Abstract
An article of footwear that includes a sole defining a bending feature (e.g., a groove) between a phalanges portion and a metatarsus portion of the sole. The bending feature allows the phalanges sole portion to articulate upward with respect to the metatarsus sole portion. An upper is attached to the sole and defines a foot void for receiving a human foot. The upper has a phalanges portion that defines at least one toe receiver volume. The at least one toe receiver volume defines a raised shape with respect to an adjacent metatarsus portion of the upper. Articulation of the phalanges sole portion and substantially unrestricted toe lift movement into the at least one toe receiver volume allows substantially unrestricted upward toe flexion of a received foot in the foot void.
