The Vibram FiveFingers are a type of minimalist shoe manufactured by Vibram, originally marketed as a more natural alternative for outdoor activities (sailing, kayaking, canoeing, and as a camping or after-hike shoe). [1] The footwear is meant to replicate being barefoot and has thin, flexible soles that are contoured to the shape of the human foot, including visible individual sections for the toes. [2] The company settled a lawsuit in 2014 alleging false health claims and set aside $3.75 million to pay refunds of up to $94 to anyone who had purchased the product since March 21, 2009. [3]
Invented by Robert Fliri, a design student from Vinschgau who wanted to "figure out a way to move around in nature better." Vibram FiveFingers were developed and introduced in 2005. [2] [4] [5] [6] [7] [8]
Vibram FiveFingers were originally targeted to yacht racers to maintain grip on slippery decks without compromising the barefoot experience. [9] Their potential use as a minimalist running shoe was suggested by the Vibram USA CEO to Ted McDonald, a runner who earned the nickname "Barefoot Ted" and ran in the shoes during the 2006 Boston Marathon as part of the brand launch. [10] The purpose of these shoes as outlined by the manufacturers is to provide footwear to be mainly used for fitness, running, water sports, yoga, trekking and traveling, and other sports. [11]
Vibram FiveFingers comprise many different materials that vary depending on the style of shoe. The most common components are Vibram TC-1 performance rubber, which makes up the sole of these shoes, a thin stretch polyamide comprising the frame of the shoe that molds to the contours of the user's foot, and an antimicrobial microfiber footbed.[ citation needed ] Shoe sizes correspond to quarter-inch increments in foot length, closely resembling the Continental European system. [12]
In addition to their standard models, Vibram has collaborated with fashion labels to develop designer footwear on three occasions: a $1,300 "Toe" shoe released by Balenciaga, a shoe with painted nails produced by Japanese footwear brand Suicoke and label Midorikawa, and a shoe based on traditional sneakers from Suicoke and designer Takahiro Miyashita. [13]
In a report on an article in Nature , co-author Daniel E. Lieberman (whose research was partially funded by Vibram) stated that "People who wear conventional running shoes tend to run with a significantly different strike than those who run in minimalist shoes or barefoot. More specifically, the ball of the foot should strike the ground before the heel when running (or walking) barefoot or in minimalist shoes. By landing on the middle or front of the foot, barefoot runners have almost no impact collision." [14] [15] Lieberman has "emphasized that his research does not include data on injury or show that barefoot running is better for you" but that it is "a reasonable hypothesis that needs to be tested". [16] Lieberman et al.'s study was an experiment that involved five groups of runners from Kenya and the United States. The two American groups were adult athletes who had run with shoes since childhood, and those who habitually run barefoot or with minimal footwear such as Vibram FiveFingers (mentioned by name in the study). The three Kenyan groups were adults who had never run in shoes until late adolescence, as well as two teenage groups: those that habitually wore shoes and those that always ran barefoot. The runners were instructed to run over a force plate that was embedded in a 25-meter track, and were recorded during the run using a three-dimensional infrared kinematic system. These measurements were used to assess the pattern with which the foot strikes the ground and how forcibly it does so. [17]
Barefoot running, which is similar to running with FiveFingers on, appears to decrease the risk of ankle sprain and plantar fasciitis. [18]
If not conditioned slowly enough, especially when transitioning away from heelstrike running or from wearing shoes with an elevated heel, the sole of the foot or plantar fascia can become inflamed or damaged with activity. [17] Also due to over-training or incorrect form, runners may experience Achilles tendonitis or metatarsal inflammation and fractures. Over-striding in Vibram FiveFingers, that is, landing with the foot too far in front of one's hips, adds extra unnecessary stress to the calf muscles, Achilles tendon, and the arch of the foot, which can lead to serious health problems if not addressed. [17]
One study found a greater number of new wearers of FiveFingers showed an increase in bone marrow edema than those in the study's control group. [19] It recommended transition to use of the shoe be very slow and gradual.
In 2012, an initial lawsuit was filed against Vibram over claims made about their FiveFingers minimalist shoe. Vibram claimed that the shoe "reduce[s] foot injuries and strengthen[s] foot muscles". The claim was based on Gert-Peter Bruggermann research accepted at the 2005 Conference for the International Society of Biomechanics. While Vibram has "expressly" denied "any actual or potential fault ... or liability", on May 7, 2014, it was announced that company has moved to settle the suit and agreed to set aside $3.75 million to pay refunds of up to $94 to anyone who had purchased the product since March 21, 2009. [3]
In 2015, the family of deceased Ethiopian Olympic runner Abebe Bikila filed a lawsuit against Vibram for using and trademarking the Bikila name without permission. The suit was dismissed in 2016 on the basis that the Bikila family unreasonably delayed in seeking to enforce their rights. The family had become aware of Vibram's use of the Bikila name in 2011. Following the dismissal, the Bikila family's attorney stated that "Vibram has never asked the Bikila Family for permission, nor compensated them for using Abebe Bikila’s personality." [20]
The foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground. This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
A shoe is an item of footwear intended to protect and comfort the human foot. Though the human foot can adapt to varied terrains and climate conditions, it is vulnerable, and shoes provide protection. Form was originally tied to function but over time shoes also became fashion items. Some shoes are worn as safety equipment, such as steel-toe boots, which are required footwear at industrial worksites.
