Symptoms and Causes of Plantar Fasciitis

If you’ve ever stepped out of bed and felt a sharp pain in your heel, you might already be familiar with plantar fasciitis. This common foot condition affects millions of adults and can significantly impact your ability to walk, exercise, or stand for long periods.
Understanding what causes plantar fasciitis—and the symptoms to watch for—can help you catch it early and take action. From recognizing the early signs to knowing how to treat and prevent it, below we'll cover what you need to know to protect your foot health.
Key Takeaways
- Plantar fasciitis is inflammation of the plantar fascia, a thick band of tissue along the bottom of the foot.
- It often presents as stabbing heel pain, especially with the first steps in the morning.
- Risk factors include overuse, tight calf muscles, improper footwear, excess weight, and flat or high arches.
- Supportive shoes, stretches, and rest are effective strategies for both treatment and prevention.
What is the Plantar Fascia?
The plantar fascia is a thick, fibrous band of connective tissue that stretches from your heel bone to the base of your toes. It acts like a shock-absorbing bowstring to support the arch of your foot and help you walk. Every step stretches the plantar fascia slightly, allowing it to store and release energy to help propel you forward.
But just like a rubber band, this tissue can wear out with overuse or poor mechanics. When that happens, tiny tears and inflammation can develop—leading to a painful condition known as plantar fasciitis.
What Are the Symptoms of Plantar Fasciitis?
Plantar fasciitis is one of the most common causes of heel pain. Symptoms usually develop gradually and may worsen over time without proper care.
Here are the most common signs:
- Sharp or stabbing pain in the heel, especially after periods of rest (like getting out of bed in the morning)
- Aching arches that feel worse after long periods of standing, walking, or exercise
- Heel stiffness or tenderness that improves slightly with movement but returns after extended activity
- Pain after long periods of standing, particularly on hard surfaces like concrete or tile
- Tightness in the calves or Achilles tendon, which can add strain on the plantar fascia
This pain is often most intense first thing in the morning or after sitting for a long time. If you experience any of these symptoms, it’s important to address them early—before the condition becomes chronic.

What Causes Plantar Fasciitis?
Plantar fasciitis can have many triggers, but it often comes down to repetitive stress on the plantar fascia. That stress can come from physical activity, lifestyle, or even the shoes you wear.
Here are the most common causes:
- Overuse: Activities like running, walking long distances, or standing for hours can overstretch the fascia, especially without proper rest.
- Improper footwear: Shoes that lack cushioning, arch support, or proper fit can place added strain on the fascia.
- Tight calf muscles: Limited flexibility in the calves and Achilles tendon can pull on the heel and contribute to stress.
- Biomechanical issues: Flat feet, high arches, or pronation abnormalities can alter your stride and increase stress on the fascia.
- Weight gain: Carrying excess weight adds continuous pressure to the fascia, particularly in the heel and arch.
- Age: Plantar fasciitis is most common between ages 40–60, when tissues may become less elastic and more injury-prone.
Each of these causes can either work alone or in combination to overload the plantar fascia. Identifying the root cause is key to choosing the best treatment plan.

How to Manage and Treat Plantar Fasciitis
The good news? Most cases of plantar fasciitis can be managed at home with consistent care. Healing takes time, but many people see improvement within weeks to months using conservative treatments.
Treatment Options
- Stretching: Gentle stretches for the calf, Achilles tendon, and plantar fascia can ease tightness and improve mobility. Our guide to stretching for foot health offers great starting tips.
- Supportive footwear: Wearing shoes with proper arch support and cushioning—like KURU’s patented designs—can help redistribute pressure and reduce pain.
- Orthotics: Shoe inserts can support high or flat arches and relieve pressure at the heel.
- Ice and rest: Applying ice for 15–20 minutes at a time and avoiding aggravating activities can reduce inflammation.
- Massage: Use a tennis ball, lacrosse ball, or frozen water bottle to roll out the foot and help relax the fascia.
- Night splints: These help keep the fascia gently stretched overnight, reducing morning pain.
Prevention Strategies
- Daily foot care: Stretch your calves and plantar fascia regularly to reduce tightness.
- Choose supportive shoes: Avoid flat shoes or worn-out soles. Discover how to choose the right fit.
- Strengthen your feet: Try towel scrunches, marble pickups, and toe flexor exercises to build foot strength.
- Limit barefoot time on hard floors: Use cushioned mats or wear supportive shoes at home, especially on tile or hardwood.

Why Footwear Matters for Plantar Fasciitis
Footwear plays a foundational role in both treating and preventing plantar fasciitis. The right pair of shoes can help reduce heel strain, absorb shock, and encourage better alignment with every step.
Ill-fitting or unsupportive footwear, on the other hand, can worsen symptoms by increasing pressure on the plantar fascia. Shoes that are too flat, too tight, or lacking in cushioning can all contribute to the development or worsening of this condition.
Instead, choose shoes that:
- Cradle and cushion the heel
- Support your foot’s natural fat pad
- Promote healthy alignment through the arch and heel
- Absorb shock to ease pressure on joints and connective tissue
Whether you're heading into the office, walking the dog, traveling, or spending time in the kitchen, footwear that offers this kind of support can make daily activities more comfortable and sustainable.

FAQs
-
How long does plantar fasciitis take to heal?
Most people recover from plantar fasciitis within 6 to 12 weeks using conservative treatment like stretching, ice, and supportive footwear. However, more severe or chronic cases can take up to 6 months or longer. Healing time depends on the consistency of care, activity levels, and underlying risk factors.
-
Does plantar fasciitis get worse before it gets better?
Sometimes. During early treatment—especially when using massage or stretching—discomfort can temporarily increase as tight tissues are released. This is common and typically resolves as the plantar fascia begins to heal. If pain intensifies or persists, consult a healthcare provider.
-
Can I walk with plantar fasciitis?
Yes, but it's important to modify your activity. Walking short distances in supportive shoes may actually aid circulation and recovery. Avoid barefoot walking and prolonged standing, which can worsen symptoms. If walking causes sharp or increasing pain, reduce activity and rest your feet.
-
Is it okay to exercise with plantar fasciitis?
Yes—low-impact exercises are often recommended. Activities like swimming, cycling, or using an elliptical trainer can help you stay active while reducing stress on your feet. Avoid high-impact workouts like running or jumping until pain has subsided and flexibility improves.
-
What kind of shoes should you wear for plantar fasciitis?
The best shoes for plantar fasciitis offer a combination of arch support, heel cushioning, shock absorption, and a proper fit. Look for designs that reduce pressure on your heels, stabilize the arch, and encourage healthy alignment. Avoid flat shoes or worn-out sneakers.
-
Is walking barefoot bad for plantar fasciitis?
Generally, yes. Walking barefoot—especially on hard surfaces like tile or hardwood—removes arch and heel support and increases strain on the plantar fascia. For optimal recovery and prevention, wear cushioned, supportive shoes or recovery sandals, even indoors.
-
When should I see a doctor for plantar fasciitis pain?
If your symptoms don’t improve after several weeks of rest, stretching, and footwear changes, it’s time to see a healthcare provider. You should also consult a doctor if pain worsens, interferes with daily activities, or you experience swelling or numbness in the foot.
-
Can plantar fasciitis become a long-term condition?
Yes, if left untreated, plantar fasciitis can become chronic and significantly limit mobility. Ongoing inflammation may lead to additional complications like heel spurs, gait changes, or pain in the knees and hips. Early intervention and consistent care help prevent long-term issues.
