Strong feet, fast runners: how your foot strength shapes performance
1 June 2026The part of running most people overlook
You’ve just finished a run and feel tightness in your calves, a sore arch, or a niggle building in your shin, and your first thought is often “do I need different shoes?”. Most runners spend a lot of time thinking about footwear – cushioning, stability, carbon plates, stack height – but the part of the system doing the real work is often overlooked: your feet.
If you run regularly, your feet absorb thousands of impacts every session, adapt to the ground beneath you, stabilise your body, and generate the push-off that propels you forward. When your feet are strong and mobile, they handle this remarkably well, but when they’re not, other parts of the body often compensate, which is where many common running niggles begin to appear.
What your feet are actually doing
Your feet are complex and adaptable structures, comprising three arches, 26 bones, 33 joints, around 20 muscles with tendons, and more than an astonishing 100 ligaments – all working together. Their role goes far beyond simply holding you upright – acting instead as shock absorbers, stabilisers, and propulsion systems functioning in unison.
During running, the foot must perform several tasks almost instantly:
- Absorb impact
- Control movement through the arch
- Stabilise the ankle and lower leg
- Push the body forward for the next stride
If the muscles in the foot aren’t strong enough to manage these forces, the workload often shifts to the ankle, calf, shin, or even the knee and hip. At the Hub, we often see this pattern in runners dealing with persistent issues such as plantar heel pain, shin splints, or recurring calf tightness. In many cases, the underlying problem is that the foot hasn’t developed the strength or control needed to tolerate the training load.
Shoes help – but they can’t replace strength
Modern running shoes are impressive pieces of engineering, designed to improve comfort, reduce perceived impact, and in some cases, enhance performance. However, even the most advanced shoe cannot replace the role of your foot muscles – we say; “strength before shoes, and form before footwear”. Footwear works best when it complements the natural function of the foot rather than replacing it entirely. If the intrinsic muscles – the smaller stabilising muscles within the foot – are weak or underactive, the foot becomes more reliant on external support.
This does not mean that minimalist shoes or barefoot running are necessary for everyone, and conventional trainers remain the most practical and comfortable option for many. The key point is that your feet benefit from regular, targeted training just like any other part of your body.
Common myths about foot strength
One common misconception is that wearing the ‘right’ shoes is enough to keep your feet healthy. While shoes can help with comfort and impact reduction, they do not actively strengthen the foot. Another myth is that foot strength only matters if you run barefoot or in minimalist footwear, but evidence and clinical experience suggest otherwise. Strong, well-functioning feet are beneficial regardless of the shoe you wear, and they play a significant role in managing load, balance, and overall running efficiency.
We also often encounter the belief that foot exercises are only necessary if you already have pain. In practice, proactively developing foot strength tends to produce better outcomes and helps prevent problems before they appear.
The growing focus on foot strength
Recent years have seen increasing attention on foot strength in both sports science and rehabilitation. You may have noticed trends such as barefoot-style training, minimalist footwear, or rotating different types of running shoes. These approaches are based on the idea that allowing the foot to move and work naturally helps maintain strength and mobility.
The aim isn’t to abandon supportive footwear altogether. For many runners, conventional trainers remain the most comfortable and practical option. The goal is simply to ensure your feet are capable of handling load, whether you’re running in cushioned trainers, lighter racing shoes, or occasionally spending time barefoot. When building stronger feet, three areas tend to matter most:
- Toe strength: Your toes play a significant role in balance and push-off during running, and weak or inactive toes can reduce stability and efficiency during the final phase of your stride.
- Arch control: The arch acts like a spring, helping absorb impact and store energy as you move, and strong muscles around the arch improve how the foot manages these forces.
- Ankle mobility: Limited ankle movement can increase stress on the foot and shift load up the chain to the knees or hips.
Try what we call the ‘pen and penny’ foot core exercise. Stand barefoot, placing a 2p piece (or a piece of paper) under your big toe joint and a pen along the side of your longest longitudinal arch. Engage your foot core and, without leaning, lift the arch away from the pen while keeping the big toe pressed down on the 2p piece.
Practical ways to strengthen your feet
The good news is that building stronger feet doesn’t require complicated equipment or long gym sessions. Small, consistent exercises can make a meaningful difference over time.
Improve foot mobility
Maintaining good movement through the toes, arch, and ankle helps the foot adapt to different surfaces and loads. Simple exercises include:
- Spreading and lifting the toes
- Gentle ankle circles
- Calf and ankle mobility stretches
These movements keep the joints mobile and encourage the smaller stabilising muscles to remain active.
Add targeted strength work
Like any other muscle group, the feet respond well to gradual strengthening. Exercises often used in rehabilitation include:
- Towel scrunches using your toes
- Heel raises
- Controlled single-leg balance work
These movements strengthen both the foot and the muscles that support the ankle and lower leg.
Progress load gradually
If you’re interested in barefoot walking or minimalist-style running, progression is essential. Feet that have spent years in cushioned shoes may not be used to handling these forces directly. Start with short periods on safe surfaces and gradually increase exposure, giving tissues time to adapt. Sudden changes in footwear or running style are among the most common reasons people develop calf or foot injuries.
What we see in clinic
At The Rehab Hub, runners often come to us with recurring lower-leg injuries that appear to migrate from one area to another. One season it may be calf tightness, the next shin pain, and then perhaps irritation under the plantar fascia. When we assess these runners more closely, foot strength and control are often part of the picture. Improving strength and coordination at ground level frequently reduces stress placed on other areas, and for runners in particular, building foot and ankle strength alongside hip and glute strength tends to produce the most resilient results.
How we can help at the Hub
When someone presents with foot or lower-leg issues, we start by assessing how the foot interacts with the rest of the body, including:
- Foot mobility and strength
- Ankle range of motion
- Balance and single-leg control
- Running load and training patterns
From there, we build a rehabilitation plan that gradually increases the capacity of the foot and lower limb. For some people, this involves strengthening exercises and load management, while for others it may include adjusting footwear, running volume, or technique. The aim is always the same – to help the body tolerate the demands placed on it while reducing the risk of recurring issues.
Takeaway
Your shoes play a role in running comfort and performance, but they are only part of the picture. Strong, mobile feet provide the foundation for every step, helping absorb impact, stabilise your body, and generate efficient push-off. When that foundation is lacking, stress often shifts elsewhere, which can lead to recurring calf, shin, or knee issues. The good news is that foot strength can be improved with simple, consistent exercises, gradually building a stronger, more resilient foundation that supports comfortable and sustainable running.
