The Science Behind Barefoot Shoes: What the Latest Research Reveals

For years, barefoot shoe enthusiasts across Ireland have championed the benefits of minimalist footwear based on personal experience and anecdotal evidence. Now, cutting-edge scientific research is confirming what many have long suspected: barefoot shoes offer significant, measurable advantages for foot health and function.

 

Groundbreaking 2025 Research

A comprehensive systematic review published in November 2025 in the Journal of Clinical Medicine has provided the most robust evidence to date on the benefits of barefoot and minimalist footwear training. The research team, led by Celia Rodríguez-Longobardo and colleagues at Universidad Politécnica de Madrid, analysed seven high-quality studies involving 213 participants to understand exactly how barefoot training affects our feet.

 

What the Research Found

 

Stronger, Healthier Foot Muscles

The most striking finding was the significant increase in both intrinsic and extrinsic foot muscle development. Participants who trained in barefoot or minimalist shoes showed measurable growth in key muscles including:

 

• Flexor digitorum brevis
• Quadratus plantae
• Flexor hallucis brevis
• Gastrocnemius
• Soleus

 

The forefoot region showed the most prominent muscle hypertrophy, suggesting that barefoot shoes allow these often-neglected muscles to engage and strengthen naturally.

 

Enhanced Strength and Function

Beyond muscle size, the research confirmed functional improvements that matter in daily life:

 

• Increased toe flexor strength – Better grip and stability with each step
• Enhanced metatarsophalangeal joint strength – Improved push-off power
• Better medial arch mechanics – Natural arch support from within
• Greater navicular height – Healthier foot structure

 

Superior Neuromuscular Control

 

Perhaps most fascinating were the neuromuscular adaptations observed in barefoot shoe users:

 

• Reduced tibialis anterior activity (less compensatory muscle tension)
• Increased gastrocnemius pre-activation (better impact preparation)
• More efficient stride patterns
• Faster stabilisation during ground contact
• Enhanced proprioception and balance

 

The Injury Prevention Connection

 

The research team highlighted an important implication: these adaptations may help prevent common foot and lower limb injuries. Conditions like plantar fasciitis and Achilles tendinopathy have been linked to weakness in foot muscles. By naturally strengthening these structures, barefoot shoes may offer a preventive approach to foot health.

This is particularly relevant for Irish customers dealing with flat feet, sensitive feet, and plantar fasciitis – conditions we frequently hear about from our community.

 

What Works Best?

 

Not all barefoot training approaches were equally effective. The research revealed that:

 

Most Effective:

• Progressive programmes lasting 8+ weeks
• Combination of strength, agility, and balance exercises
• Higher intensity functional movements
• Gradual transition from conventional footwear

Less Effective:

• Short interventions under 8 weeks
• Isolated foot exercises only
• Low-intensity programmes

 

This suggests that simply wearing barefoot shoes during normal activities – whether you're walking through Dublin city centre or hiking in Wicklow – combined with varied movement patterns, provides optimal benefits.

 

Why This Matters for Irish Barefoot Shoe Wearers

 

At BarefootShoes.ie, we've long heard from our customers about the comfort, quality, and health benefits they experience with brands like Leguano, Belenka, and Barebarics. This research validates what you've been telling us.

The science confirms that barefoot shoes aren't just a trend – they're a scientifically-supported approach to building stronger, healthier, more functional feet.

 

Making the Transition

 

For those considering the switch to barefoot shoes, the science is clear: with a gradual transition and consistent use over 8+ weeks, you can expect measurable improvements in foot muscle strength, arch function, balance, and overall foot health.

 

Our team at BarefootShoes.ie is here to help you make that transition safely, with individual size charts for each brand and expert guidance on finding the perfect fit.

 

The Bottom Line

 

This systematic review represents the highest quality evidence to date supporting barefoot and minimalist footwear. Whether you're dealing with foot problems or simply want to improve your foot health naturally, the research backs up what our Irish customers have been experiencing firsthand.
