Podiatry & Foot Health

Healthy feet make a difference to the way people stand, walk, exercise and manage everyday life. Foot problems can start with something as simple as poor-fitting shoes, but they can also be linked with joint problems, injury, diabetes, circulation, nerve changes or the way the foot moves.

Podiatry focuses on the feet, ankles and lower limbs. It can involve skin and nail problems, pain, walking difficulties, sports injuries and changes in foot health caused by long-term medical conditions. Looking at the cause of a problem is often more useful than treating the sore area alone.

Why Foot Health Matters

Feet carry the body’s weight through thousands of steps each day.

Small changes in the foot can affect the ankle, knee, hip and sometimes the way a person moves through the whole body.

Foot problems can also reduce activity. Someone who develops heel pain may start walking less, which can then affect fitness, weight, strength and general health.

This is why persistent foot pain should not always be treated as a minor inconvenience.

What Podiatry Covers

Podiatry deals with a wide range of problems, including:

• heel pain
• arch pain
• bunions
• corns and calluses
• ingrown toenails
• fungal nail changes
• plantar warts
• flat feet
• ankle and foot injuries
• pain during walking or running
• diabetic foot health
• circulation concerns
• changes in sensation
• footwear problems
• children’s foot development

The right approach depends on what is causing the problem and how much it affects movement or daily life.

Heel Pain

Heel pain is one of the most common foot complaints.

It can develop gradually or begin after a change in activity.

Possible causes include:

• plantar fasciitis
• Achilles tendon problems
• heel pad irritation
• stress injury
• arthritis
• nerve irritation
• unsuitable footwear

The location of the pain can provide useful clues.

Pain under the heel has different common causes from pain at the back of the heel.

Plantar Fasciitis

The plantar fascia is a strong band of tissue that runs along the bottom of the foot.

Plantar fasciitis develops when this tissue becomes irritated.

A common pattern is pain under the heel that is worse with the first steps after getting out of bed or after sitting for a long time.

The pain may improve as the foot warms up and then return after prolonged standing or activity.

Contributing factors can include:

• sudden increase in walking or running
• long hours standing
• tight calf muscles
• changes in footwear
• body weight
• foot mechanics

Recovery can take time because the plantar fascia is loaded every time a person walks.

Achilles Tendon Pain

The Achilles tendon connects the calf muscles to the heel.

Pain may develop in the tendon itself or near where it attaches to the heel bone.

Common triggers include:

• running
• jumping
• sudden increase in training
• hills
• tight calf muscles
• reduced ankle movement

Achilles problems often respond better to gradual strengthening than to complete rest for long periods.

The exact approach depends on where the tendon is painful and how long symptoms have been present.

Bunions

A bunion is a change in the position of the big toe joint.

The big toe gradually moves towards the smaller toes while the joint at its base becomes more prominent.

Bunions can cause:

• pain
• redness
• difficulty with shoes
• pressure on nearby toes
• reduced movement in the joint

Genetics play a strong role.

Footwear can make symptoms worse but is not always the original cause.

Wide shoes with enough room around the toes can often improve comfort even though they do not reverse the underlying joint change.

Corns and Calluses

Corns and calluses develop when the skin is exposed to repeated pressure or friction.

Calluses usually form as broader areas of thickened skin.

Corns are smaller and can press more deeply into the skin.

Common locations include:

• the ball of the foot
• tops of the toes
• between the toes
• edges of the foot
• the heel

Removing thick skin may relieve discomfort, but the pressure causing it also needs attention.

Otherwise, the problem often returns.

Ingrown Toenails

An ingrown toenail develops when the edge of the nail grows into or presses against the surrounding skin.

It most commonly affects the big toe.

Possible symptoms include:

• pain
• redness
• swelling
• tenderness
• discharge when infection develops

Causes can include:

• cutting nails too short
• rounding the corners deeply
• tight footwear
• injury
• naturally curved nails

Mild cases may improve when pressure is reduced and the nail is allowed to grow normally.

Repeated or infected ingrown nails may need more direct treatment.

How to Cut Toenails

Toenails are generally easier to manage when they are cut fairly straight across rather than deeply curved at the sides.

Cutting too far into the corners can encourage the surrounding skin to grow over the nail edge.

Nails that are very thick, painful or difficult to reach may need more careful management, particularly in people with diabetes, poor circulation or reduced sensation.

Fungal Toenails

Fungal nail infection can cause toenails to become:

• thick
• yellow or brown
• brittle
• crumbly
• distorted
• separated from the nail bed

Not every thick or discoloured nail is fungal.

Injury, psoriasis, ageing and other nail conditions can look similar.

Treatment can take months because toenails grow slowly.

Even after the infection is controlled, the damaged part of the nail needs time to grow out.

Athlete’s Foot

Athlete’s foot is a fungal infection of the skin.

