Heel spurs: what they are, when they matter, and how to choose the right support
A heel spur is a small bony growth on the heel bone. Many people have one and never feel it. When you do have pain, the most common reason is irritation of nearby soft tissue, especially the plantar fascia.
This guide explains what heel spurs mean, what symptom patterns are more likely to be related, and how supportive footwear and orthotic insoles may improve comfort. If your pain behaves more like plantar fascia strain, use the linked guide for targeted self-checks and strategies.
Quick clarity
If someone told you "you have a heel spur," do not assume the spur is the problem. Many spurs show up on x-ray as a sign of long-term pulling or loading at the heel. The pain usually improves when you reduce daily irritation and add consistent support.
The fastest self-check
Locate the tender spot and notice timing. Pain with first steps after rest and soreness along the inner heel edge often points toward plantar fascia irritation. Jump to: Self-check.
What are heel spurs?
A heel spur is a small bony outgrowth on the calcaneus (heel bone). The most common type forms on the bottom of the heel near where the plantar fascia attaches. A less common type forms at the back of the heel near the Achilles attachment.
Spurs are often found incidentally on imaging. That means you can have a spur without pain, and you can have heel pain without a spur. In many cases, the symptoms come from irritated soft tissue around the heel rather than the bone itself.
What a heel spur looks like on an X-ray
This side view X-ray shows the calcaneus (heel bone). A heel spur is a small bony outgrowth that can appear at the bottom of the heel where the plantar fascia attaches. Important: the presence of a spur on imaging does not automatically explain your pain. Many people have heel spurs and no symptoms.
If your symptoms match start-up pain with first steps after rest, that pattern is commonly linked to plantar fascia irritation. See the plantar fasciitis guide for the most relevant self-checks and next steps.
Commonly confused with plantar fasciitis
Plantar fasciitis is irritation and micro-strain in the plantar fascia. It is a soft tissue issue. A heel spur is a bone change that can occur with long-term pulling in the same area. The two often appear together, but treatment is usually aimed at the irritated tissue and the way load moves through the foot.
Common symptoms people call "heel spur pain"
Heel spurs themselves do not always produce symptoms. When people feel pain, it often matches one of these patterns:
Under-heel tenderness
- Localized soreness under the heel, often toward the inner side
- Feels worse on hard floors or after long standing
- Can feel like a bruise when you press the spot
Start-up pain after rest
- First steps in the morning or after sitting feel sharp or stiff
- Improves as you warm up, then returns later after long activity
- Often overlaps with plantar fascia irritation
If your pain is mostly at the back of the heel where the shoe collar rubs, also see the heel pain guide. If symptoms are paired with arch soreness, see arch pain.
Why heel spurs develop
A spur is usually a response to repeated stress at a tendon or fascia attachment point over time. Factors that can increase that stress include:
- Tight calves or limited ankle motion that increases pull on the heel with each step
- Long periods of standing and walking on hard surfaces
- High impact activity increases, especially without gradual build-up
- Unsupportive shoes or worn-out midsoles
- Foot mechanics that concentrate load, such as overpronation or low arches
If you notice inward rolling and uneven shoe wear, the pronation and shoe wear guide can help you connect the dots.
Self-check: simple ways to narrow the pattern
- Map the tender spot. Press under the heel and along the inner heel edge. Note where it is most sensitive.
- Check timing. If the first steps after rest are the worst, plantar fascia irritation is more likely than bone pain.
- Test ankle motion. Tight calves can increase heel stress. If your heel lifts early when you try a calf stretch, stiffness may be part of the picture.
- Look at footwear. Worn heels, collapsed midsoles, or thin insoles often correlate with flare-ups.
Red flags that should be evaluated sooner include inability to bear weight, rapid swelling, fever, numbness or tingling, or a clear injury event.
How orthotic insoles can help
Insoles do not remove a spur. The goal is to reduce irritation in the tissues around the heel by improving how load is shared during walking.
Support and stability
A structured insole can support the arch and stabilize foot motion, which may reduce repeated strain through the plantar fascia for many people.
Pressure distribution
By reducing pressure concentration under the heel, supportive insoles can make long standing and walking feel more tolerable.
Insoles work best when paired with stable shoes. If your shoes are flexible, worn out, or low on cushioning, upgrades there can matter as much as the insert.
Recommended Footminders insoles for heel spurs
Comfort
Best for sneakers, walking shoes, and work boots where there is enough depth for a structured insole.
Kids
Support option for children when footwear alone is not enough. If there is limping, swelling, or pain that keeps returning, consider evaluation.
How to choose based on shoe type
Roomy shoes
Sneakers, walking shoes, work boots, many athletic shoes.
- Start with Comfort
- Remove the factory insole first if space is tight
- Confirm heel feels stable with minimal slip
Tighter shoes
Casual shoes, slip-ons, some dress shoes with less depth.
- Start with Casual
- Confirm toes still have room
- If the shoe becomes cramped, choose a roomier style
Heel spurs, standing jobs, and activity
Many flare-ups correlate with cumulative load rather than one single step. If your day includes long standing, hard floors, or a sudden increase in walking or training volume, your heel tissues may not be getting enough recovery.
- Reduce the specific activity that causes next-day symptom spikes
- Use stable shoes on hard surfaces and avoid thin, flexible footwear during flare-ups
- Progress back gradually rather than trying to catch up quickly
If you are doing targeted mobility work, the plantar fasciitis exercises page includes options commonly used for heel and arch strain patterns.
When to see a professional
- Severe pain or inability to bear weight
- Rapid swelling, redness, fever, or an open wound
- Numbness, tingling, or pain that feels like burning or electrical
- Symptoms that keep worsening despite consistent changes
- No improvement after 2 to 3 weeks of stable footwear, reduced irritation, and supportive inserts
If you have diabetes or known circulation issues, use the diabetic foot care guidance and consider earlier evaluation.

FAQ
Do heel spurs always cause pain?
No. Many heel spurs are painless and are found incidentally on imaging. Symptoms often come from irritation of nearby tissues, especially the plantar fascia, rather than from the bony growth itself.
Is heel spur pain the same as plantar fasciitis?
They are different issues, but they can overlap. Plantar fasciitis is a soft tissue strain pattern. A heel spur is a bone change that can occur in the same region. When symptoms match plantar fascia irritation, strategies usually target the tissue and the way load moves through the foot.
Can insoles remove a heel spur?
Insoles do not remove a spur. For many people, supportive insoles can help by improving stability and reducing pressure concentration, which may make walking and standing more comfortable.
Which Footminders insole should I start with for heel spurs?
Start by matching the insole to shoe space. Comfort is typically best for roomy shoes like sneakers and work boots. Casual is a better starting point when shoes have less depth and you need a slimmer profile.
What else should I change besides inserts?
Stable footwear, avoiding thin flexible shoes during flare-ups, and consistent calf and plantar fascia mobility work are common basics. If your symptoms keep returning, look for the trigger that is adding load, such as hard floors, high weekly mileage, or worn-out shoes.
When should I stop self-care and get evaluated?
Seek evaluation sooner if pain is severe, you cannot bear weight, symptoms are worsening, there is swelling or fever, there are nerve-like symptoms such as numbness or burning, or there is no improvement after a couple of weeks of consistent changes.
