Top 5 Running Injuries That Affect the Feet and Ankles (And What Manhattan Runners Need to Know)

If you've ever finished a run along the Hudson River Greenway or pushed through a loop in Central Park only to feel a sharp pain in your heel the next morning, you're not alone. Running is one of the most popular forms of exercise in Manhattan, but it's also one of the leading causes of foot and ankle injuries we see in the office.

The good news? Most running injuries are preventable, and almost all of them are treatable when caught early. The bad news? Too many runners ignore the warning signs until a small problem turns into something that sidelines them for months.

Here's a breakdown of the five most common running injuries that affect the feet and ankles, plus answers to the questions runners ask us (and Google) the most.

1. Plantar Fasciitis

This is hands down the most common running injury we treat. Plantar fasciitis is inflammation of the thick band of tissue that runs along the bottom of your foot, connecting your heel to your toes.

You'll usually feel it as a stabbing pain in the heel, especially with your first few steps in the morning or after sitting for a while. It often eases up once you start moving, which is why runners tend to brush it off. The problem is that running on it actually makes the underlying inflammation worse, even if it feels better mid-run.

Common causes include tight calves, worn-out shoes, sudden increases in mileage, and running on hard surfaces like the concrete sidewalks all over Manhattan.

2. Achilles Tendinitis

The Achilles tendon connects your calf muscles to your heel bone, and it takes a beating every time your foot pushes off the ground. When you ramp up your training too quickly or run a lot of hills (looking at you, runners who train on the Harlem Hills loop), the tendon can become irritated and inflamed.

Symptoms include stiffness in the back of the heel, especially in the morning, along with pain that worsens during or after a run. Some runners notice swelling or a lump along the tendon itself.

Ignoring Achilles tendinitis is one of the worst things you can do. A chronically inflamed tendon can eventually rupture, and that's a much bigger problem than a few weeks of rest and rehab.

3. Stress Fractures

A stress fracture is a tiny crack in the bone caused by repetitive impact. In runners, they show up most often in the metatarsals (the long bones in the middle of your foot) or in the heel bone.

Unlike a sudden break from a fall, stress fractures sneak up on you. The pain usually starts as a vague ache during runs, then gets sharper and more localized. You might notice swelling or tenderness when you press on a specific spot.

If you suspect a stress fracture, stop running. Continuing to train on a stress fracture can turn a small crack into a complete break, which could mean surgery and a much longer recovery. We typically diagnose these with imaging, since they don't always show up on a basic X-ray right away.

4. Ankle Sprains

Manhattan is a minefield of cracked sidewalks, uneven curbs, and potholes you can't see until you've already stepped in one. It only takes one bad step to roll your ankle, and depending on the severity, you might be dealing with anything from mild ligament stretching to a full tear.

Most sprains involve the outside of the ankle, where the ligaments are more vulnerable. You'll feel immediate pain, often followed by swelling and bruising. Walking might be uncomfortable or impossible.

A lot of runners try to walk off an ankle sprain and get back to training too soon. This is a mistake. Ligaments need time to heal properly, and rushing the process leads to chronic ankle instability, which means you're more likely to sprain it again and again.

5. Shin Splints

Technically called medial tibial stress syndrome, shin splints cause aching pain along the inside of the shin bone. They're most common in newer runners or those who've recently increased their mileage, switched to harder surfaces, or started wearing different shoes.

The pain usually starts as a dull throb that goes away once you warm up, but over time it can become more persistent and intense. If left untreated, shin splints can progress into a stress fracture in the tibia.

Now let's get into the questions runners ask all the time.

How Do I Know If My Running Injury Is Serious?

A few red flags tell us an injury needs immediate attention. If you can't put weight on the foot, if there's significant swelling or bruising, if the pain is sharp and localized to one spot, or if symptoms don't improve after a few days of rest, it's time to come in.

General soreness after a hard run is normal. Pain that changes the way you walk or run is not.

Can I Run Through the Pain?

Almost always, the answer is no. Running through pain is how minor issues become major ones. Pain is your body's way of telling you something is wrong, and ignoring it doesn't make it go away. It just gives the problem more time to get worse.

There's a difference between discomfort (tired legs, mild soreness) and pain (sharp, persistent, localized). If you're not sure which one you're dealing with, that's a good reason to get it checked out.

How Long Does It Take to Recover From a Running Injury?

It depends entirely on the injury and how soon you address it. Mild plantar fasciitis or shin splints might resolve in a few weeks with proper care. A stress fracture typically takes six to eight weeks of no running. A bad ankle sprain can take anywhere from two weeks to several months depending on severity.

The biggest factor in recovery time is how quickly you start treatment. Runners who come in at the first sign of trouble almost always heal faster than those who wait.

What Shoes Should I Be Running In?

There's no single best shoe for every runner. The right shoe depends on your foot structure, your gait, your weekly mileage, and the surfaces you run on. What works for your training partner might be completely wrong for you.

That said, the most important rule is to replace your shoes regularly. Most running shoes lose their cushioning between 300 and 500 miles. If you've been running in the same pair for a year and you're logging consistent mileage, they're probably part of the problem.

If you're dealing with recurring injuries, a gait analysis can identify issues with your stride or foot mechanics that the right shoe (or custom orthotic) can help correct.

How Can I Prevent Running Injuries?

A few habits go a long way. Increase your weekly mileage gradually, no more than about 10 percent per week. Don't skip strength training, especially for your hips, glutes, and core, since weakness in these areas often shows up as foot or ankle pain. Stretch your calves and hips regularly. Replace your shoes on schedule. And listen to your body when it's telling you to back off.

Cross-training with low-impact activities like swimming or cycling also gives your feet and ankles a break from the constant pounding.

When Should I See a Podiatrist?

If you've tried rest, ice, and over-the-counter anti-inflammatories for a week or two and the pain isn't getting better, come in. The same goes for any injury that's affecting how you walk or run, any pain that's getting worse instead of better, or any injury that keeps coming back even after you think it's healed.

Running is supposed to make you feel good. If it's hurting you, something needs to change, and we can help figure out what.

Whether you're training for the New York City Marathon or just trying to keep your weekly Central Park loop in your routine, your feet and ankles deserve attention. Don't wait for a small ache to become something that takes you out of the game for months.

If you're dealing with any of these injuries, or if you just want a checkup before your next training cycle, schedule an appointment. The sooner we catch something, the sooner you're back on the road.