Shambel Abebe Bikila was an Ethiopian marathon runner who was a back-to-back Olympic marathon champion. He is the first Ethiopian Olympic gold medalist, winning his and Africa's first gold medal at the 1960 Summer Olympics in Rome while running barefoot. At the 1964 Tokyo Olympics, he won his second gold medal. In turn, he became the first athlete to successfully defend an Olympic marathon title. In both victories, he ran in world record time.
A gait is a manner of limb movements made during locomotion. Human gaits are the various ways in which humans can move, either naturally or as a result of specialized training. Human gait is defined as bipedal forward propulsion of the center of gravity of the human body, in which there are sinuous movements of different segments of the body with little energy spent. Varied gaits are characterized by differences such as limb movement patterns, overall velocity, forces, kinetic and potential energy cycles, and changes in contact with the ground.
Toe socks are socks that have been knitted so that each toe is individually encased the same way as fingers within a glove.
Racing flats, or simply flats, are lightweight athletic shoes designed for "long distance" track and field, cross country, and most often, road races. They differ from normal training shoes mainly by the lack of a substantial heel to toe drop.
The arches of the foot, formed by the tarsal and metatarsal bones, strengthened by ligaments and tendons, allow the foot to support the weight of the body in the erect posture with the least weight.

Barefoot running, also called "natural running", is the act of running without footwear. With the advent of modern footwear, running barefoot has become less common in most parts of the world but is still practiced in parts of Africa and Latin America. In some Western countries, barefoot running has grown in popularity due to perceived health benefits.
Vibram S.p.A. is an Italian company based in Albizzate, Italy, that both manufactures and licenses the production of Vibram-branded rubber outsoles for footwear. The company is named after its founder, Vitale Bramani, who is credited with inventing the first rubber lug soles. Vibram soles were first used on mountaineering boots, replacing leather soles fitted with hobnails or steel cleats which were commonly used up until then. The soles produced by Vibram are called Vibram soles, Vibram rubber or simply Vibram.
Vivobarefoot is a minimalist running shoe company. Their technology, invented by Tim Brennan and developed by British shoe company Terra Plana, is aimed at offering the optimum biomechanics and posture commonly associated with walking barefoot and barefoot running, and advocated within the barefoot movement and barefoot running community. Their marketing describes the walking experience as "as close to going barefoot in the city as you can get." The most prominent shoe using this technology is their Evo running shoe.
Locomotor effects of shoes are the way in which the physical characteristics or components of shoes influence the locomotion neuromechanics of a person. Depending on the characteristics of the shoes, the effects are various, ranging from alteration in balance and posture, muscle activity of different muscles as measured by electromyography (EMG), and the impact force. There are many different types of shoes that exist, such as running, walking, loafers, high heels, sandals, slippers, work boots, dress shoes, and many more. However, a typical shoe will be composed of an insole, midsole, outsole, and heels, if any. In an unshod condition, where one is without any shoes, the locomotor effects are primarily observed in the heel strike patterns and resulting impact forces generated on the ground.
Huaraches are an open type of outdoor footwear, consisting of a sole held to the wearer's foot by straps passing over the instep and around the ankle. The common understanding is that these sandals were a variant of traditional Mexican huaraches, the difference being in design and construction.
Altra Running, commonly known as Altra, is an American manufacturing company engaged in the design, development, marketing, and sales of athletic shoes for road running, trail running, and general footwear. Since 2018 Altra is owned by VF Corporation, an American global apparel and footwear company with other brands like Icebreaker, The North Face, Vans, JanSport, Eastpak and Timberland.
Minimalist shoes are shoes intended to closely approximate barefoot running or walking conditions in comparison to traditional shoes. Minimalist shoes are defined as providing "minimal interference with the natural movement of the foot, because of its high flexibility, low heel to toe drop, weight and stack height, and the absence of motion control and stability devices." Minimalist shoes provide more sensory contact for the foot on the ground while simultaneously providing the feet with some protection from ground hazards and conditions. Research shows that wearing a minimalist shoe can help improve running economy, foot strength and arch function.
Softstar Shoes is an American shoe manufacturer and retailer based in Philomath, Oregon. It is known for its minimalist or barefoot-style shoes and has been recognized as an early participant in the movement to encourage minimalist footwear.
Barefoot is the state of not wearing any footwear.
Running injuries affect about half of runners annually. The frequencies of various RRI depend on the type of running, such as speed and mileage. Some injuries are acute, caused by sudden overstress, such as side stitch, strains, and sprains. Many of the common injuries that affect runners are chronic, developing over longer periods as the result of overuse. Common overuse injuries include shin splints, stress fractures, Achilles tendinitis, Iliotibial band syndrome, Patellofemoral pain, and plantar fasciitis.
The toe box is the section of footwear that surrounds the toes on closed-toe shoes. Toe boxes that are too tight can cause injuries and foot deformities, whereas wider toe boxes may be used to treat or prevent common foot conditions such as Morton's neuroma. Toe boxes come in a variety of shapes and styles of construction, some of which are a matter of fashion, and some of which are designed for specialized functions.
