Why Plantar Fasciitis Hurts Most With Your First Steps (and What Helps)

The short answer: Plantar fasciitis hurts most with your first steps because the tissue under your foot is thought to tighten while you rest, then gets stretched suddenly when you stand. The pain usually eases within minutes. Stretching, calf and foot strengthening, and activity changes help, though recovery often takes months.

• First-step heel pain, worst after sleep or sitting and easing as you move, is the classic sign of plantar fasciitis [1][2].
• A common explanation is that your feet point down in sleep, which relaxes the plantar fascia, but it is a working explanation and not a proven single cause [3].
• Stretching the plantar fascia and calf has the strongest guideline grade (A), and the 2023 APTA guideline also recommends foot and ankle strengthening [4].
• In one trial of 48 people, slow, heavy heel raises beat stretching at 3 months, but the groups were similar by 6 and 12 months [6].
• More than 90% of patients improve within 10 months of simple treatments, so plan for months, not days [3].
• Heel pain after a fall, a swollen, red, hot foot, or pain you cannot walk on needs a provider's check [8].

The simple answer is that your foot has been still, and the tissue under it does not like being loaded again suddenly.

Plantar fasciitis causes sharp, stabbing pain on the bottom of the foot near the heel. Mayo Clinic says it is usually worst with the first steps in the morning, and it can also flare after long periods of standing or when you get up from sitting. It often eases with movement but may return [1]. The NHS describes the same pattern: worst when you first walk after sleeping or resting, easing once you start moving, and getting worse with prolonged standing, walking or running [2].

The 2023 APTA guideline describes the typical pain as "most noticeable with initial steps after a period of inactivity" [4].

As for why, OrthoInfo (from the American Academy of Orthopaedic Surgeons) offers this explanation: most people sleep with their feet pointed down, which relaxes the plantar fascia, and the pain usually eases after a few minutes of walking [3]. Think of it as a stiff, irritated band that needs a minute to "warm up." This is the usual clinical explanation, though the sources I read do not prove exactly what is happening in the tissue.

What this means: first-step pain does not mean you are making the problem worse by walking. It does mean the tissue is sensitive, and it needs a plan.

The plantar fascia is a thick band of tissue that runs from your heel bone to your toes and supports the arch of your foot. In plantar fasciitis it becomes irritated or inflamed. Mayo Clinic says excess tension can cause tiny tears, and repeated stretching and tearing leads to inflammation. The exact cause varies, and sometimes there is no clear reason [1].

The 2023 APTA guideline adds that the condition may range from inflammatory to degenerative. It accounts for about 15% of foot problems in the general population, is most common between ages 40 and 60, and has no sex bias. Onset is gradual and is usually tied to a change in weight-bearing activity [4].

Several things raise the odds. Mayo Clinic lists these [1]:

• Age 40 to 60.
• High-impact or quick-movement activities, such as running, ballet, high-intensity workouts and jumping sports.
• Foot shape, including flat feet, high arches or an unusual walking pattern.
• Worn-out shoes, or shoes unsuited to the activity.
• Excess body weight.
• Jobs with long hours of standing or walking on hard surfaces, or prolonged desk sitting.

The 2023 guideline names four risk factors: limited ankle flexibility (dorsiflexion, pulling your toes toward your shin), higher body mass index in non-athletes, running, and work that involves weight-bearing, especially with poor shock absorption [4]. OrthoInfo also lists tight calf muscles [3].

Notice the pattern: a recent jump in standing, walking or running often sits behind the pain [4]. That is good news, because load is something you can change.

A provider makes the diagnosis from your story and an exam. The guideline looks for medial (inner) heel pain that is worst with the first steps after inactivity and after prolonged weight-bearing, pain on pressing at the heel where the fascia attaches, and a positive "windlass test" (pain when the big toe is bent upward). It also checks that tests for tarsal tunnel syndrome, a nerve problem, are negative [4].

X-rays may be used to rule out a fracture or arthritis, and an MRI if another problem is suspected [3]. The NHS says to see a doctor if you have tingling or loss of feeling in the foot, or if you have diabetes and foot pain [2].

Please do not self-diagnose from the internet alone. If your pain is constant, is not worse with the first steps, or comes with numbness, get it checked.

Start with the things you can do before your feet touch the floor, then work on the cause.

Stretch before you stand. OrthoInfo suggests a seated plantar fascia stretch in the morning before standing: pull your toes back toward your shin, hold about 10 seconds, and repeat. It also suggests calf stretches, each held about 10 seconds and repeated 20 times per foot [3]. The 2023 guideline gives its strongest grade (A) to stretching the plantar fascia and the calf muscles for short- and long-term pain and function [4]. See our calf stretch.

