Provided is a walkable shoe having a glass-like appearance. The shoe has a heel portion, a sole portion provided on the heel portion, and an upper portion provided on the sole portion; wherein the heel portion and the sole portion are made almost entirely of an organic glass, and the upper portion is made almost entirely of an organic glass.

Footwear comprising: a sole having a supporting surface with a groove, and an upper including a coupling portion, which is reversibly insertable inside the groove, wherein the groove is shaped to prevent axial sliding of the coupling portion when in the groove. A reversible coupling device reversibly couples the upper to the sole, between an operational configuration, where coupling portion is in the groove to prevent the extraction of the respective coupling portion along the insertion direction, and a non-operational configuration, where the coupling portion and the at least one groove are not constrained to each other so that the upper and the sole are separated or separable, and vice versa. The reversible coupling device includes first coupling elements fixed in the groove and second coupling elements fixed to the coupling portion, which are mutually reversibly couplable, said first and second coupling elements defining a quick fastening/unfastening system.

Articles of footwear include one or more expandable lugs (e.g., inflatable lugs) to hold at least some footwear component parts together. The expandable lug(s) may be included as part of an impact force-attenuating component (e.g., a fluid-filled bladder) for the article of footwear. The expandable lug(s) extend into receptacle(s) provided in a foot support component in an unexpanded (e.g., deflated or low-pressure) condition. Once within the receptacle(s), the expandable lug(s) are changed to an expanded (e.g., inflated or high-pressure) condition. The expanded lug(s) engage bearing surfaces provided inside the receptacle(s) to prevent the lugs from pulling out of the receptacles. The use of such expandable lugs for securing footwear component parts together may enable easy assembly of footwear components without use of adhesives and/or separate hardware components, which can enhance the recyclability, sustainability, and environmental friendliness of articles of footwear and their production methods.

Footwear with a modular sole assembly having an insole portion connected to an upper. The insole portion can have a compressible lattice with interconnected laths to provide support for the wearer's foot. A midsole portion is connected to the insole portion and has a midsole perimeter portion that interfaces with the insole perimeter portion. The midsole portion is modularly affixed to the insole portion. An outsole portion is connected to the midsole portion. First locking features are integrally formed along the lower perimeter portion of the upper or along the insole perimeter portion. Second locking features are integrally formed along the midsole portion and configured to releasably mate with the first locking features and fixedly hold the midsole portion together with the insole portion and the upper without use of cement bonding or other adhesive material.

The present disclosure relates to a leg protector. According to an aspect of the present disclosure, disclosed is a leg protector which can protect a wearer's foot and leg and is made of an elastic material, the leg protector comprising: a bottom plate part for supporting a wearer's foot; and a protection part connected to the upper side of the bottom plate part, extending upward therefrom, and formed to cover at least a part of the side and rear portions of the wearer's foot and leg, wherein the protection part includes, on both the left and right sides of the ankle portion thereof, an opening part through which regions corresponding to the wearer's malleoli are exposed to the outside.

A shoe assembly comprises a base shoe (10), a removable outsole (25) and a removable cover (22). The base shoe (10) is defined by a skeleton insole (11) having a lower surface, a heel component (12), and an upper (13) rising from the periphery of the skeleton insole (11). The upper (13) defines a foot-retaining element. The removable outsole (25) is connected to the skeleton insole (11) to overlie the lower surface thereof. There is a releasable mechanism having a first part on the skeleton insole (11) and a second part on the outsole (25) to interconnect the two. The removable cover (22) is for the upper (13), and fits over the base shoe (10) to overlie the foot-retaining element. The cover (22) has a sole region provided with a sole opening for accommodation of the releasable mechanism interconnecting the outsole (25) with the skeleton insole (11). The cover (22) also has a heel opening (23) through which at least a part of the heel component (12) passes. A part of the cover (22) is located between the lower surface of the skeleton insole (11) and the outsole (25), to retain the cover (22) on the base shoe (10).

A shoe having a removable sole is provided. The shoe includes one or more straps that are insertable through corresponding apertures in the soles to attach a sole to a base of the shoe. The removable soles provide a shoe with capability to interchange soles, thereby providing for specialized soles to supply for a single shoe, which allows use of the shoe with various athletic sports.

The footwear includes a sole having three holes passing through the sole. A front channel, a first rear channel and a second rear channel are formed in an underside of the sole. The footwear also includes of a strap having a front plug, a first rear plug, and a second rear plug connected to the strap. Each of the three holes in the sole are aligned with respective channels to enable the three respective plugs to pass through each respective hole. The three plugs are releasably attached to the sole and configured to allow a user's foot to be located between the strap and the sole. Each respective plug is completely located within a respective channel such that each respective plug sits flush with the underside of the sole to secure the strap to the sole. The three channels and the three plugs are of complementary size and shape.

Disclosed is a shoe system which comprises a shoe, at least one clip, and at least one detachable upper. The shoe has a midsole portion having a sidewall surface extending around the shoe, and at least one elongated channel defined in and extending along at least a portion of the sidewall surface. The elongated channel is configured for receiving the clip in a locking fashion. The clip has a locking portion for locking within the channel. The clip connects with the detachable upper via a connection portion.

An interchangeable shoe. The interchangeable shoe includes a base, where the base includes a footbed, and an upper. The interchangeable shoe also includes an attachment, where the attachment releasably attaches the upper to the base, The attachment includes a groove in the footbed and a rail attached to the upper, where the rail is configured to be inserted into or removed from the groove.
