The Relationship Between Running Shoes and Injuries: A Complete Analysis of Over-Supportive Shoes, Minimalist Shoes, and the Latest Shoe Selection Science

The Century-Long Evolution of Running Shoes

Before the 1970s, running shoes had almost no cushioning. It wasn’t until Nike introduced air-cushioned running shoes that “technological cushioning” became the industry mainstream, with heel-to-toe drop continuously increasing, evolving from 10 mm up to a maximum of 15 mm. The logic of athletic shoe manufacturers was: more cushioning = fewer injuries.

However, a study published in 2009 by Harvard professor Daniel Lieberman changed all of this. He pointed out that barefoot runners naturally adopt a forefoot strike, and their impact forces are actually lower than those of heel-striking runners wearing thick-soled shoes. Subsequently, Christopher McDougall’s bestseller Born to Run sparked a “minimalist shoe revolution.”

Yet, after the minimalist shoe market emerged, the incidence of stress fractures (especially of the metatarsals) rose, revealing the dangers of overcorrection. Today’s sports medicine stance is: shoes themselves don’t cause “injuries”; injuries come from a mismatch between the shoe and the runner, or from transitioning too quickly.

Key Running Shoe Parameters Explained

Arch Type and Shoe Selection

Low Arch (Flat Feet):

• Feet tend toward overpronation
• Recommended: Stability running shoes, providing mild medial support
• Not recommended: Minimalist shoes (aggravate pronation)

Normal Arch:

• The most common foot type among runners
• Recommended: Neutral running shoes
• Not recommended: Overly controlling shoes (overcorrection)

High Arch:

• Feet tend toward supination/underpronation
• Recommended: Neutral or cushioned shoes, no additional support needed
• Note: High-arch runners have a higher risk of stress fractures

Assessment Method: The “wet foot test”—step with a wet foot onto a piece of cardboard and observe the footprint shape. Alternatively, get a gait analysis at a specialty running store.

Potential Problems with Over-Support Shoes

Over-support sounds reasonable in theory, but actual research results are quite complex:

• A 2022 study of 1,000 military recruits in training showed no significant difference in injury rates between those fitted with shoes based on foot type (control/stability/neutral) and those uniformly issued neutral shoes
• High-density medial support may lead to increased lateral pressure (near the 5th metatarsal and lateral malleolus)
• Over-reliance on shoe support may weaken the natural training of the foot’s intrinsic muscles

Current Research on Minimalist Shoes

Benefits and risks of minimalist shoes (Drop 0–4 mm, Stack Height < 20 mm):

Potential Benefits:

• Promotes strengthening of the foot’s intrinsic muscles
• Naturally guides forefoot/midfoot landing
• Improves proprioceptive feedback

Confirmed Risks:

• Transitioning too quickly leads to Achilles tendon overload (from a sudden drop reduction)
• Forefoot striking increases the risk of metatarsal stress fractures
• Requires a gradual adaptation period of 6–12 months; not suitable for sudden, complete transition

When to Replace Running Shoes

Running shoe midsole materials (EVA foam) gradually compress with use, and cushioning declines:

• Recommended replacement mileage: 600–800 km (adjusted based on runner weight and terrain)
• Heavier runners (>80 kg): replace at approximately 600 km
• Lighter runners (<60 kg): can extend to 900 km
• Use training shoes (for daily practice) and racing shoes (carbon-plated speed shoes) separately to extend the lifespan of both

Signs of Aging:

• Visible compression marks or creases on the midsole
• Increased joint fatigue after runs (beyond normal training fatigue)
• Outsole wear on the lateral side exceeding 3–4 mm

Practical Shoe Selection Tips

1. Shop for shoes in the afternoon: Feet swell slightly throughout the day, so trying on shoes in the afternoon is more accurate
2. Try on shoes with the type of technical socks you run in, of moderate thickness
3. Leave about 1 cm of space in front of the big toe (to avoid toe impact after long runs)
4. Don’t rely on a single brand: Sizing and fit vary greatly between brands; choose based on feel
5. Transition drop gradually: If switching from 10 mm to 4 mm, allow 3–6 months for the transition

Conclusion

There is no standard answer in shoe selection—only the shoe that “fits your current mileage, pace, foot type, and running habits.” Rather than chasing the latest technological materials, regularly assessing your foot’s needs, rotating shoes sensibly, and building foot strength are the fundamental ways to make your running shoes truly work for you.
