When you think about foot mobility and mechanics, the big toe might not be the first thing that comes to mind. However, big toe extension plays a big role in our daily activities. Big toe extension is essential for walking efficiency, running performance, and maintaining balance. Improving big toe mobility can also aid in preventing common foot issues, such as plantar fasciitis and bunions. It is also a key component in arch support and ankle stability. This article will review the role of the big toe, the benefits of big toe extension, and how to improve your big toe mobility to support your foot health and posture.

Anatomy of the Big Toe
The main joint of the big toe is the metatarsophalangeal (MTP) joint. This is the joint where the big toe flexes and extends. It is important for gait mechanics and walking efficiency. The muscles responsible for the flexing and extending are the flexor hallucis longus and the extensor hallucis longus. If either the joint or the muscles are stiff, it will limit your ability to move your big toe.
Believe it or not, but the big toe is also extremely important for supporting the rest of your foot and ankle. Even though it has it’s own joint, this joint also affects many other things around it. Hence why having poor big toe extension is associated with many other foot and ankle issues, like plantar fasciitis, shin splints, and bunions or bunionettes.
This windlass mechanism plays a critical role in the biomechanics of walking and running. Understanding the anatomy of the big toe is the first step towards understanding how important it is and how you can actually improve your walking, running, and overall foot health.
The Role of the Big Toe in Gait and Posture
When walking, a phenomenon known as the “windlass mechanism” takes effect. When you push off your big toe and it moves into extension, the windlass mechanism creates more height within the arch of your foot. This mechanism helps explain how the plantar fascia supports your foot during weightbearing activities. Weightbearing also involves static standing, not just walking and running. With a faulty windlass mechanism due to poor big toe extension, it still shows that the plantar fascia does not provide sufficient support to the foot in standing. You may also see the arch collapse and foot pronation in standing.
If the big toe is lacking extension during push-off (toes extending and getting ready to push off the ground), the arch of the foot will not increase as it should. The arch can collapse and may even result in the foot pronating excessively. When running, the big toe also aids in shock absorption. without this toe extending, there is less shock absorption. The rest of the foot or further up your leg will absorb more of the impact, which can create problems in the future and increase your chance of injury. Surprisingly, I have seen runners with hip pain that is actually coming from a lack of mobility within the foot. This included both a lack of ankle dorsiflexion and big toe extension.
Benefits of Improved Big Toe Extension
Being able to extend your toe while sitting and without your toe on the ground is one thing. Seeing proper big toe extension during walking is another thing. When you are putting weight on your feet, the mechanisms of how the foot works change a bit. You have to make sure you are working on your big toe extension with weight going through your legs. The big toe needs to be able to support the weight of your body. The only way to ensure this is to work on standing exercises. And why, exactly, should you be doing this? Here are some reasons why emphasizing big toe extension will be beneficial for you:
- Improves Balance and Stability: The big toe provides arch support and is a main contributor to balance both statically and dynamically.
- Promotes Healthy Gait Mechanics: Proper big toe extension is crucial for the biomechanics of walking. It also supports 40-50% of the body’s weight when walking. If this joint is not functioning properly, walking becomes much more challenging.
- Reduces Risk of Foot-Related Conditions: By improving toe mobility and intrinsic foot strength, you minimize the chances of developing painful conditions like plantar fasciitis.
- Enhances Athletic Performance: Athletes can notice a significant difference in their performance as improved toe extension contributes to stronger pushes off the ground, better shock absorption, and reduces risk of injury.
Factors Influencing a Stiff Big Toe
Lifestyle factors are a main contributor to a stiff big toe. A sedentary lifestyle is one of the most common contributors. If you aren’t moving, your foot or toe isn’t moving either. On top of that, poor footwear choices can exacerbate this issue. Small toe boxes that don’t allow your toe to move adequately will limit your ability to push off your big toe when walking. Remember, this is a requirement for normal gait mechanics. And while the big toe can affect other parts of your foot, the same is true in regards to the rest of your foot. If your intrinsic foot muscles are weak and you have poor arch support, this will negatively impact your big toe. Everything needs to work together.
Now, genetic predispositions cannot be forgotten. Hallux valgus, or the formation of a bunion, has been found to have an inheritable genetic component. A clubfoot may also influence the positioning of the big toe and how it functions. While genetics don’t explain everything, they do have to be considered when treating the root cause of foot or ankle pain. It does not mean that certain things cannot be treated, but it does mean that there could be possible limitations with recovery and/or change the overall treatment plan.
Assessing Your Big Toe Mobility
To assess your big toe mobility, start by sitting and simply lifting your big toe up using your fingers. This is the easiest way to check, but notice that we are not in a weightbearing position. We are purposefully doing this because it will still give us useful information. You want around 60 degrees of big toe extension. Now you don’t need to pull out a protractor or goniometer for this; just eye it. Remember to do both sides. Does one significantly differ from the other? Are both really stiff or do both move pretty well? Let’s move on to the next assessment, which involves standing.
