Top 7 Sports and Running Injuries to Watch for in Your Feet and Ankles
(And What a Podiatrist Can Do)
The run felt fine while you were moving. Then the heel tightened during the walk back to the car, or the ankle started to ache once the game was over. Sometimes one spot on the foot becomes painful enough that you begin changing the way you walk without even thinking about it.
Athletes expect a certain amount of soreness, but pain becomes more concerning when it returns in the same place, changes running form, creates swelling, or gets worse from one workout to the next. Sports and running injuries can happen during one bad landing, though many develop over time as the feet and ankles absorb more stress than they have time to recover from.
For runners, school athletes, and weekend competitors in Ann Arbor, the question is usually the same: can this be trained through, or does it need attention? A podiatrist can help identify which structure is causing the pain, rule out injuries that need protection, and build a treatment plan that supports healing without losing sight of the athlete’s return to activity.
Why Running Injuries Build
There are two broad categories for injuries: Immediate and gradual. Immediate injuries happen all at once: you roll an ankle, land badly, or feel something pull during a sprint, and the cause is obvious.
Overuse injuries tend to develop more gradually. The body keeps taking on more work than it has time to recover from, and the first sign may be a small ache that only appears after a run. As the irritation builds, the pain may start earlier in the workout or continue into normal walking.
A change in mileage, more hill work, harder surfaces, or worn running shoes can all raise the strain on the feet and ankles. Tight calf muscles and fatigue can change the way you move as well. Once that happens, the body starts compensating. A sore heel may make you shorten your stride. An unstable ankle may push more work onto the other side.
Those adjustments can place added stress on the shin, knee, or hip. The original problem may be in the foot or ankle, but the effects can spread once the body starts moving around, causing pain.
1. Plantar Fasciitis: The First-Step Heel Pain
The plantar fascia is a thick band of tissue that runs along the bottom of the foot from the heel bone toward the toes. When it becomes irritated, the pain is usually at its strongest near the inside of the heel.
A common clue is pain with the first few steps in the morning or after sitting for a while. The discomfort may ease once the foot warms up, then return after a run or at the end of a long day. For runners, plantar fasciitis can develop after a sudden increase in training, a change in shoes, or repeated impact when the calf and ankle are tight. Foot shape and pressure patterns can play a role, too.
Early treatment usually starts with reducing the activity that keeps aggravating the area. Calf stretching, supportive running shoes, ice packs, and a short break from higher-impact training may help. Physical therapy or custom orthotics may be useful when the problem is tied to flexibility, strength, or the way pressure moves through the foot.
Heel pain should be checked when it starts changing your stride, becomes severe, or stays present despite rest and stretching.
2. Achilles Tendinopathy: When Warm-Up Stops Helping
The Achilles tendon is the large tendon that connects the calf muscles to the heel bone. It works every time you walk, run, climb, or push off the ground.
Achilles tendinopathy (sometimes called Achilles tendonitis or Achilles tendinitis) often starts as stiffness behind the ankle. The tendon may feel sore at the beginning of a run, loosen up as you warm up, then ache again afterward or the next morning.
That pattern can be misleading because the temporary improvement makes it seem safe to keep going. In reality, the tendon may be struggling to keep up with the current training load.
Hill work, sprinting, rapid mileage increases, and limited calf strength can all add stress to the Achilles tendon. Treatment usually involves changing the running routine for a period of time, then rebuilding strength through a structured loading plan. Physical therapy and footwear adjustments may also help.
A sudden pop, marked bruising, or a clear loss of push-off strength needs prompt evaluation. Those symptoms can point to a partial or complete rupture.
3. Ankle Sprains: The Injury That Keeps Returning
An ankle sprain can happen during a trail run, a quick change of direction, or a bad landing. The pain usually sits along the outside of the ankle, where the ligaments are most likely to stretch or tear.
Swelling and bruising may appear quickly, though the amount of swelling does not always tell you how serious the injury is. A mild sprain and a more significant ligament injury can look similar in the first few hours.
Rest, ice, compression, and elevation can help control pain and reduce swelling after a recent sprain. Those steps are useful early on, but they do not replace an exam when the ankle is very painful or unstable.
You should seek care when you cannot bear weight, when the swelling is severe, or when the pain feels concentrated over a bone. Numbness, deformity, or repeated giving way are also reasons to have the ankle checked.
An ankle that keeps rolling after the original injury may not have regained full strength and balance. That can raise the risk of further injury, especially during sports that involve cutting, jumping, or uneven ground.
4. Stress Fractures: Small Cracks, Precise Pain
Stress fractures are small cracks or areas of significant bone stress caused by repeated impact. They commonly affect runners in the shin bone and the bones of the feet.
The pain usually stays in one specific spot. At first, you may only feel it near the end of a run. As the injury progresses, it may start earlier, continue during walking, or remain present when you are resting.
A sudden increase in mileage, inadequate recovery, hard surfaces, and a quick return to impact after time away can all contribute. Bone health, nutrition, and low energy availability also matter.
This is one injury that should not be trained through. Continuing to run can make the crack worse and extend the recovery period.
An X-ray may not show a stress fracture early on, so persistent localized pain may require more advanced imaging. Pain that affects walking or remains present at rest should be evaluated.
5. Shin Splints: Broad Ache or Bone Warning?
Shin splints, also called medial tibial stress syndrome, cause pain along the inner edge of the shin bone. The discomfort usually covers a wider area than the focused pain of a stress fracture.
Many runners first notice shin splints after increasing distance too fast or adding more hills. Tight calf muscles, weak lower-leg muscles, and a change in running shoes can also add strain. The pain may show up at the start of a run, ease for a while, then return afterward. As the irritation worsens, it can become more persistent.