Choose supportive footwear. The NHS advises shoes with cushioned heels and good arch support, plus insoles or heel pads [2]. OrthoInfo suggests thick-soled, cushioned shoes and replacing worn-out athletic shoes [3]. Try not to take those first steps barefoot on a hard floor. The NHS lists walking barefoot on hard surfaces, high heels, tight pointed shoes, flip-flops and backless slippers as things to avoid [2].

Consider a night splint. For people with consistent first-step morning pain, the guideline gives a strong recommendation (grade A) for night splints worn for 1 to 3 months [4]. OrthoInfo calls them very effective, though they can take getting used to [3].

Think carefully about inserts. The guideline says foot orthoses (shoe inserts) should not be used on their own for short-term pain relief (grade B), but may be used together with other treatments (grade C) [4]. Taping, used with other treatments, is recommended for short-term pain and function (grade A) [4].

Short-term pain relief. The NHS suggests an ice pack wrapped in a towel for up to 20 minutes every 2 to 3 hours, and paracetamol or ibuprofen if needed [2]. OrthoInfo advises not using NSAIDs such as ibuprofen or naproxen for more than 1 month without talking to a primary care doctor [3].

Probably both. Stretching helps, but the 2023 guideline revision puts more emphasis on exercise, including resistance training and heavier-load rehab [5]. It recommends resistance training of the foot and ankle muscles (grade B) [4].

The key trial is from Denmark. In 48 people with ultrasound-confirmed plantar fasciitis, Rathleff and colleagues compared two plans. All participants also received an information sheet and gel heel inserts [6].

• High-load strength training: single-leg heel raises with a towel rolled under the toes, every second day for three months. Each rep took 3 seconds up, a 2-second pause at the top and 3 seconds down. The load rose over time: 3 sets of 12 repetitions, then 4 sets of 10 (adding a backpack with books) after two weeks, then 5 sets of 8 after four weeks [6].
• Stretching: a seated plantar fascia stretch, ten 10-second holds, three times a day [6].

At 3 months, the strength group's Foot Function Index score was 29 points better, which the author called far greater than the minimal relevant difference. By 6 and 12 months there was no difference between the groups [6]. The trial scored 6 out of 10 on the PEDro quality scale, with no blinding of participants, therapists or assessors, and no concealed allocation [7]. The author proposed (but did not test) reasons the loading might work, such as improved tissue load tolerance, ankle flexibility and foot strength [6].

What this means: heavier, slow strengthening may help you feel better sooner, but it is not proven to give a better long-term result than stretching. Using both is reasonable.

A starter routine you can try

This is a common clinical starting point, not the trial protocol. Start well below the trial's loads, and build up over weeks.

1. Morning fascia stretch (seated). Before standing, cross one ankle over the other knee, pull your toes back toward your shin and hold about 10 seconds. Repeat several times, then switch feet [3].
2. Calf stretch. Stand facing a wall with one foot back and the heel down. Lean forward until you feel a stretch in the calf. Hold about 10 seconds, repeat several times per leg [3]. See our calf stretch exercise.
3. Calf raise. Stand holding a counter. Rise slowly onto your toes (about 3 seconds), pause for 2 seconds, then lower slowly (about 3 seconds). Start with both feet and 2 to 3 sets of 8 to 12 repetitions, every other day. As it gets easier, progress to one leg and then add a backpack with weight, as in the trial [6]. See our calf raise exercise.
4. Towel-under-toes calf raise (progression). When the plain calf raise is easy, roll a towel under your toes as in the trial, so your toes bend upward as you rise [6].

Stop if you have sharp pain, the pain is clearly worse the next morning, or you feel tingling or numbness in the foot. Ease back, rest and ask a provider or physical therapist if it keeps happening. Mild muscle soreness is normal.

Kai, Loosn's AI physio coach, can help you pace and progress these around your own heel. It does not replace an assessment if your symptoms are severe, getting worse or unusual.

Think of it as "relative rest." Cut the load that is irritating the foot, but do not stop moving altogether.

OrthoInfo suggests reducing or stopping pounding activities like running or dancing, and choosing low-impact options such as cycling or swimming, which put less stress on the feet [3]. The NHS advises avoiding long periods of walking or standing and says to rest and raise your foot when you can [2]. Mayo Clinic warns that, if you change your walk to avoid pain, you can strain your feet, knees, hips or back [1].

