Weak Ankles Running? Stabilization and Strengthening for Pain Free Running

Do you suffer from frequently spraining your ankles? Do you have a sensation like you have weak ankles running? If you’ve ever strained to stabilize your ankles on a run or notice other types of knee or hip pain, weak ankles may be the silent factor holding you back. Ankle instability can snowball into compensation patterns, pain, and missed training sessions. The trick is if you want to strengthen and stabilize your ankles, you can’t just focus on the ankles. You have to work on strengthening other areas, too. This post will review why ankle stability is important for runners, how to determine if you are running with weak ankles, and go over what areas you should be focusing on to stabilize your ankles for pain-free running.

Why Ankle Stability Matters for Runners

When it comes to running and performance, most people think about lung capacity, leg strength, or even shoe choice. But the truth is, your ankles are the foundation for every step you take, quite literally. Weak ankles when running don’t just affect your feet. It disrupts your entire kinetic chain up your leg. This leads to compensations int he knees, hips, and low back.

Each time your foot hits the ground, your ankles absorbs and transfers force upwards. If it is unstable, those forces do not get absorbed or transferred efficiently. This creates inefficiencies in your running mechanics, energy transfer and conservation, and increases injury risk. If your ankles can’t keep up with the demand, it affects your whole stride, plus more.

The Mechanics of the Ankle

Weak ankles running usually stems from a mix of leg weakness somewhere along the kinetic chain, poor proprioception (your body’s ability to sense where you are in space), limited mobility, and underactive stabilizing muscles. Instability over time changes how your foot strikes the ground and how your leg absorbs impact. This means more strain on the joints and muscles, wasted energy with each step, and a higher chance of rolling an ankle and developing overuse injuries. The mechanics matter. Even small changes in these mechanics can throw the whole system off.

The main ankle joint, known as the talocrural joint, is what performs the actions dorsiflexion (pulling the toes towards your head) and plantarflexion (point the toes down like you are stepping on a gas pedal). Both have to have sufficient mobility to function optimally. Limited dorsiflexion is most commonly seen and affects running mechanics. It can lead to common injuries such as plantar fasciitis, Achilles strains or tears, shin splints, and knee pain.

Signs and Symptoms of Weak Ankles Running

Feeling the sensation of your ankles frequently wanting to roll of having frequent rolled ankle injuries can be a sign that you deal with chronic ankle instability. If you feel better with ankle braces or feel like you need constant support at your ankle may be another sign that you deal with weak ankles and instability. Uneven terrain can add to these sensations, but you may also feel it on even terrain, as well. Pain in the front or sides of the ankle, as well as knee pain, and sometimes hip pain, may also be signs that you should check your ankles for appropriate stability and strength.

What Can a Running Analysis Do for Me?

Getting a running analysis by a physical therapist could be very helpful in establishing exactly what your body needs in relation to your running mechanics. Watching how you run can give key insight as to what is really going on and can be a great way to zone in on what your body is missing while you are running and create a more efficient running stride.

Here are some things that may be helpful to watch out for as you are running:

Excessive foot pronation in single-limb stance
Poor shock absorption at impact
Poor push-off
Avoidance of 1st ray depression at push-off
Knee valgus
Hip drop in single-limb stance
Lacking hip extension in late stance phase
Inadequate dorsiflexion range for foot clearance and forward motion of the tibia
Inadequate reciprocal trunk rotation

While this is a non-exhaustive list, this can give you an idea as to what things to look for when running. Clearly, it looks like a lot and can be quite hard to decipher on your own and without trained eyes to assist you. However, taking a quick video of you running from the front, side, and back views for a couple of seconds and watching it back can be a great starting point. If you are looking to go more in depth, I recommend seeing a physical therapist for a running analysis.

What Should I Be Focusing on For Weak Ankles Running?

As discussed earlier, pain in the ankle while running can happen for many different reasons. So what areas should you be focusing on? The key here is to treat the root cause of the problem. If you consistently try to work on one thing and you aren’t seeing results (aka, your pain isn’t going away), then you are focusing on the wrong thing. This is where a running analysis can come in handy.