It commonly affects the areas between the toes but can spread across the soles.

Symptoms may include:

• itching
• peeling
• redness
• cracking
• burning
• flaky skin

Warm, moist footwear can create an environment where fungal infection grows more easily.

Keeping the feet dry and changing damp socks can help reduce recurrence.

Plantar Warts

Plantar warts are caused by human papillomavirus and develop on the soles of the feet.

Because body weight pushes them inward, they may look flatter than warts elsewhere on the body.

They can sometimes be confused with corns.

A wart may interrupt the normal lines of the skin and can contain tiny dark dots from small blood vessels.

Some disappear without treatment, while others persist or become painful.

Flat Feet

Flat feet describe a low or absent arch when standing.

Many people with flat feet have no pain and need no treatment.

Problems are more likely when flat feet are associated with:

• foot fatigue
• arch pain
• ankle pain
• difficulty walking
• tendon problems
• changes that are getting worse

The shape of the arch alone does not determine whether a foot is healthy.

Function and symptoms matter more.

High Arches

High-arched feet place pressure differently through the foot.

Some people with high arches experience:

• pain under the heel or ball of the foot
• ankle instability
• repeated sprains
• calluses
• difficulty finding comfortable shoes

A high arch is not automatically a problem.

Treatment is usually considered when it causes symptoms or affects movement.

Foot and Ankle Arthritis

Arthritis can affect several joints in the foot and ankle.

Symptoms may include:

• pain
• stiffness
• swelling
• reduced movement
• difficulty walking
• changes in the shape of the foot

Osteoarthritis can develop after years of joint use or following an old injury.

Inflammatory conditions such as rheumatoid arthritis can also affect the feet.

Treatment depends on which joint is involved and how much function has been affected.

Big Toe Joint Pain

Pain at the base of the big toe can make walking difficult because this joint bends as the body moves forward.

Possible causes include:

• arthritis
• bunions
• gout
• injury
• joint stiffness

A stiff big toe can change the way someone walks and may shift pressure to other parts of the foot.

Gout in the Foot

Gout is caused by a build-up of uric acid crystals in a joint.

The big toe is a common site.

A gout attack can cause:

• sudden severe pain
• swelling
• redness
• warmth
• extreme tenderness

The pain can begin very quickly, sometimes overnight.

Repeated gout attacks can eventually damage joints if the underlying uric acid problem is not controlled.

Forefoot Pain

Pain under the ball of the foot is sometimes called metatarsalgia.

It is a description rather than one specific diagnosis.

Possible causes include:

• increased pressure
• footwear
• joint irritation
• nerve problems
• stress injuries
• changes in toe position

The exact location of the pain and when it occurs can help identify the cause.

Morton’s Neuroma

Morton’s neuroma involves irritation around a nerve between the toes, most commonly between the third and fourth toes.

Symptoms may include:

• burning pain
• tingling
• numbness
• the feeling of a pebble inside the shoe

Tight or narrow footwear can make symptoms worse.

Changing footwear and reducing pressure may help in milder cases.

Stress Fractures

A stress fracture is a small crack in a bone caused by repeated loading rather than one major injury.

The bones of the foot are common sites.

Pain usually becomes worse with activity and improves with rest.

Swelling may also occur.

Stress fractures are more likely after a sudden increase in running, walking or training.

Continuing to load the injured bone can delay healing.

Ankle Sprains

An ankle sprain occurs when ligaments are stretched or torn.

It often happens when the foot rolls unexpectedly.

Symptoms can include:

• pain
• swelling
• bruising
• difficulty putting weight on the foot

Many ankle sprains recover well, but repeated sprains can lead to ongoing instability.

Rehabilitation that restores strength and balance can be important after the early pain settles.

Foot Pain After Exercise

Pain after exercise can come from many sources.

A useful starting point is to ask:

• Where exactly is the pain?
• Did activity increase recently?
• Has footwear changed?
• Is there swelling?
• Does the pain occur during exercise or afterwards?
• Is it getting worse from week to week?

A sudden increase in training is one of the most common reasons for overuse injuries.

The body needs time to adapt to increased distance, speed or intensity.

Running and Foot Health

Running places repeated load through the feet and lower legs.

That does not make running bad for the feet.

Most problems occur when training load rises faster than the body can adapt.

Useful factors to consider include:

• weekly distance
• running surface
• recovery
• footwear
• previous injury
• strength
• sudden changes in pace or hills

Changing several of these at once can make it harder to work out what triggered the problem.

Footwear

Shoes affect comfort, pressure and stability.

A good fit usually provides enough room around the toes and holds the heel securely without excessive pressure.

Shoes that are too tight can contribute to:

• blisters
• corns
• nail problems
• bunion pain
• forefoot pain

Shoes that are too loose can allow the foot to slide and create friction.

The best shoe depends on the activity and the shape of the individual foot.