Treatment usually begins with a break from painful impact, along with ice, calf stretching, strength work, and cross-training. A bike, pool, or other lower-impact activity can help maintain fitness while the shin settles.
The location of the pain matters. A broad ache fits shin splints more closely. A small, sharply painful spot may be a stress fracture and should be checked.
6. Peroneal Tendon Injuries: Pain Along the Outside Edge
The peroneal tendons travel behind the outer ankle bone and help control the foot during push-off and movement across uneven ground.
Pain from these tendons may appear behind the outside of the ankle or along the outer edge of the foot. Some athletes notice weakness, snapping, or discomfort that becomes worse on trails and sloped surfaces. These injuries can develop after repeated ankle sprains or continued training on an ankle that never regained full stability. High arches and unstable footwear can add to the strain.
The first step is usually to reduce the activity that keeps aggravating the tendon. Bracing, physical therapy, strength work, or temporary immobilization may be needed, depending on the severity of the injury.
Pain during normal walking, persistent swelling, or a snapping sensation deserves an exam.
7. Turf Toe and Forefoot Overload: Pain at Push-Off
Turf toe is a sprain of the big toe joint caused by excessive bending. It often happens when the forefoot stays planted and the body moves forward over the toe during a sprint or sudden push-off.
Football players, soccer players, and other athletes who rely on quick acceleration are especially vulnerable. Flexible shoes and artificial turf can increase the strain at the joint. The pain may sit under or around the big toe and become more noticeable when running or jumping. Swelling, bruising, and weakness during push-off can make the entire stride feel different.
Other forefoot injuries can create pain beneath the ball of the foot without a clear toe sprain. Tight cleats, repetitive loading, and long periods of running can all contribute.
Reducing painful push-off is important. Shoes that limit bending at the big toe may help in some cases. Marked swelling, bruising, or loss of strength should be evaluated.
Is It Soreness or an Injury?
Post-workout soreness usually affects a broader muscle area and improves with rest. It should not change the way you walk or run, and it tends to fade within a short period.
An overuse injury behaves differently. The pain returns in the same place, begins earlier during each workout, or lingers after activity. You may also notice that you are changing your stride or avoiding pressure on the injured area.
Some signs call for prompt care. These include an inability to bear weight, a sudden pop, severe swelling, visible deformity, numbness, a change in skin color, or loss of strength. Localized pain over a bone should also be taken seriously.
What Should You Do First?
For a recent foot or ankle injury, stop the activity that caused the pain and give the area time to settle. Ice can help with pain and swelling when used with a cloth barrier between the skin and the ice pack.
Compression may help control swelling and support the injured area. It should not cause tingling, numbness, or a color change in the foot. Elevating the foot or ankle can also help reduce swelling during the first stage of recovery.
Over-the-counter anti-inflammatory medicine may help some people manage pain, though it is not a good choice for everyone. A healthcare provider can give guidance based on your medical history and the injury itself.
Home care has limits. A suspected fracture, tendon rupture, severe sprain, or injury that prevents normal walking should be evaluated.
Can You Keep Running?
You should stop or reduce training when pain changes your stride, becomes worse during the run, or causes swelling afterward. Pain that returns sooner with each workout is another sign that the tissue is not recovering well.
A single, precise spot over a bone deserves extra caution because that pattern can point to a stress fracture.
The goal isn’t to see how much pain you can tolerate. Continuing to load an injury may delay healing and create more strain elsewhere in the body.
Before returning to a normal running routine, you should be able to walk without limping, use stairs without sharp pain, and complete daily activities without increased swelling. You should also be able to balance on the injured side and perform basic strength work without losing control.
A return to running usually starts with short, easy intervals before distance, hills, or speed are added back in.
Prevention Is About Managing Change
There's no shoe, warm-up, or exercise plan that can prevent every injury. Good training decisions can still reduce avoidable stress.
Mileage should rise in measured steps. Adding distance, hills, and speed at the same time makes it harder for the body to adapt. Cross-training can help by reducing repetitive impact while keeping the cardiovascular system active.
Strength work matters too. The calves, feet, ankles, hips, and other supporting muscle groups all help control the way the body handles each step.
The familiar 10% rule suggests limiting weekly mileage increases to about 10%, but that number is only a rough guide. Training history, sleep, terrain, prior injuries, and workout intensity all affect how much change the body can handle.
Running shoes should be replaced when the cushioning feels compressed, the tread has worn down, or the shoe is no longer supporting the foot well. The common 300-to-500-mile range can be useful, but visible wear and new discomfort may tell you more than the mileage alone.
What a Podiatrist Can Add
Foot and ankle injuries can feel similar even when different structures are involved. Heel pain may come from the plantar fascia, the Achilles tendon, or the heel bone. Pain after an ankle injury may involve a ligament, a tendon, the joint, or a fracture.
A podiatrist can examine the exact location of the pain, ankle motion, calf flexibility, strength, balance, and pressure through the feet. Shoe wear and recent changes in training can also provide useful clues.
An X-ray may be needed when a bone injury is suspected. Further imaging can help when the concern involves a stress fracture or tendon tear.
Treatment may include activity changes, physical therapy, bracing, a medical boot, footwear guidance, custom orthotics, or more advanced treatment in severe cases. The right plan depends on the injury and the athlete rather than a standard timeline.
Pain Is Training Information
Athletes get used to discomfort, which can make it hard to know when the body is asking for a real change.
The pattern matters more than toughness. Pain that stays in one place, creates swelling, changes movement, or becomes worse across several workouts is giving useful information about how the body is handling the load.
A few adjusted training days can be frustrating. A long recovery from a stress fracture, unstable ankle, or Achilles injury is harder.
