A sole structure for an article of footwear having a midsole having a support surface extending from a posterior end to an anterior end, the midsole having an outer surface and an inner surface, wherein the support surface and the inner surface surround a cavity, the midsole also including an inner rail extending along the inner surface and into the cavity, wherein the rail and the cavity are configured to engage with a removable outsole.

Midsoles for a sports shoe that comprise a ground facing component comprising a rim portion with a first inward-facing wedge-shaped elongate protrusion and a foot support component arranged slidably at least partially inside the ground facing component. The foot support component may comprise a first outward facing wedge-shaped elongate recess configured to receive the first inward-facing wedge-shaped elongate protrusion of the ground facing component such that the foot support component tilts when sliding towards the rim portion of the ground facing component.

A shoe system is disclosed. The system includes a first shoe portion including one or more plugs extending from the first shoe portion. The system further includes a second shoe portion including one or more apertures formed in the second shoe portion and sized to receive the one or more plugs of the first shoe portion. The second shoe portion is configured to be removably connected to the first shoe portion when the one or more plugs of the first shoe portion are received in the one or more apertures of the second shoe portion. The first and second shoe portions may each consist of a single injection piece from EVA foam. The second shoe portion may further include a tread portion configured to make the second shoe portion have desirable characteristics for a given situation or usage, for example, to make the second shoe portion oil- and/or slip-resistant.

Footwear includes upper, midsole, and exterior sole components. One side of the upper component includes a first plurality of openings. This first plurality of openings includes two openings separated by a strip of upper component material. The midsole component is received in the upper component and includes a plurality of protrusions extending through the openings of the upper component. The strip of upper component material covers a first portion of the midsole component located in a recess between the first and second protrusions. The exterior sole component is engaged with the midsole component and includes a second plurality of openings. The plurality of protrusions extend through corresponding openings of this second plurality of openings. A strip of exterior sole component material located between two of the second plurality of openings at least partially covers the strip of upper component material.

A shoe comprising a sole comprising a female element; and an upper arrangement comprising a corresponding male element configured to be received in the female element upon insertion in an insertion direction. The male and female elements comprise complementary locking features including a first locking feature being provided on a peripheral surface of one of the male or female elements, and a second locking feature being provided on a peripheral surface of the other of the male or female elements. The first locking feature comprises a protrusion that protrudes in a direction transverse to the insertion direction, and the second locking feature comprises a locking recess. The locking protrusion is configured to engage with the locking recess as the male element is inserted into the female element, thereby locking the sole to the upper arrangement.

Articles of footwear comprising modular parts. The modular parts can comprise a first part having a first surface and a second part having a second surface opposing the first surface. A first connector couples the first part to the second part and is integrally formed with the first part. A second connector couples the second part to the first part and is integrally formed with the second part. The first surface and the second surface are mated by the first connector and the second connector.

An article of footwear includes an upper attached to a sole structure to define an interior cavity and a closure system. The sole structure includes a forefoot region, a midfoot region, and a heel region. The closure system includes a closure mechanism, a securing element and a cord that is operably engaged with the upper of the footwear and the closure mechanism. The closure mechanism is actuated to adjust the footwear from a loosened configuration to a tightened configuration. The securing element extends across the upper from a medial side to a lateral side. The securing element only partially covers a winding region formed by the cord proximate a tongue of the footwear. The securing element has a fixed end that is permanently fastened to the sole structure.

A shock absorber has a first and second end surfaces opposite to each other in an axial direction, and a plurality of connection surfaces. The first end surface is an N-sided polygon (N is an integer of 3 or more), and the second end surface is an M-sided polygon (M is an integer of 4 or more and more than N). (MN) vertices are provided at intermediate positions in the axial direction on a circumferential surface defined by the plurality of connection surfaces. From the vertices, one first ridgeline reaches one vertex of the first end surface and two second ridgelines reach a corresponding one of two vertices of the second end surface. The remaining vertices are connected to each other by (2NM) third ridgelines. The first ridgeline, the second ridgelines, and the third ridgelines define the plurality of connection surfaces.

Midsoles for a sports shoe that comprise a ground facing component comprising a rim portion with a first inward-facing wedge-shaped elongate protrusion and a foot support component arranged slidably at least partially inside the ground facing component. The foot support component may comprise a first outward facing wedge-shaped elongate recess configured to receive the first inward-facing wedge-shaped elongate protrusion of the ground facing component such that the foot support component tilts when sliding towards the rim portion of the ground facing component.

Describes are support elements for a sole of a shoe, in particular a sports shoe, a sole and a shoe with such a support element, as well as a method for the manufacture of a support element. As examples, the support element includes a first partial member formed of a first material, and a second partial member formed of a second material. The first partial member is mechanically joined to the second partial member in a connection region, wherein the connection region is configured to allow the first partial member to rotate or slide relative to the second partial member. The first partial member, the second partial member, and the connection region can be co-molded and joined together in a single fabricating step.
