7 Key Concepts
Kinetic Chain
The interconnected system of joints and segments in the body where movement at one joint affects others. Dr. Conley explains that foot issues can be a 'window' to problems elsewhere in the kinetic chain, such as the hips and pelvis.
Aberrant Loads
Abnormal or dysfunctional forces applied to the body. Dr. Conley notes that the foot is the only place in the body where you can visually see these loads (e.g., bunions, hammer toes) without imaging.
Micro Walk
A short, digestible walk, typically 5-10 minutes. Dr. Conley recommends these as 'movement snacks' to gradually increase daily step count and maintain activity, especially for those with chronic pain or low baseline activity.
Toe Spring
A characteristic in some shoes where the front of the shoe is curved upwards. Dr. Conley explains it facilitates the rocker of the foot, but can weaken intrinsic foot muscles if trained in constantly.
Shoe Spectrum
The concept of having different types of footwear for different purposes (e.g., 'workhorse shoe' for daily training, 'cheat shoe' for race day). Dr. Conley advocates for understanding when to use each to balance foot strengthening with performance.
Dorsiflexion
The movement of the ankle that brings the foot upwards towards the shin. Dr. Conley emphasizes its importance for movements like squatting, walking stairs, and preventing falls, noting that high heels can restrict it.
Overstriding
A running gait where the foot lands too far in front of the body's center of mass. Dr. Conley identifies this as a common problem that can lead to injury and reduced efficiency, especially when cushioned shoes mask the impact.
13 Questions Answered
Our feet are the foundation of our body, and their health significantly impacts overall physical, emotional, and mental well-being, influencing longevity, balance, and the ability to move without pain.
Common issues include bunions, neuromas (nerve irritation between toes), hammer toes (clawing of toes), plantar fasciitis (heel pain), and Achilles tendinopathy, all of which can lead to pain, decreased balance, and increased fall risk.
Walking an additional 500 steps a day can reduce cardiovascular mortality risk by 7%, and a 1,000-step increase can reduce all-cause mortality by 15%; 5,000 steps a day can reduce symptoms of depression, and 7,500 steps can reduce the prevalence of depression diagnosis.
A functional shoe should have a wide toe box allowing toes to splay, a 'zero drop' (heel and toe in the same plane), and be thin and flexible to allow the foot to feel the ground and strengthen naturally.
While cushioned shoes can feel good initially and offer performance benefits for race day, constant training in them can weaken the intrinsic muscles of the foot due to a loss of sensory perception and facilitated gait mechanics (like toe spring).
Taking 9,800 steps per day can significantly reduce the risk of dementia, with 3,800-4,000 steps providing 50% of the maximal benefit.
Insoles can be beneficial initially for acute pain by offloading the foot, but they should be part of an 'and conversation' that includes strengthening the foot, with the goal of eventually having an exit strategy for the insert.
High heels put additional pressure on the front of the foot, shorten muscles in the back of the leg, and change the function and structure of the foot, calf, hamstring, and back, leading to weakening of tissues over time.
It's not necessarily about standing versus sitting, but about incorporating movement breaks or 'movement snacks' like micro walks throughout the day to keep the system active and slowly increase step count.
While living on man-made surfaces makes constant barefoot walking difficult, the foot is designed to function and feel the ground. Strengthening the foot allows it to handle these loads better and interact with the environment more effectively.
Overstriding, where the foot lands too far in front of the body's center of mass, is a common issue that can cause pain and reduce efficiency, especially when cushioned shoes prevent the runner from feeling the impact.
These exercises do not mimic functional movements in the gait cycle; while they might initially 'wake up' the foot, they don't build functional strength for walking or running, and toe gripping is often a compensation for weak feet.
Hiking boots, despite providing a 'neurological hug' of stability, can restrict ankle dorsiflexion, transferring loads to the knee, and do not inherently make the ankle more stable; strengthening the ankle is a better long-term solution.
16 Actionable Insights
1. Prioritize Wide Toe Box Shoes
Choose shoes with a wide toe box that allows toes to splay naturally, as this is crucial for proper foot function, balance, and preventing common foot issues like bunions and neuromas. Ensure the width extends to the toes, not just the midfoot.
2. Select Zero Heel Drop Footwear
Opt for shoes with a “zero heel drop” (heel and toe in the same plane) to maintain proper foot alignment and prevent shortening of leg muscles. This supports the function and structure of the entire kinetic chain, including calves, hamstrings, and back.
3. Choose Thin, Flexible Soles
Select shoes with thin, flexible soles to allow your foot to feel the ground and engage its muscles more effectively. This strengthens the foot’s tissues, bones, ligaments, and tendons, whereas excessive cushioning reduces sensory perception and foot engagement.
4. Gradually Transition Footwear
When adopting minimalist or “barefoot” style shoes, transition gradually by starting with short periods (e.g., 10 minutes daily) and incorporating foot exercises. This allows your feet to strengthen and adapt to increased load, preventing potential pain or injury.
