Vibram FiveFingers is a type of minimalist shoe produced by Vibram, originally marketed as a more natural alternative to outdoor activities (sailing, kayaking, canoeing, and as a camp shoe or after shoes). Footwear is meant to replicate barefoot and has a thin and flexible sole that is contoured with the shape of a human foot, including the individual parts that are visible to the toes. The company resolved a lawsuit claiming a false health claim and set aside $ 3.75 million to pay a return of up to $ 94 to anyone who has purchased the product since March 21, 2009.

Origin
Invented in 1999 by Robert Fliri, a design student from Vinschgau who wanted to "figure out how to move in nature better." Vibram FiveFingers was developed and introduced in 2005.
Destination
Vibram FiveFingers was originally targeted to yacht racers to maintain a grip on the slippery deck without sacrificing a barefoot experience. Their potential use as minimalist running shoes was suggested to Vibram CEO by Ted McDonald, a runner who earned the nickname "Barefoot Ted" for his lifeless feet and a successful career as a footless run coach. The purpose of this shoe outlined by the manufacturer is to provide footwear that is primarily used for fitness, running, water sports, yoga, trekking and travel, and other sports.

Style
Vibram FiveFingers comes in a variety of styles and sizes, including FiveFingers KMD Sport, KMD Sport LS, Classic, Sprint, Flow, KSO (most popular), TrekSport, KSO Trek, Bikila (named Abebe Bikila), Bikila LS, Speed ​​and style men FiveFingers Spyridon, Tracks LS and Bormio and women's style FiveFingers Jaya and Jaya LR. Kids KSO, Sprint and Speed ​​styles are available.
Sizing
Unlike traditional footwear, Vibram FiveFingers does not follow the typical US or British shoe scale. They require exact foot length measurements with an accuracy of 1/8 inch (3 mm) and conversion to the FiveFingers measurement chart. It ranges from 38-50 for men, 34-42 for women, and 29-36 for children. As a result, shoe size closely reflects the EU system. However, there is little difference between the size of women and men, so, for example. , the size of 39 women is not the same as the size of 39 men.
Materials
Vibram FiveFingers consists of many different materials that vary depending on the style of the shoe. The most common component is the Vibram TC-1 performance rubber, which forms the sole of this shoe, a thin stretch polyamide comprising a shoe frame that forms the contours of the user's foot, and antimicrobial microfiber footwear.
Minimalist Shoes
In a report in an article in Nature Nature, co-author Daniel E. Lieberman stated that "People who wear conventional running shoes tend to walk with strikes that are much different from those who wear minimalist or barefoot shoes. landed in the middle or front of the foot, footwear runners have almost no impact collision. "Research Lieberman et al is an experiment involving five groups of runners from Kenya and the United States. Both American groups are adult athletes who have run with shoes since childhood, and those who are used to running barefoot or with minimal footwear like Vibram FiveFingers (mentioned in the research). The three Kenyan groups are adults who never run with shoes until late teenagers, as well as two teen groups: those who wear shoes and who always run barefoot. The runners are ordered to run on a power plate embedded in a 25-meter track, and recorded during the run using a three-dimensional infrared kinematic system. This measurement is used to assess the pattern in which the feet touch the ground and how to forcibly do it.
Health effects
Walking barefoot, which is similar to walking with FiveFingers, seems to reduce the risk of ankle sprain and plantar fasciitis. Because Fivefingers does not have support or cushioning (or at least), the goal is to allow the user to use natural foot attacks, as if he would walk barefoot. Incorrect and unnatural running forms, especially when heel attacks are involved, produce equally uncomfortable or painful feedback when walking barefoot, thus causing the user to adjust his or her pace. This feedback is said to be filtered from public running shoes due to thick soles, thus causing possible injury.
If unconditionally slow enough, especially when moving away from the heel of the foot or wearing shoes with high heels, the sole of the foot or the plantar fascia may become inflamed or damaged by activity. Also because of overwork or wrong form, runners may experience Achilles tendonitis or inflammation and metatarsal fractures. Over-striding in Vibram FiveFingers, that is, landing with legs too far ahead of one's hip, adds unnecessary extra stress to the calf muscles, Achilles tendon, and the arch of the foot, which can cause serious health problems if left untreated.
One study found that more new FiveFingers users showed an increase in bone marrow edema than in the control group of the study. It recommends the transition to use shoes to be very slow and gradual.
Claim
In 2012, an initial lawsuit filed against Vibram for claims made about their minimalist FiveFingers shoes. Vibram claims that shoes "reduce [s] leg injury and strengthen the leg muscles". Although Vibram has "explicitly" refused "actual or potential mistakes or responsibilities", on May 7, 2014 it was announced that the company had moved to settle the lawsuit and agreed to set aside $ 3.75 million to pay a return of up to $ 94 to anyone who has bought the product since March 21, 2009.
