A walking-assisted air-jet insole includes an insole base. A plurality of pressed-air outlet units that can generate airflow based on stepping pressure are provided on the insole base; the pressed-air outlet unit includes a cavity for retaining air. An upper part of the insole base is provided with an upper air hole that communicates with the cavity, and a lower part of the insole base is provided with an air sac part that is elastically deformed and restored based on the stepping pressure. A volume of the cavity can be changed based on the elastic deformation and restoration of the air sac part. A lower end of the air sac part is provided with a convex column that moves up and down based on the stepping pressure. The cavity includes an upper cavity portion and a lower cavity portion from top to bottom.

Embodiments of the present invention relate to a shoe construction that includes an upper that has an interior surface and a corrugated exterior surface of rapid manufactured material. The upper interior surface and corrugated exterior surface form a lattice-interlace surface. The lattice-interlace surface includes the interior surface that has a plurality of horizontal laths, the corrugated exterior that has a plurality of vertical laths, and a plurality of lattice apertures that extend from an interior of the shoe to an exterior of the shoe. The shoe construction further includes an interior sole portion of sintered material. The interior sole portion forms a tessellated framework. The tessellated framework includes a lattice of hollow cubes; each hollow cube has a top surface opening and a bottom surface opening, the openings extending from an interior of the shoe to an exterior of the shoe.

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.

A shoe with an upper that is at least partially rendered impermeable, including a sole; an insole; an upper assembly, which at least comprises a breathable lining, a breathable upper, and, interposed between at least part thereof, a layer that is waterproof and is fixed hermetically below the insole, the upper assembly being associated with the insole; and a region providing a waterproof seal of the insole to the sole, the sealing region substantially surrounding the breathable or perforated portion that is free for perspiration.

An immobility system for a free-fall environment includes an immobility device including at least one suction cup configured to engage the immobility device to a surface, and a valve that, when activated, results in release of the at least one suction cup from engagement with the surface. A remote controller is spaced apart from the valve and is configured to selectably transmit an activation signal to the valve. An immobility device includes at least one suction cup configured to engage the immobility device to a surface, and a valve that, when activated, results in release of the at least one suction cup from engagement with the surface. A receiver at the device is configured to receive an activation signal and activate the valve.

Sole structures, foot support systems, articles of footwear, and/or other foot-receiving devices include: (a) a first footwear component having a ground-facing surface, wherein a forefoot portion of the ground-facing surface includes arched medial and lateral surfaces and (b) a second footwear component having an upper-facing surface, wherein a forefoot portion of the upper-facing surface includes arched medial and lateral surfaces that face (and optionally contact) the respective arched medial and lateral surfaces of the first footwear component. The first and second footwear components are movably engaged together such that: (a) the arched medial surface of the first footwear component moves with respect to and along the arched medial surface of the second footwear component and (b) the arched lateral surface of the first footwear component moves with respect to and along the arched lateral surface of the second footwear component.
