’s the exception, not the rule.
Why Some Spurs Hurt and Others Don't
It largely comes down to the surrounding soft tissue.
If you have a high-quality fat pad under your heel—the natural cushioning we’re all born with—you could have a spur the size of a mountain and never know it. But as we age, that fat pad thins out. This is called fat pad atrophy. Suddenly, there’s less "mattress" between that bony outgrowth and the ground.
Shoes matter too.
If you're wearing flat-as-a-pancake flip-flops or old, dead sneakers, you’re forcing that heel to take the brunt of every step. This compresses the inflamed tissue against the spur. It’s not the spur’s fault; it’s the lack of protection.
Real Examples of Treatment Success
I’ve seen patients who come in clutching their X-rays like they’ve been handed a death sentence. They see the spur and assume surgery is the only path.
That is almost never true.

Take "John," a marathon runner I spoke with recently. His X-ray showed a significant spur. He was devastated. But after six weeks of specific eccentric calf stretches and switching to shoes with a slightly higher "drop" (the height difference between the heel and the toe), his pain vanished. The spur is still there. If he got another X-ray tomorrow, it would look exactly the same. But he’s running 30 miles a week pain-free.
What You Can Actually Do About It
If you’ve been looking at pictures of heel spurs and feeling discouraged, stop. Your feet are not broken. They are just overworked.
Immediate Steps for Relief
- Frozen Water Bottle Roll: Don't just use an ice pack. Freeze a plastic water bottle and roll your arch over it for 15 minutes. This provides cold therapy and a gentle massage to the fascia.
- Night Splints: They look dorkier than a pair of socks with sandals, but they work. They keep your foot in a "dorsiflexed" position while you sleep so the fascia doesn't tighten up overnight.
- The "Great Toe" Stretch: Sit down, cross your aching foot over your knee, and pull your big toe back toward your shin. You should feel a deep stretch in the arch. Hold it for 30 seconds. Do this before your feet even touch the floor in the morning.
- Footwear Audit: If you can bend your shoe in half like a taco, throw it away. You need a stiff midsole that supports the arch. Brands like Brooks, Hoka, or New Balance often have models specifically designed for this kind of structural support.
When to Actually Worry
While most spurs are benign, you shouldn't ignore the pain forever. If you have redness, warmth, or tingling that feels like an electric shock, it might not be a simple spur or plantar fasciitis. You could be dealing with tarsal tunnel syndrome or a systemic issue like rheumatoid arthritis.
Don't DIY a diagnosis based on a Google Image search.
Moving Forward Without Surgery
The medical consensus has shifted heavily toward conservative care. In fact, more than 90% of people with heel pain get better without a surgeon ever touching them. Cortisone shots can help, but they are a "band-aid" that can actually weaken the tissue if used too often.
Focus on the mechanics.
Strengthen your intrinsic foot muscles. Pick up marbles with your toes. Scrunch up a towel on the hardwood floor using only your feet. These "foot core" exercises take the load off the bone and the fascia.
Ultimately, those pictures of heel spurs you see online are just one piece of a much larger puzzle. They are a sign that your foot mechanics have been off for a while, but they aren't a permanent disability. Address the tightness in your calves, support your arches, and give the inflammation time to settle down. Most of the time, the "shark fin" on your X-ray will go back to being a silent, painless part of your anatomy.
Actionable Next Steps
- Check your shoes: Press on the heel counter (the back of the shoe). If it collapses easily under your thumb, it’s not providing enough stability for a symptomatic heel spur.
- Morning Routine: Before getting out of bed, perform 20 ankle circles and 10 "toe-to-shin" stretches to warm up the tissue before it bears weight.
- Consult a Professional: If pain persists for more than three weeks despite rest and stretching, see a podiatrist or physical therapist to check for gait abnormalities or nerve entrapment.
