After observing the ancient and superhuman running culture of the Tarahumara people in Mexico, McDougall concluded that humans evolved running barefoot. He argues that the advancements in running shoes have, ironically, led to more harm than good. The solution to the rise in running related injury is to go barefoot or, in case of sharp objects, use minimalist sandals.

10 Reasons to go barefoot with minimalist sandals
Barefoot sandals and minimalist sandals: Enhanced running efficiency
Research has shown that running barefoot can result in up to 8% increase in efficiency (Squadrone & Gallozzi 2008, Warne 2013). It is not clear why this is, though it is likely to be due in part to the toes and the arches of the foot are allowed to function more effectively, and the way removing the shoe encourages a forefoot strike (Lieberman 2010) which means the Achilles and calf muscle are used more efficiently.
Barefoot sandals and minimalist sandals:Facilitated venous return resulting in
- a. Decreased blood pressure, This is true – particularly if walking on uneven ground (ie cobbled streets or off road). The walking itself, of course, helps to support good cardiovascular function but, in addition, the fact that the foot strikes the ground at a slightly different angle with each step and is allowed to roll over the naturally convex heel (rather than a flat, straight, rubber plate) means that multiple muscle groups are activated resulting in greater pumping of blood back through the valve-based venous system (Vines 2005).
- b. Reduced risk of deep vein thrombosis; For the same reason as above (2a) there is less pooling of blood in the lower leg and enhance venous return.
- c. Lower incidence of varicose veins; because there is better venous return, blood does not sit in the veins increasing pressure on the vein walls and creating varicosities. Instead, it is pumped more efficiently back to the heart through enhanced muscular use in the lower leg.
Barefoot sandals and minimalist sandals:Decreased ankle sprains;
- It is claimed that increased awareness of foot position from direct contact with the ground (Robbins et al., 1995) may decrease risk of ankle sprain – and/or the reduced leverage and consequently twisting around the ankle (sub-talar) joint from going “barefoot” minimizes the risk of spraining the joint during a stumble (Stacoff et al., 1996).
Barefoot sandals and minimalist sandals:Lowered risk of shin splints;
- Chronic ailments such as shin splints, iliotibial band syndrome and peri-patellar pain are attributed variously to the altered biomechanical loading of the limbs (Siff and Verkhoshansky, 1999, p.451). When running barefoot on hard surfaces, the runner compensates for the lack of cushioning underfoot by plantar-flexing the foot at contact, thus giving a softer landing (Frederick, 1986).
- Barefoot runners also land mid-foot, increasing the work of the foot’s soft tissue support structures, thereby increasing their strength and possibly reducing the risk of injury (Yessis 2000, p.124).
Barefoot sandals and minimalist sandals:Minimize back pain;
- Walking barefoot means, inherently, that the only heel you’re walking on is your own. Walking wearing standard shoe means, almost inevitably, you’ll have an extra heel. Any change in the orientation of the heel instantly changes the mechanics of the arch of the foot, but importantly also changes the mechanics of the low back – increasing the curve. An increased curve in the low back means that the small facet joints on the back of the spine which are not designed for weight bearing (Bogduk 2003) become loaded and, across time, painful.
Barefoot sandals and minimalist sandals:Enhance proprioception
- 70% of the body’s terminal nerve endings finish in the hands and feet. Of course, if you look to the evolution of vertebrates you find that they progressed from fish to tetrapods (ie forelimbs and hindlimbs in touch with the ground) then finally to bipeds. Bipedalism not only requires significant balance but, by definition, means that our only two consistent points of contact with our surrounding environment are our feet. This is reflected by the fact that there are 200,000 sensory nerve endings in the sole of the foot – more than anywhere else in the body.
Barefoot sandals and minimalist sandals:Strengthen intrinsic foot musculature
- just as when you support a broken limb with plaster the muscles weaken and atrophy, so when you support afoot the muscles weaken and atrophy. Weak muscles make for greater injury risk, greater dependency on shoes, and impaired performance. Don’t let yourself become a statistic.
Barefoot sandals and minimalist sandals:Maximize biomechanical performance
- funnily enough, the arches of the foot evolved that way not by chance, but for a reason. Counter to the commonly held belief that the arches are there to absorb shock, in actuality the arches are designed to store energy and return that energy to the gait cycle on the next step.
- Similarly, the natural arches of the spine are designed to perfectly store energy as the body “derotates” during the gait cycle (Gracovetsky 1988, 1997, 2001). Wearing shoes that “support” the arch prevents the arches from performing their function, while any change in heel height above that of the forefoot results in changes to the spinal curves compromising energy storage and recoil in these two key areas for efficiency and performance.
Barefoot sandals and minimalist sandals:Diminish risk of bunions;
- the traditional shape of shoes means that they round to a point somewhere in front of the 2nd or 3rd toe. This means that the big toe is often pushed towards the middle of the foot and the same is true of the little toe. This phenomenon coupled with a heel on the shoe – which loads the big toe even further – results in a deviation of the big toe called hallux valgus and ultimately bunions may develop.
Barefoot sandals and minimalist sandals:Optimise balance / prevent falls;
- we mentioned above (point 6) that the feet provide significant sensory feedback to the brain and are therefore critical in balance and efficient gait. However, it is sad to learn that the leading cause of death in people of the age of 65 years is not heart attacks, not cancer and not strokes – but falling (Chek 2004). In fact, 25% of elderly people who fall and fracture a hip, die within 1 year of that fall.
Atrophy: A lack of nutrition to a tissue, resulting in wasting of that tissue.
Tetrapod: A creature which habitually stands on four limbs.
Gait cycle: The repetitive cyclical motion of walking or running.
Venous return: The return of blood, via the veins, from the periphery toward the heart.
