An interlocking mechanism for a shoe can provide the ability for the shoe sole to be attached or removed. For example, a shoe wearer may want the ability to change his or her shoe soles for aesthetic purposes. The shoe sole can also comprise additional functionality for the shoe wearer. For example, the shoe sole itself provide storage and/or lighting capabilities.

A footwear construction capable of incorporating one to three or more platform layers, or no platform layers at all. The invention comprises a kit including a sneaker member, optionally includable in the final construction first second and third platform members, guide members, optionally in sets of three, suitable for inclusion in a constructed footwear item with one, two or three platform members, and a tread its sole member, optionally replaceable by other types of soles.

A foldable footwear device may include a fore sole, having a fore upper surface and a fore lower surface, and an aft sole, having an aft upper surface and an aft lower surface. A hinge may pivotally couple the fore sole to the aft sole. The hinge may be configured to enable the fore sole and the aft sole to be moved between a planar position in which the fore upper surface and the aft upper surface may be substantially parallel and continuous with each other and a folded position in which the fore lower surface and aft lower surface may be contacting each other. A fore distal fastener may be coupled to the fore sole, and an aft distal fastener may be coupled to the aft sole. The fore distal fastener may removably engage with the aft distal fastener to secure the device in the folded position.

The present invention relates to a modular shoe (1700) in particular a sports shoe, with a sock like outer shoe (1750) and a frame (1710). The sock like outer shoe is provided for a releasable arrangement around the frame. The sock like outer shoe may comprise a plurality of profile elements (1765), wherein at least one of the profile elements extends from an outer side of the sock like outer shoe. A region of the at least one of the profile elements may be configured to releasably engage in a formfitting manner with a lower side of the frame of the modular shoe.

The transformable shoe is an apparatus that allows a user to customize the height of the shoe. The apparatus includes a shoe body, a collapsible heel, and a lift-receiving bed. The shoe body surrounds and supports the foot against the ground. The collapsible heel uplifts the shoe body above the ground. More specifically, the collapsible heel uplifts a heel seat above the ground and defines an arch of the foot. The collapsible heel includes a plurality of anthropomorphic members. The height of the apparatus is dependent on the arrangement of the plurality of anthropomorphic members with each other, moreover the plurality of anthropomorphic members may be arranged into a high-heel configuration, a wedge configuration, and a flat configuration. In order to secure the configuration, a telescopic extrusion is integrated into a distal member of the collapsible heel. The telescopic extrusion connects the distal member to the lift-receiving bed.

An article of footwear having a removable outsole, midsole, and upper is provided. A portion of the upper may have a perimeter lip that may be coupled to a perimeter channel in an upper surface or side of the outsole. The midsole may be securely placed into the upper to further secure the upper to the outsole. The fit of the outsole, upper, and midsole generates a securely assembled article of footwear ready for user wear. In aspects, the removable outsole, midsole, and upper may be changed to customize the article footwear for the user.

A work shoe, in particular a safety shoe, includes at least one passive protection unit which is intended to passively protect a shoe wearer at least against mechanical and/or electrical loads, and includes at least one active protection unit which has at least one sensor unit which is intended to detect at least one characteristic variable at least in order to enable a protection function and/or a comfort function. The sensor unit is configured at least for detecting at least one person-related characteristic variable and/or at least one environmental characteristic variable.

An insole for open-styled footwear that includes a mating attachment system for variably affixing the insole into footwear.

An ankle/foot orthosis includes an orthosis boot that is attached to an adjustor unit that positions a sole offset from the orthosis boot. The adjuster unit provides angular adjustments of an inclination of the sole relative to the orthosis boot to accommodate a specific condition of the user's foot by rotation of wedged rotary plates to provide corrective alignment of the user's foot relative to a support surface during walking.