Because the pain often starts after a jump in activity [4], build back up in steps. When pain settles, add back running or long days on your feet a little at a time.

Treat these as second-line. OrthoInfo says injections may be considered if symptoms persist after several months of nonsurgical care, and surgery is generally reserved for people who have not improved after 12 months of aggressive nonsurgical treatment [3]. The physical therapy guideline says therapeutic ultrasound should not be used to enhance stretching (grade A), and treats options such as electrotherapy as second-line [4]. Talk to your provider before paying for any treatment that promises a quick fix.

Expect months. OrthoInfo says more than 90% of patients improve within 10 months of starting simple treatments [3]. The 2023 guideline notes that patients typically have symptoms for more than a year before they seek treatment [4], which is one reason it can feel like a long haul.

Some timing points from the sources:

• Weeks 0 to 2: try self-care. The NHS says to see a doctor if it has not improved within 2 weeks [2].
• Months 1 to 3: night splints, if used, are recommended for 1 to 3 months [4]. The trial's strength program also ran for three months [6].
• Up to 10 months: the point by which more than 90% had improved with simple treatments [3].
• After 12 months of treatment without improvement: surgery may be discussed [3].

If you are not getting better, do not just wait. Ask your provider or physical therapist to reassess.

Emergency: go to the emergency department or urgent care (call 911 if you cannot get there safely) if [8]:

• you cannot put weight on your foot, or have severe pain after a fall or injury
• the foot looks misshapen or deformed
• swelling comes on suddenly after an injury

(Other common emergency numbers are 999 in the UK, 112 across the EU and 000 in Australia.)

Urgent: get seen within a day if [8]:

• the foot or ankle is swollen, red and hot, or you have a fever with foot pain

See a provider soon if [2][8]:

• pain is severe, stops you doing normal activities, is getting worse or keeps coming back
• pain has not improved after 2 weeks of self-care
• you have pain at rest or at night, or pain that wakes you (plantar fasciitis pain is typically worst with the first steps and eases with movement [1][2], so constant pain does not fit that pattern)
• you have tingling or loss of feeling in the foot
• you have diabetes and foot pain
• you had a fall or injury, even if you can still walk

Loosn is not a substitute for assessment when symptoms are severe, getting worse or unusual.

Why does my heel hurt so much with the first steps in the morning? 

Pain on the first steps is the classic sign of plantar fasciitis. OrthoInfo says most people sleep with their feet pointed down, which relaxes the plantar fascia, and the pain usually eases after a few minutes of walking [3]. Mayo Clinic lists first-step pain as the typical pattern [1]. Other heel problems can look similar, so get it checked if it persists.

How long does plantar fasciitis take to go away? 

Often months, not weeks. OrthoInfo says more than 90% of patients improve within 10 months of simple treatments [3]. The 2023 APTA guideline notes that people typically have symptoms for over a year before seeking treatment [4]. The NHS says to see a doctor if it has not improved within 2 weeks of self-care [2].

What is the best stretch for plantar fasciitis in the morning? 

A seated plantar fascia stretch before you stand. OrthoInfo suggests pulling the toes back toward the shin, holding about 10 seconds and repeating, and doing it in the morning before standing [3]. The APTA guideline gives its strongest grade (A) to stretching the plantar fascia and calf muscles [4]. Stretching alone may not be enough.

Is strength training better than stretching for plantar fasciitis? 

At 3 months, one trial of 48 people found slow, heavy heel raises gave much better scores than stretching, but there was no difference at 6 or 12 months [6]. The APTA guideline recommends foot and ankle resistance training alongside stretching [4]. Many clinicians use both. Build up slowly.

Should I rest or keep walking with plantar fasciitis? 

Aim for relative rest, not complete rest. OrthoInfo suggests cutting back on pounding activities such as running and using low-impact options like cycling or swimming [3]. The NHS advises avoiding long periods of walking or standing and walking barefoot on hard surfaces [2]. Return to activity gradually as pain settles.

When should I see a doctor about heel pain? 

See one if pain is severe, stops you doing normal activities, is getting worse or keeps coming back, or has not improved after 2 weeks of self-care. Also go if you have tingling or loss of feeling, or have diabetes [2]. Heel pain after a fall, or a swollen, red, hot foot, needs prompt care [8].

Pacing your stretches and calf raises can be fiddly. Use the free Loosn exercise and rest timer to keep your holds, sets and rest breaks on track, then ask Kai, Loosn's AI physio coach, for a plan built around your heel. Try the timer.
