Wearing the wrong type of shoe for walking or running can affect performance, comfort, and even one’s long‑term foot health, experts warn.
Podiatrists say understanding the biomechanical differences between the two can help prevent pain and injury and it matters more than many realise.

The force of the feet carries a force that travels up one’s legs and into their joints. When walking, the foot stays in contact with the ground longer and moves in a smooth heel‑to‑toe roll, but when running, there are brief moments where both feet are off the ground and the forces involved increase significantly.
According to podiatrists and trainers, running can place about two to three times your body weight on your feet with each stride, while walking exerts lower forces more consistently. This fundamental difference in mechanics is the reason walking shoes and running shoes are built so differently.
Podiatrist Dr Nikhil Boga explains that walking shoes are designed to allow the foot to bend and roll naturally with each step, prioritising flexibility and stability. In contrast, running shoes feature more cushioning and shock absorptionthroughout the sole to help cope with impact at higher speed.

The higher cushioning in running shoes particularly helps protect knees and hips from repeated stress during runs protection walkers don’t necessarily need.
Walking shoes often have a lower heel‑to‑toe drop and a firmer midsole, which helps maintain balance and supports the gait’s natural progression from heel strike to toe push‑off.
Running shoes, meanwhile are engineered to deliver energy return and forward propulsion, with a more pronounced heel‑to‑toe drop that aids in absorbing impact forces and optimising forward motion.
Statistics from recent running gear surveys show that over 70 % of runners report injuries each year, and many of these are linked to improper footwear use including runners who use shoes not suited to their gait or mileage.
Less than one in ten runners has ever undergone a professional gait analysis, a tool that could help match shoe design to individual biomechanics and reduce injury risk.
Choosing the wrong shoe can have a ripple effect up the body. For example, wearing walking shoes for running can leave the foot inadequately protected against high‑impact forces, increasing the risk of shin splints, plantar fasciitis, or Achilles tendon problems.
Conversely, using heavily cushioned running shoes for long walks can change how the foot meets the ground and feels unstable during a leisurely, extended stride.
Finding the right footwear begins with knowing your activity and understanding how your foot moves during it. Many specialty running stores offer gait analysis that helps classify foot type — whether neutral, over‑pronating, or supinating — and recommends shoes that work with your foot mechanics, rather than against them.
Historically, people may not have given much thought to their shoes beyond comfort or style, but podiatrists emphasise that footwear plays a major role in long‑term foot and joint health.
Walking shoes support the walker’s natural movement pattern and reduce strain during prolonged use, while running shoes are engineered specifically for the impact and propulsion of running.
For casual walkers, using running shoes most of the time might not lead to immediate issues, but experts warn that over prolonged periods the mismatch in design priorities can lead to discomfort or fatigue, particularly in the lower back, knees or feet. For runners, the stakes are higher.
They are repeated high‑impact cycles without proper shock absorption which can accelerate wear on joints or contribute to overuse injuries.
Footwear also impacts posture and balance, especially in older adults or those who walk frequently for fitness. A shoe with appropriate support can improve gait efficiency, helping distribute forces evenly and reducing cumulative stress on muscles and ligaments.
Selecting the right shoe isn’t just about performance; it’s about long-term wellbeing. Footwear serves as the foundation for virtually every activity that involves walking or running, and the cumulative effects of improper support can manifest over time, sometimes in ways that aren’t immediately noticeable.
Misalignment in your shoes can lead to subtle changes in posture, gait, and muscle engagement, gradually increasing the risk of overuse injuries, chronic joint stress, and even back pain. While understanding the biomechanical demands of your chosen activity and selecting shoes designed specifically for that movement, you can protect your body and enhance your comfort, efficiency, and overall health.
Studies suggest that over 25 % of walking-related injuries are linked to footwear that fails to adequately support this natural motion, highlighting the importance of choosing shoes that stabilise the foot without restricting movement.
Proper walking shoes not only reduce the risk of blisters, plantar fasciitis, and shin splints but also encourage a smoother, more energy-efficient stride, making everyday activity feel easier and more enjoyable.
With runners, the stakes are higher. Every stride generates significant impact forces often two to three times body weight that travel through the feet, ankles, knees, and hips. Running shoes are engineered to absorb this shock, provide propulsion, and maintain stability during high-speed motion.
Wearing walking shoes for running may seem harmless at first, but the insufficient cushioning and different heel-to-toe drop can lead to stress injuries such as shin splints, Achilles tendinitis, and knee pain over time.
Similarly, runners who wear worn-out or improperly fitted running shoes risk overuse injuries, reduced performance, and slower recovery. According to surveys of recreational runners, over 70 % report injuries annually, many linked to inappropriate footwear or failure to replace shoes after they reach the end of their usable lifespan.
Beyond injury prevention, the right shoe also affects posture, balance, and energy efficiency. Properly fitted footwear supports the arches, cushions impact, and allows muscles to function optimally, which can reduce fatigue during longer sessions.
Older adults, in particular, benefit from shoes that provide stability and grip, as these features reduce the risk of falls a serious concern for public health. Even small adjustments, like selecting a shoe with the correct heel-to-toe drop or sole stiffness, can influence how forces are distributed across joints, helping maintain comfort and mobility over years of walking or running.
Ultimately, choosing the right footwear is about aligning your shoes with your personal activity profile, foot structure, and movement patterns. It requires attention to fit, cushioning, arch support, and durability.
Even casual walkers can benefit from a gait analysis or professional fitting to ensure their shoes complement their natural motion. With runners, periodic assessment of shoe wear, mileage, and gait mechanics is equally important.
When matching shoes to the demands of one’s activity, an investment in comfort, performance occurs, and long-term health helping you remain active, injury-free, and confident in every step you take.