5. Increase Daily Step Count
Boost your daily step count by at least 500-1000 steps (equivalent to 5-10 minute “micro walks”) to significantly reduce risks of cardiovascular mortality, all-cause mortality, and symptoms of depression. Aim for 5,000-7,500 steps for mental health benefits.
6. Utilize Toe Spacers
Wear toe spacers regularly, especially in compatible wide-toe-box shoes, to encourage natural toe splay. This improves foot strength, ankle mobility, and overall kinetic chain function, counteracting the negative effects of narrow footwear.
7. Perform Toe Strengthening Exercises
Regularly practice toe yoga (lifting big toe, then four smaller toes, then all toes with splay and reach) and use resistance bands for toe curls and spreads. These exercises build intrinsic foot muscle strength, enhancing stability and reducing injury risk.
8. Roll Foot Bottom Daily
Roll the bottom of your feet with a ball for 60-90 seconds daily, particularly in the morning or after activity. This stimulates foot receptors, improving sensory perception and overall foot awareness.
9. Take Movement Breaks
Integrate frequent “movement snacks,” such as five-minute micro walks, throughout your day instead of prolonged static sitting or standing. This keeps your system active, contributes to your step count, and benefits overall health.
10. Strengthen Soleus Muscle
Strengthen your soleus muscle (lower calf) using single-leg seated calf raises (aim for 6 reps with 1.5x body weight) or standing calf raises (6 reps with 0.5x body weight). This muscle is vital for controlling ankle dorsiflexion and generating power.
11. Avoid Running Overstriding
When running, prevent overstriding by ensuring your foot strikes the ground as close to your center of mass as possible. Overstriding increases impact and can lead to injuries.
12. Add Plyometric Training
Incorporate plyometric exercises like jumping once or twice a week into your routine to increase running capacity by 2-4% and build a stronger, more resilient body. This is especially effective when combined with functional footwear.
13. Practice Ankle Inversion Exercises
Use a resistance band around your ankles to perform inversion exercises, driving your ankles outwards while keeping the ball of your foot on the ground. This strengthens key muscles for arch stability and foot control.
14. Perform Torso Rotations
While standing with your feet planted, rotate your torso as far as possible to each side, allowing your foot to change shape. This exercise enhances foot mobility and awareness by encouraging the arch to lower and increase.
15. Post-Restrictive Footwear Care
After wearing restrictive footwear (e.g., cleats, ski boots) for sports, dedicate time to foot care, including rolling the bottom of your foot and performing other foot exercises. This helps counteract stiffness and limited movement.
16. Avoid Relying on Hiking Boots
Do not rely on hiking boots for ankle stability, as they can restrict natural ankle dorsiflexion and transfer loads to the knee. Instead, focus on strengthening your ankles and improving their mobility for true stability.

5 Protocols
Foot Strengthening with Resistance Band (Four Toes)
Dr. Courtney Conley- Place your heel on the floor.
- Grab your four smaller toes with a resistance band.
- Press into the band and lift up, similar to a bicep curl with your toes.
- Perform 4 sets of 12 repetitions.
Foot Strengthening with Resistance Band (Big Toe)
Dr. Courtney Conley- Place your heel on the floor.
- Grab your big toe with a resistance band.
- Keep the ball of your big toe on the floor.
- Press into the band, feeling the tension in the arch of the foot and possibly the calf.
Foot Strengthening with Toe Strengthener Bands
Dr. Courtney Conley- Slide a resistance band around all your toes.
- Lift all your toes, trying to get your big toe to touch your finger (abduct) to strengthen the abductor hallucis muscle.
- Try to get your little toe to go out to strengthen the abductor digiti minimi.
- Lift all your toes, spread them, and reach them forward, ensuring the tripod of the foot (ball of big toe, ball of little toe, center of heel) remains on the ground.
- Press your toes to the ground as you spread them.
- Perform 30-40 repetitions a day.
Ankle Mobility and Arch Engagement (Standing Rotation)
Dr. Courtney Conley- Stand with your feet spread slightly, toes pointing straight ahead.
- Keep the ball of your foot on the floor.
- Drive your ankles outwards into a resistance band (if used), almost like you were going to sprain your ankle, keeping the big toe on the ground.
- Alternatively, with hands on your chest, rotate your torso to the left as far as possible, keeping your feet on the ground, to feel the arch of your foot increase.
- Rotate to the right to feel the arch lower.
- Perform 20 rotations as a movement break.
Transitioning to Functional Footwear
Dr. Courtney Conley- Begin by regularly performing foot exercises to build strength.
- Start wearing functional footwear (shoes with a wide toe box, zero drop, and thin/flexible sole) for 10 minutes a day.
- Gradually increase the duration of wearing functional footwear as your foot strength and comfort improve, allowing for a smooth transition.
