Disclosed herein is a fastening structure which enables objects to be easily removeably coupled, and enables a smooth slideable coupling and decoupling. The fastening structure includes a male and female component. The male component is cross shaped with a wing member and cross bar member. The female component has a complementary structure with an elongate slot and cross groove, such that the male component is slideably received and mated.

A customizable combination shoe and accessory include: (a) a wearable mule or slide type shoe having: (i) a sole portion having an insole and an outsole, (ii) a vamp arranged at the insole, (iii) a heel affixed to the outsole, and (iv) a single anchor extending through the outsole; and (b) an accessory harness having: (i) a portion defining an opening, the opening being configured to engage the single anchor to removably secure the portion of the harness to the anchor at the outsole, and (ii) support portions, extending from the portion defining the opening, configured to engage portions of the foot of a wearer of the combination shoe and accessory to provide support to the engaged portions of the foot of the wearer.

A sandal with a magnetically connected upper straps uses a multilayered sole, multiple strap-attachment coupler, and a removable upper to enable a user to modify the sandal's appearance. The strap-attachment couplers are fasteners which are used to attach the removable upper to the multilayered sole. To accomplish this the strap-attachment couplers includes a connector-receiving receptacle and an upper-fastening mechanism. The removable upper includes multiple strap segments, each of which is connected to a connector insert. Inserting the connector insert into the connector-receiving receptacle enables the upper-fastening mechanism to become coupled to the connector inserts, thus tethering the removable upper to the multilayered sole. Additionally, the strap-attachment couplers are distributed across the insole, such that the strap-attachment couplers enable the user to create a desired type of sandal.

Methods of forming an article of footwear using a multipart strobel structure and a resulting article of footwear comprising an upper with a transition strip are described. The transition strip that has an outer perimeter edge, an inner perimeter edge, and a width between the outer perimeter edge and the inner perimeter edge, with the inner perimeter edge defining an internal opening of the transition strip, and the inner strobel that has an outer perimeter edge. The inner strobel is positioned in an overlapping relationship with the transition strip and temporarily attached.

An article of footwear includes an upper attached to a stabilizer, an outsole, a first pod, and a second pod. The stabilizer has a lower surface and a first securing mechanism. The outsole has a first retention mechanism and an interior surface. The first securing mechanism is retained by the first retention mechanism. A volume between the lower surface and the interior surface forms a midsole cavity. The midsole cavity receives the first pod and the second pod.

A convertible shoe may include a sole and a plurality of interchangeable heel portions, each selectively attachable to the sole. The heel portions may each include a mounting surface configured to interface with a heel receiver of the sole. The heel receiver may include a fixed hook and a movable hook, with the movable hook being operable by an actuator coupled to a bottom surface of the sole. In some examples, an upper is secured to the sole of the shoe by one or more clamping plates. In some examples, the sole of the shoe is configured to be biased into a default bend corresponding to a high-heeled state even when a low heel is attached to the heel receiver.

Footwear is provided and comprises a bottom part comprising a sole and an integral rear upper section, and a separate top part comprising a front upper section. The parts are releasably connected to each other by a releasable fastener. Each part provides a fastener half and each fastener half has a start and an end. The rear upper section of the bottom part includes a heel cap portion. The top part comprises two ends at a rear part thereof and the ends are connected by a strap positioned between the start and end of the top half fastener, and a movable flap is provided and extends over the inside surface of at least part of the heel cap portion. The releasable fastener is a zipper fastener, in which each fastener half has a zipper track with a plurality of teeth, and the number of teeth on the halves is exactly the same.

Footwear with interchangeable or removable components comprised of an outsole unit, a midsole unit, a flexible material (also known as an upper unit), and a rigid pin-like device that may be placed inside an opening or series of openings, which are formed through the combination of said midsole unit and said outsole unit. Once assembled, the embodiment forms a unified shoe.