The next assessment will now look at your big toe extension in weightbearing. Remember your results from earlier as this can give you clues as to what you need to work on in the future. In standing, can you lift your big toe to about the same height that you were able to lift it in sitting? Another thing to look at is if you can even lift your big toe without raising any of your other toes. This can actually be quite challenging for a lot of people (me included!). Again, you want about 60 degrees of range of motion.
To interpret your results:
First, you want to assess if you were even able to reach around 60 degrees lifting your toe with your fingers. If you can’t, this indicates that there may be some joint restriction at the MTP joint. If you were able to lift your toe to an adequate height in sitting, but struggled in standing, there may be a few different issues. You may have some stiffness within the flexor hallucis longus muscle, limiting your ability to lift the toe into extension. There may be some weakness within the extensor hallucis longus muscle. There may also be a coordination issue. If you have a hard time lifting your big toe in isolation without moving any of the other toes, there is definitely a coordination issue. Regardless, learning where you limitations are shows you which areas you need to work on.
Exercises to Improve Big Toe Extension
Incorporating specific exercises into your daily routine can make a significant difference in your foot health. These exercises are designed not only to improve toe mobility, but also to promote foot posture, balance, and foot and ankle stability.
Self Big Toe Mobilization
Sit with one ankle crossed and resting on your knee. You will be working on this foot. One hand will be holding onto your big toe. The other hand will be massaging the bottom part of your foot.
Place your thumb just under the ball of your foot under where your first toe is. Hold steady pressure here. Then slowly push your big toe backwards into extension using your other hand. Maintain the pressure with your thumb into the bottom of your foot. You might feel a taut band under your thumb. This is the area you are massaging.
Alternate between extending your toe and relaxing it and complete this for 2-3 minutes. Repeat on the other foot if necessary.
Alternating Seated Heel and Toe Raises
Sit with your feet flat on the ground.
Push up onto your toes by lifting your heels. Then lower your heels back to the ground and then lift your toes and the balls of your feet. Keep alternating between these two positions.
Perform 2-3 sets of 10-12 reps.
Weight Shift into Push Off
Stand in a split stance. You can hold onto something for balance for this exercise.
Rock your back foot from your heel down and lift it up until you shift your weight onto your toes. This pushes your great toe into extension. It should also look like your normal walking pattern just before you lift your foot off of the ground. Once you shift your weight onto your toes, rock your heel back down to the ground.
Keep repeating this rocking motion for 20-30 reps on one foot. Switch to the other foot if needed.
Double Limb Heel Raise
Make sure to perform this without shoes on so you can feel the ground underneath you. Push up onto your toes making sure to keep your weight shifted over the 1st and 2nd toes. You can hold onto something for balance if you need to.
Perform 30 repetitions.
Single Leg Balance
Stand on one leg with your foot on the ground. If this is challenging, you can start by holding onto something like a wall or chair.
You can challenge your balance by reducing your pressure into whatever you are holding. Try using your fingertips or intermittently letting go until you need to hold on again.
Balance for up to 30 seconds, repeating 3 times on each leg.
Incorporating Toe Mobility into Daily Routine
Working on toe mobility throughout your day is actually easier than you think. There are many times throughout your day that you can work some of these exercises into things you are already doing. This makes it easier as you don’t feel like you have to carve out extra time during your day.
You can do some standing heel raises as you wait for your coffee to brew, while food is in the microwave, or when washing your hands at the sink. While sitting and watching tv, you can perform your alternating heel and toe raises or work on stretching and mobilizing your big toe.
If you’re standing in line at the grocery store, you can place your toes on the ground on one of your feet and stretch your big to into extension or work on single leg balance. Paying attention to how you are walking is also helpful. Make sure your toes are pointing forward, allowing your foot to rock up and get to position to allow for your big toe to extend. Many times, the big toe gets stiff due to poor walking mechanics. Allowing the leg to rotate outward prevents the toe from moving into extension. Focusing on keeping those toes aimed forward will make it easier for that big toe to bend backwards as intended.
Preventing Future Issues
The role of the big toe in walking efficiency, balance enhancement, and posture correction cannot be overstated. To prevent future issues and maintain the mobility and strength of your big toe, consider adopting several key habits and practices.
- Choose the Right Footwear: Investing in shoes with proper arch support and a toe box that fits the width that you need. Shoes that are too tight or lack adequate support can lead to foot pronation and strain on your big toe, hindering its natural movement and weakening your foot’s inherent structure.
- Regular Toe Mobility Exercises: Incorporating toe mobility exercises (like the ones above) into your daily routine can greatly improve your big toe extension. These exercises can help improve gait mechanics and reduce the risk of plantar fasciitis.
- Maintain Good Foot Hygiene and Care: This includes keeping your feet clean and dry to prevent infections that could limit your mobility. Regular check-ups with a healthcare provider specializing in foot health can also catch and address any potential issues early on. This is extremely important for individuals with diabetes and/or neuropathy.
- Practice Correct Walking and Running Mechanics: Poor form during physical activities can contribute to joint health problems and decrease your walking efficiency and running performance. Guidance from a physical therapist or a coach can ensure you’re moving correctly, thereby protecting your big toe and the rest of your foot (and body) from injury.
