In one possible embodiment, the inventive subject matter is directed to a foot covering, comprising: a thin, flexible compartment for receiving a foot. The compartment has a forefoot section, a midfoot section, and a rearfoot section of selected rigidity. The compartment has a top surface for securing the foot and a ground-facing surface having a sole divided into at least two portions comprising (1) a forefoot portion and midfoot portion and/or (2) a midfoot portion and a rearfoot portion. At least one sole portion comprises a midfoot portion disposed between a forefoot portion and/or a rearfoot portion. In the foot covering, each pair of sole portions is divided along a flexural line running generally transverse to the longitudinal axis of the foot. The sole portions and flexural line(s), in combination with the flexible compartment, have a material construction and are arranged so as to facilitate the close conforming of the foot covering to the foot of an intended user through plantar flexion to dorsiflexion.