Shoe Size Can Change

Foot size can change over time.

Pregnancy, ageing, weight changes and changes in the arches can all alter foot length or width.

Continuing to buy the same shoe size for many years does not guarantee that the fit is still right.

There can also be size differences between brands.

Comfort and actual fit matter more than the number on the box.

Orthotics

Orthotics are inserts placed inside shoes to change pressure or support the way the foot functions.

They may be used for:

• heel pain
• arch pain
• some tendon problems
• pressure relief
• certain walking problems

Not everyone with foot pain needs orthotics.

Some problems respond better to strengthening, changes in activity or better footwear.

An orthotic works best when it addresses a specific problem rather than being used simply because the foot looks flat.

Custom and Off-the-Shelf Orthotics

Some orthotics are made specifically for the individual.

Others are ready-made.

A custom device is not automatically necessary for every person.

A well-chosen prefabricated insert may work well for many common problems.

More complex foot shapes or pressure problems may require something made more specifically.

Foot Strength

Feet contain many small muscles that help with balance and movement.

Strength can decrease after injury, long periods of inactivity or years of relying on very rigid footwear.

Exercises may focus on:

• calf strength
• toe control
• balance
• arch control
• ankle stability

Foot strengthening is usually most useful when it is matched to the actual problem.

Calf Flexibility

Tightness in the calf can limit ankle movement.

This may increase pressure through the heel or forefoot during walking.

Stretching can help some people, particularly when limited ankle movement is part of the problem.

Stretching alone will not solve every foot condition, so the reason for the restriction still matters.

Diabetes and Foot Health

Diabetes can affect the feet in several ways.

Over time, high blood glucose can contribute to:

• nerve damage
• reduced sensation
• poorer circulation
• slower wound healing
• increased risk of infection

A person may develop a blister, cut or pressure sore without feeling much pain.

This makes regular foot checks particularly important.

Diabetic Neuropathy

Diabetic neuropathy can reduce feeling in the feet.

Symptoms may include:

• numbness
• tingling
• burning
• unusual sensitivity
• reduced ability to feel temperature or injury

Loss of sensation can make small injuries more dangerous because they may go unnoticed.

Checking inside shoes for stones or rough areas can be useful when sensation is reduced.

Diabetic Foot Ulcers

A foot ulcer is an open wound that does not heal normally.

People with diabetes may be more vulnerable because of reduced sensation, pressure and circulation problems.

Ulcers can develop under areas that carry high pressure.

Early signs may include:

• broken skin
• redness
• swelling
• discharge
• an area that looks different from surrounding skin

Early attention matters because infection can spread quickly in a high-risk foot.

Circulation and the Feet

Poor circulation can affect healing and skin health.

Possible signs include:

• feet that feel unusually cold
• colour changes
• slow-healing wounds
• pain in the calves while walking
• reduced hair growth on the lower legs
• weak pulses

Circulation problems are more common in people with smoking history, diabetes, cardiovascular disease and increasing age.

Foot symptoms can sometimes be one of the first signs that circulation needs closer attention.

Numbness and Tingling

Numbness in the feet has several possible causes.

These include:

• diabetes
• nerve compression
• vitamin deficiencies
• spinal problems
• some medicines
• neurological conditions

Persistent numbness is important because reduced sensation increases the chance of unnoticed injury.

Swollen Feet and Ankles

Swelling can have many causes.

Possible reasons include:

• long periods standing
• injury
• venous problems
• medication
• pregnancy
• heart, kidney or liver conditions
• infection

Swelling in both ankles has different common causes from sudden swelling in one foot or leg.

The pattern and timing matter.

Children’s Foot Health

Children’s feet change as they grow.

Flat-looking feet, flexible arches and different walking patterns can be normal at certain ages.

Things that may deserve closer attention include:

• persistent pain
• frequent tripping
• walking that becomes more difficult
• one foot looking very different from the other
• repeated ankle injuries
• problems keeping up with other children

Growth itself can change movement, so children’s feet should not simply be judged against adult foot shape.

Growing Pains and Foot Pain

Not every pain in a growing child is caused by growth.

Heel pain can occur during periods of rapid development, especially in active children.

The heel growth plate can become irritated by repeated running and jumping.

Activity level, footwear and tight calf muscles can all contribute.

Older Adults and Foot Health

Feet change with age.

The natural fat padding under the foot can become thinner, joints may become stiffer and nails often become thicker.

Older adults may also have more difficulty reaching their feet.

This can make routine problems such as nail care, corns and dry skin harder to manage.

Keeping the feet comfortable supports mobility and independence.

Dry and Cracked Heels

Dry skin around the heels can become thick and split.

Cracks may become painful and, in deeper cases, bleed.

Regular moisturising can help soften the skin.

Pressure, open-backed shoes and spending long periods barefoot can make cracking worse.

