Running has become increasingly popular over the years and provides numerous health benefits including improved cardiovascular health,decreased risk of stroke and hypertension, increased bone mass[1] and psychological benefits such as decreased depression and a positive effect on mood state. Despite its popularity and many benefits runners still experience a high injury rate,with up to 79 % of runners incurring an injury annually[2].Thus, runners have sought numerous strategies in hopes of reducing injury and running faster. One strategy is to run without any shoes at all:Bare foot[3]

Despite the benefits of footwear, interest in barefoot running has increased among the running community, with proposed benefits including a decreased injury rate. Advocates tout the evolutionary success of man as a barefoot bipedal runner. There is also speculation that the development of modern footwear and the associated altered running gait patterns (including a hindfoot strike versus the forefoot or midfoot strike typical of unshod runners) have contributed to injuries seen in runners[4].

Humans are maladapted to wearing shoes in some ways that contribute to certain injuries. From an evolutional medical perspective, three novel consequences of wearing shoes may be relevant to injury :[5]

  • Shoes limit proprioception: Sensory feedback from the plantar surface of the foot works as an adaptation for sensing characteristics of the ground including hardness, roughness, unevenness, and the presence of potentially dangerous objects such as sharp rocks. Plantar proprioception activates reflexes and helps the central nervous system make decisions that help increase stability and avoid injury.
  • Modern shoes with elevated heels, stiff soles, cushioning, and arch support may either facilitate or encourage a different running form than appears to be common among habitual barefoot runners.
  • Shoes can contribute to weak and inflexible feet, especially during childhood when the foot is growing.[5]


Most studies of barefoot running were conducted by asking habitually shod runners to take their shoes off in a laboratory.However,using only habitually shod runners to study barefoot running is problematic because one cannot expect such subjects to have developed the musculoskeletal adaptations and kinematic habits of habitual barefoot runners.Barefoot runners have more variable kinematics than shod runners because they experience more proprioception from their feet.