Based off of common patterns and the most common injuries I have seen when treating runners or individuals with ankle pain and instability, there are key areas that commonly show up. These are foundational elements you need not only for daily tasks, but also for running. Here are three key areas you can start focusing on to help with your ankle pain:

Tibialis Posterior

This muscle lies deep in the back part of the lower leg and its tendon runs around the inner ankle. This muscle is important because it provides support to the medial longitudinal arch of the foot.

Tibialis posterior dysfunction may lead to a collapsed arch (flat feet or a pronated food). This can then lead to many issues, one commonly being foot/ankle pain when walking and running.

It is important to make sure this muscle is strong and works appropriately to help stabilize the arch, especially when running as there are increased loads through the foot and ankle. If your arch is collapsing at impact while running or you notice your feet have flat arches, you may need to work on this muscle.

The Peroneals (Fibularis Longus and Brevis)

Fibularis longus and brevis (also known as the peroneals) make up the lateral compartment of the lower leg. The tendon of fibularis longus runs around the outer ankle and crosses the bottom of the foot. Because of where it crosses and inserts in the foot, this muscle maintains the transverse arch of the foot and depresses the head of the 1st metatarsal when you are in a weight-bearing position.

Together, tibialis posterior and fibularis longus work in tandem to help support the foot and ankle and provide stability when standing and moving. These muscles must work together for proper mechanics of the foot and ankle. If you notice your feet rotate our (your toes rotate outwards and your heels come inward) or you avoid pushing off of your big toe, your fibularis longus muscle is most likely weak. This needs to be strengthened for appropriate walking and running mechanics.

Gluteus Maximus and Medius

When you have weak ankles running, it is important to not only train the muscles of the foot, ankle, and calf, but to also incorporate the larger proximal muscle groups. Now why is this?

Muscle groups closer to the center of the body (proximal muscle groups) are larger, stronger, and provide stability to the rest of the limb. Even though we may be dealing with weak ankles and ankle pain, you cannot neglect areas up the kinetic chain. Whatever happens at the ankle can affect the knee and hip and vice versa.

Gluteus Maximus

Gluteus maximus is the largest muscle in the back of the hip (our bums). This muscle is responsible for three actions at the hip: hip extension, abduction, and external rotation. Because of the large size of the gluteus maximus, it is important to train this muscle to effectively help propel us as we run. This muscle will be used more in sprinting compared to endurance running as it helps control trunk flexion and increases in activation with rapid powerful hip extension.^[1] If interested, you can read more about gluteus maximus activity and function here.

Gluteus Medius

Gluteus medius is another glute muscle located on the lateral aspect of your hip. This muscle helps stabilize the hip every time the foot comes in contact with the ground. During running, the force traveling through our body increases by 3x our own body weight. That means the gluteus medius needs to be relatively strong to be able to stabilize the pelvis during running activities.^[2] If interested, you can read more about gluteus medius activity and function here. If you notice your hip drops when in single-limb stance, you will need to work on strengthening the gluteus medius muscle.

Integrating Stability & Balance Into Your Training Plan

We just reviewed lots of muscle groups that need to be strong. This is extremely important when running. But we also cannot forget to work on stability and balance exercises. Both of these also play important concept with both walking and running. ensuring you have a training plan that incorporates both strengthening and balance will be the most beneficial for helping you overcome your ankle pain with running.

Try This for Your Next Run

Try performing a gluteal activation warm-up before your next run.
In between runs, work on strengthening the peroneals and tibialis posterior to prevent arch collapse.
Incorporate balance exercises for pelvic stability which can later translate to improved stability and running mechanics.

When to Pull Back and Reassess

Even with a well-suited strengthening plan that is personalized to you, there are times your body may tell you to slow down. If you notice swelling that doesn’t go away after 48 hours, sharp pain during or after a run, or a repeated “giving way” sensation in your ankle, it’s time to take a break. Pushing through these warning signs can turn a manageable irritation into a lingering injury. When beginning to return to activity, start slow. Reduce mileage, swap in low-impact cross training, and prioritize mobility and stability work. Knowing when to pull back is a skill in itself. You can refer to this post here for a little more clarity and guidance on what pain is appropriate to push through or not.

Building ankle strength gives you the foundation your runs need to last. When you focus on building up weak ankles, everything changes. Your gait improves, confidence returns, and your body stays resilient. Remember… running starts from the ground up.
