Minimalist and Barefoot Running Shoes: What the Evidence Says About Injury Risk
Minimalist and barefoot-style running shoes promise a more "natural" stride, but the injury-prevention story is more nuanced than marketing suggests.
How the biomechanics change
Biomechanical studies consistently show that running barefoot or in minimalist shoes shifts most runners toward a forefoot or midfoot strike, lowers vertical loading rates at initial contact, and increases stride cadence. At the same time, these shoes reduce energy absorption at the knee joint while increasing energy absorption at the ankle joint.
A trade-off, not a fix
That shift matters clinically: research summarized in a 2025 systematic review on barefoot and minimalist footwear-based training found that clinical outcome studies show equivocal overall injury rates between minimalist and traditional running shoes — but the type of injury tends to change. Runners who switch may see improvement in prior knee-related complaints, while facing a higher risk of calf, Achilles tendon, and metatarsal stress injuries, especially when the transition happens too quickly.
Why transition speed is the real risk factor
The clearest, most consistent finding across the literature is that abrupt switching — jumping straight from a heavily cushioned trainer into a zero-drop minimalist shoe for regular mileage — is what drives the increased injury rate, not the minimalist design itself. Foot and calf muscles need weeks to months to adapt to the higher mechanical demand.
Practical takeaways
- If you're curious about minimalist shoes, transition gradually over several weeks to months, not days.
- Build calf and foot intrinsic muscle strength before increasing minimalist mileage.
- Don't switch shoe type simply because you have a nagging injury — match the switch to a specific biomechanical goal, ideally with guidance from a sports physiotherapist or podiatrist.
Helpful products
- Minimalist running shoes — a lower-drop option for runners easing into a more natural stride.
- Resistance band for calf raises — supports the gradual strength-building a minimalist transition requires.
