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.[1]
These sandals are favoured by minimalist runners for several reasons. They force the foot and the runner to run with a natural gait. They also help protect the foot from glass, gravel, and other debris.[1]
In Christopher McDougall's book Born to Run, the author describes the Rarámuri of the Mexican Copper Canyons teaching a fellow runner how to build huaraches.[1]
There is also well-known model of Nike running shoes[2] of the same name, which however is not a huarache type of a shoe.