People with diabetes or poor circulation need to be particularly careful with broken skin on the feet.

Blisters

Blisters usually develop through repeated friction.

Common causes include:

• new shoes
• long walks
• running
• wet socks
• poorly fitting footwear

Preventing repeated friction is often more important than simply covering the blister after it forms.

Shoes and socks should be adjusted when the same area repeatedly becomes sore.

Foot Odour

Foot odour is often caused by sweat interacting with bacteria on the skin.

Helpful steps can include:

• washing and drying feet well
• changing socks regularly
• allowing shoes to dry fully
• rotating footwear
• managing fungal infection where present

Persistent odour with itching or peeling may suggest a skin problem rather than sweating alone.

Toenail Changes

Toenails can change colour, thickness and shape for many reasons.

Possible causes include:

• fungal infection
• repeated trauma
• tight shoes
• psoriasis
• ageing
• previous injury

A dark mark under a nail is often due to trauma, but unexplained pigmentation that persists or changes deserves attention.

Nail Trauma

Running, hiking and tight footwear can repeatedly push the toes against the front of a shoe.

This may cause:

• bruised nails
• lifting nails
• thickening
• nail loss

The new nail can take many months to grow.

Reducing repeated pressure helps prevent the same problem from returning.

Skin Changes on the Feet

Changes in foot skin should not always be assumed to be fungal.

Redness, scaling or itching can also be caused by:

• eczema
• psoriasis
• contact irritation
• bacterial infection
• excessive dryness

The treatment depends on the cause.

Using antifungal products repeatedly without confirming the problem may delay the right treatment.

Balance and Falls

The feet play an important role in balance.

Pain, reduced sensation, weak ankle muscles and poor-fitting footwear can all increase the chance of falling.

Balance can also be affected by vision, medicines, inner-ear problems and general strength.

For older adults, keeping the feet comfortable and footwear secure can be one part of reducing falls risk.

Foot Pain Can Affect the Knees and Hips

Pain changes the way people move.

Someone avoiding pressure on one foot may begin limping or shifting weight.

Over time, this can place extra load on the ankle, knee or hip.

Treating the original foot problem can sometimes improve discomfort elsewhere simply by allowing a more normal walking pattern.

Weight and Foot Pressure

Body weight affects the amount of force passing through the feet.

Higher loads can make some foot problems more noticeable, including:

• heel pain
• forefoot pain
• arthritis
• tendon problems

Weight is only one factor.

Foot structure, activity, strength, footwear and previous injury can all matter too.

Standing for Long Periods

Jobs that involve standing for most of the day can place considerable load on the feet.

People may develop:

• heel pain
• tired arches
• swelling
• calluses
• forefoot discomfort

Supportive footwear, movement breaks and changing position can make long periods of standing easier.

When Rest Helps — and When It Does Not

Short-term rest can be useful after injury or when activity is clearly making a problem worse.

Complete rest for long periods is not always helpful.

Tendons, muscles and bones often need gradual loading to regain strength.

The goal is usually to reduce enough load for recovery while maintaining as much useful movement as possible.

Returning to Activity

Returning too quickly after foot or ankle pain can restart the problem.

A gradual return may involve increasing:

• walking distance
• running distance
• speed
• hills
• sport-specific activity

Changing one factor at a time makes it easier to see how the foot is responding.

Pain that steadily increases as activity rises may be a sign that progression is too fast.

Looking After Feet at Home

Simple foot care can prevent many everyday problems.

Useful habits include:

• washing and drying feet carefully
• moisturising dry skin
• checking shoes for wear
• wearing socks that fit properly
• trimming nails carefully
• changing damp footwear
• paying attention to persistent pain
• checking the feet regularly when sensation is reduced

Foot care does not need to be complicated to be useful.

Changes That Deserve Attention

Foot problems are worth taking more seriously when there is:

• persistent or increasing pain
• inability to put weight through the foot
• sudden swelling
• redness spreading through the foot
• an open wound
• a wound that is not healing
• loss of sensation
• colour changes
• significant warmth
• pus or discharge
• sudden change in foot shape
• repeated ankle instability

People with diabetes, poor circulation or reduced sensation may need to respond earlier because small problems can become more serious.

A Practical Approach to Foot Health

Healthy feet are not necessarily perfectly shaped feet.

Many people have flat arches, bunions, unusual toes or other structural differences without significant problems.

What matters is whether the feet are comfortable, the skin and nails are healthy and movement is not being limited.

When pain develops, the most useful question is often not simply where it hurts, but why that area is being overloaded.

Footwear, activity, strength, joint movement, medical conditions and the way someone walks can all contribute.

Good foot care is about keeping people moving comfortably for as long as possible. Paying attention to persistent pain, skin changes, circulation and sensation can prevent small problems from becoming much harder to manage later.
