What supports the arch?
The foot has three arches, but “arch pain” usually means the long inner (medial longitudinal) arch. It is held up by the shape of the bones, strong ligaments, the plantar fascia running from heel to toes, the small intrinsic muscles of the foot and the tibialis posterior tendon, which runs behind the inner ankle and attaches under the arch. When any of these structures is overloaded, the arch becomes painful.
Common causes of arch pain
- Plantar fasciitis: pain under the heel and into the arch, worst in the morning; see plantar fasciitis symptoms.
- Plantar fascia strain: pain along the arch after a sudden increase in walking, running or jumping.
- Flat feet (overpronation): a low arch that can strain the soft tissues.
- High arches (cavus foot): less shock absorption and pressure on the heel and ball of the foot.
- Tibialis posterior tendon dysfunction: pain and swelling on the inner ankle and arch, with the arch gradually flattening.
- Stress fractures of the navicular or metatarsal bones in athletes.
- Midfoot arthritis, often after past injuries.
- Nerve entrapment (tarsal tunnel syndrome): burning or tingling in the arch.
Risk factors
- Sudden increases in training or time on your feet.
- Worn or unsupportive shoes, flip-flops and very flat shoes.
- Tight calf muscles and Achilles tendon.
- Higher body weight and pregnancy.
- Standing on hard floors for long periods.
- Age-related changes in tendons and ligaments.
Relief at home
- Reduce high-impact activities for a while; try cycling or swimming.
- Ice the arch for 15 minutes, or roll it over a frozen water bottle.
- Wear supportive, cushioned shoes with a firm heel counter.
- Use off-the-shelf arch supports or insoles.
- Avoid going barefoot on hard floors.
- Paracetamol or anti-inflammatories briefly, if suitable.
- Return to activity gradually as pain allows.
Stretches and exercises for arch pain
- Calf stretches: straight and bent knee, 30 seconds, 3 times each side.
- Plantar fascia stretch: sit, cross the foot over the opposite knee, pull the toes back toward the shin, 20–30 seconds.
- Towel curls: scrunch a towel with your toes, 2 × 15.
- Short foot exercise: draw the ball of the foot toward the heel to lift the arch without curling the toes, hold 5 seconds, 10 times.
- Heel raises: slowly, on both feet then one, 3 × 10–15.
- Marble pick-ups with the toes.
- Single-leg balance for 30 seconds.
Tibialis posterior tendon problems
The tibialis posterior tendon is the main dynamic support of the arch. When it becomes irritated or weakened, often in women over 40, people with high body weight or after an ankle injury, the arch may gradually collapse, causing pain and swelling along the inner ankle and arch and difficulty standing on tiptoe on that foot. Early treatment with supportive shoes, orthotics, a period of boot or brace use and progressive strengthening can prevent progression. Advanced cases may need surgery. If you notice your foot flattening or rolling inward more than before, get it checked.
When to see a doctor or physical therapist
- Pain that does not improve after two to three weeks of self-care.
- Swelling along the inner ankle or a foot that is flattening.
- Pinpoint bone tenderness, especially in athletes.
- Numbness, tingling or burning.
- Pain after an injury, with bruising or difficulty walking.
- Any foot problem if you have diabetes or poor circulation.
Three common situations
- Runner with arch pain after switching to minimalist shoes: the foot needs time to adapt; go back to more supportive shoes and transition gradually.
- Teacher on her feet all day with aching arches: supportive shoes, insoles, calf stretches and short sitting breaks usually help.
- Woman in her 50s whose foot seems to be getting flatter: tibialis posterior tendon dysfunction should be assessed early.
Choosing shoes for arch pain
- Look for a firm heel counter that does not collapse when squeezed.
- Choose a midsole that bends at the toes but not in the middle of the shoe.
- Ensure enough cushioning for your activity and replace running shoes every 500–800 km.
- Try shoes later in the day when feet are slightly larger.
- Remove the shoe’s insole to fit an arch support if needed.
Key points to remember
- Arch pain often comes from plantar fascia or tendon overload.
- Footwear, arch supports, stretching and strengthening help most people.
- A flattening foot or inner ankle swelling needs assessment.
- Increase activity gradually to avoid flare-ups.
Questions about foot arch pain
These answers are general information and do not replace an examination or individual medical advice.
Why does the arch of my foot hurt when I walk?
Common reasons are plantar fascia strain, plantar fasciitis, flat feet and tendon overload. Unsupportive shoes and sudden activity increases often trigger it.
Do arch supports help?
Yes, for many people. Off-the-shelf insoles are often enough; custom orthotics may help if problems persist.
Should I massage my foot arch?
Gentle massage or rolling a ball under the arch can ease pain and tightness. Avoid pressing hard on very tender spots.
How long does arch pain take to heal?
Mild strains improve within a few weeks. Plantar fasciitis and tendon problems can take several months.
Can flat feet cause arch pain?
They can, but many people with flat feet have no pain. Pain is more likely when the foot is overloaded or the arch is collapsing.
