An outsole for a shoe including first and second sole segments that overlap at least partially. The first sole segment can include at least one stud and be arranged at least in a mid-foot portion of the outsole. The second sole segment can include at least one stud and be arranged at least in a toe portion of the outsole. In some embodiments, the outsole can include a first cushion element arranged between the first sole segment and the second sole segment and overlapping with at least one first stud of the first or second sole segment. In some embodiments, the outsole can include a second cushion element being arranged between the first sole segment and the second sole segment and overlapping with at least one second stud of the first or second sole segment. In some embodiments, the outsole may be an outsole for a football shoe.

A sole structure for an article of footwear comprises a sole plate that has a forefoot portion with a foot-facing surface. The sole plate has at least one groove extending at least partially transversely in the foot-facing surface. The at least one groove is open when the sole structure is dorsiflexed in a first portion of a flexion range, and closed when the sole structure is dorsiflexed in a second portion of the flexion range that includes flex angles greater than in the first portion of the flexion range.

A device for use in a shoe includes a first foot, a second foot, a third foot, a fourth foot, a first flexible leg, a second flexible leg, a third flexible leg, and a fourth flexible leg. The first flexible leg extends from the first foot and is curved. The second flexible leg extends from the second foot and is curved. The third flexible leg extends from the third foot and is curved. The fourth flexible leg extends from the fourth foot and is curved. The first flexible leg, second flexible leg, third flexible leg, and fourth flexible leg are joined together with each other at a common area. The first flexible leg, second flexible leg, third flexible leg, and fourth flexible leg are configured to store energy when a force is applied to the common area, and to return energy when the force is removed from the common area.

An outsole for an article of footwear with a forefoot region, a midfoot region, a heel region, a medial side, and a lateral side. The outsole can include a ground engaging surface with a plurality of cleats and a plurality of circular ridges including a first set of circular ridges and a second set of circular ridges. The first set of circular ridges can be concentrically aligned about a first epicenter in the forefoot region and the second set of circular ridges can be concentrically aligned about a second epicenter in the heel region. The plurality of cleats can include a first set of cleats in the forefoot region that can be aligned along a first circular ridge of the first set of circular ridges.

An article of footwear includes an upper and a sole coupled to the upper. The sole includes one or more elongate shape memory components that define a cavity and form a midsole.

Soles for articles of footwear including a mechanically anisotropic three-dimensional mesh. The mechanically anisotropic three-dimensional mesh can include one or more mechanically anisotropic regions with a first lattice shear modulus measured in a first direction and a second lattice shear modulus measured in a second direction opposite to or orthogonal to the first direction. The first and second lattice shear moduli are different to provide the three-dimensional mesh with mechanically anisotropic properties. The mechanically anisotropic three-dimensional mesh can be three-dimensionally printed.

An article of footwear includes an upper, a midsole connected to the upper, and an outsole connected to the midsole. The midsole includes a platform extending along a perimeter portion of the midsole and a lattice structure integrally formed with the platform, the lattice structure including a network of laths.

The disclosed embodiments relate to portions of an article of footwear formed from an extruded member. In certain embodiments, a sole or portion of a sole can be formed from one or more extruded members. In certain embodiments, the extruded member can be a single, continuous piece of solid material. In certain embodiments, a sole for an article of footwear can be fashioned from an extruded member formed in a controlled geometric pattern. In certain embodiments, the sole can include one or more layers.

A sole having respective forefoot, midfoot and backfoot parts, which are contiguous in a longitudinal direction running from toe to heel, and including a stiffening shank extending in the longitudinal direction from toe to heel. The shank extends over a predominant portion of the longitudinal development from the backfoot part to the forefoot part, and has areas of different flexibility alternating along the longitudinal development, the flexibility of these areas being progressively variable in a substantially continuous manner between one area and the contiguous areas.

A device configured to surround a portion of a foot-receiving cavity at a heel region of an article of footwear comprises a control bar having a center segment, a first side arm extending from the center segment, and a second side arm spaced from the first side arm and extending from the center segment. The control bar may include a series of slats. A base supports the control bar and is connected to the first side arm and the second side arm. The control bar is biased to an unstressed position with the center segment a first distance from the base, and elastically bends under an applied force to a loaded position with the center segment a second distance from the base less than the first distance. The device stores potential energy that returns the control bar to the unloaded position upon removal of the applied load.
