Should We Walk Barefoot? What the Science Says

Our feet spend most of the day inside shoes. But what happens when we take them off?

Walking barefoot changes the way our feet interact with the ground, influencing foot movement, pressure distribution and the mechanics of walking. These differences have sparked growing interest in barefoot training and minimalist footwear, particularly among runners.

But do these changes translate into stronger feet, fewer injuries or better performance?

A systematic review by Franklin and colleagues (2015) examined the differences between walking barefoot and wearing conventional footwear. Its findings offer useful insights—but also remind us that changing the way we move is not necessarily the same as improving it.

What Changes When We Walk Barefoot?

The researchers reviewed 15 studies selected from 466 articles identified through searches of six scientific databases. They examined differences in gait mechanics, including movement patterns, forces and muscle activity.

Several findings stood out:

• Foot shape: Walking barefoot allows the forefoot to spread more under load. Habitual barefoot walkers also tend to have wider feet anatomically, although this does not prove that walking barefoot alone causes the difference.

• Stride and cadence: Barefoot walking is generally associated with shorter steps or strides and a higher cadence compared with walking in conventional footwear.

• Foot placement: People tend to place the foot more flatly when walking barefoot, accompanied by changes in knee flexion and other aspects of gait.

• Impact forces: Some studies reported a lower peak vertical ground reaction force at initial contact when walking barefoot. This is a specific measurement, however, and does not mean that every tissue experiences less load.

• Plantar pressure: Habitual barefoot walkers showed lower peak plantar pressures and pressure impulses in the studies reviewed. In contrast, people accustomed to wearing shoes could experience higher peak plantar pressures when walking barefoot.

These results show that footwear influences how we walk. They do not establish that barefoot walking is universally better, nor that the same effects occur when running.

Does Walking Barefoot Make Your Feet Stronger?

This is where we need to distinguish what the review actually measured from what we might expect.

Walking barefoot allows the foot to move without the constraints of a conventional shoe. It may also expose the muscles and other tissues of the foot to different demands. However, the Franklin review focused on gait mechanics, not on demonstrating that barefoot walking strengthens the intrinsic foot muscles or prevents injuries.

Research on barefoot walking, minimalist footwear and specific foot-strengthening exercises addresses related but different questions. We should not treat them as interchangeable interventions.

The same caution applies to balance, proprioception and common foot conditions. Walking barefoot changes sensory input from the ground, but this review does not establish that it improves balance, treats plantar fasciitis or corrects bunions.

A change in movement mechanics is not automatically a health benefit. To establish a benefit, we need evidence that the change improves a meaningful outcome, such as strength, symptoms, function or injury risk.

How I Approach It

My transition to minimalist footwear took years, not weeks.

I started by walking barefoot at home. Later, I introduced minimalist shoes for short, occasional outings, gradually increasing their use as I became more comfortable. Today, I wear them daily.

I also do strength training barefoot when possible. In gyms where this isn't allowed, minimalist footwear can be an alternative for suitable exercises, while socks may work for some floor-based mobility drills if permitted and safe.

Running is a different story. Although minimalist running shoes exist, I wouldn't automatically make that transition. The demands are different, and there's no reason to change everything at once.

My experience isn't proof that this approach works for everyone. If you're curious about barefoot walking or minimalist footwear, start with short periods on safe surfaces and increase exposure gradually. Pay attention to how your feet, calves and Achilles tendons respond.

You don't need to abandon your shoes. Start by understanding your feet, experimenting gradually and finding what works for you.

Tu turno

Do you ever walk barefoot or use minimalist footwear? Have you noticed a difference in how your feet feel or function?
