Present aspects are directed to a braided upper comprising a tubular braided structure, which comprises an internal cavity and a plurality of apertures. The yarn of the tubular braided structure surrounds a perimeter of each of the plurality of apertures. The braided upper comprises a midsole positioned within the internal cavity and comprising a plurality of braid-receiving features mated with the yarn of the tubular braided structure. The braided upper and the midsole are keyed to one another when the yarn is mated with the plurality of braid-receiving features.

The invention includes a shoe system including a sole having attached fasteners and interchangeable uppers having complementary fasteners. In other embodiments, the invention includes particular uppers that may be used in such a shoe system.

An article of footwear comprising a sole constructed for receiving a foot having a toe section and an ankle section with at least two loops fixedly attached to the toe section; an interchangeable upper, or several interchangeable uppers, having loops for securing the upper to the loops of the sole of the footwear; such uppers and soles attached by specialized clips adapted to facilitate a wide variety of advantages.

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.

A medical shoe having an overmolding layer with a non-uniform density is provided. The medical shoe may include a midsole configured to support a foot, and a frame surrounding the midsole. The midsole may include a foot receiving portion forming a substantially planar surface for supporting the foot and a frame receiving portion opposite the foot receiving portion. The frame may include an overmolding layer extending from a side of the frame opposite the midsole so as to form a ground contacting surface. The overmolding layer may have a non-uniform density. The sole assembly may be secured to the frame by a self-locking fit between the sole assembly and the frame.

A shoe comprising an upper, a midsole coupled to the upper and comprising a recess proximal to a junction between the upper and the midsole, a midsole insert comprising a channel, the midsole insert configured to seat within the recess, and a shoe panel configured to detachably couple to the upper of the shoe, the shoe panel comprising a first end configured to seat within the channel of the midsole insert. The shoe panel may be a midfoot or heel panel and may be detachably coupled to the upper by a hook and loop closure. The shoe may be a slip on shoe comprising a tongue side extension that is tucked under a quarter extension to allow a midfoot panel to smoothly couple to the upper over the tongue.

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.

The invention includes a shoe system including a sole having attached fasteners and interchangeable uppers having complementary fasteners. In other embodiments, the invention includes particular uppers that may be used in such a shoe system.

A shoe system including a shoe upper with a bottom side having an aperture extending to a cavity. The shoe system also includes a selectively removable outsole which includes a bottom for contacting the ground, and a top for engaging with the bottom of the shoe upper. The top side of the outsole further includes a projection which is sized and shaped to extend through the aperture and into the cavity when the outsole is in a first orientation, which is misaligned with respect to the shoe upper. The projection is also sized and shaped to fit within the cavity but no longer back through the aperture when the outsole is in a second orientation, which is aligned with respect to the shoe upper. In the second orientation, the projection within said cavity prevents disengagement of the outsole from the shoe upper.

The three invention's utility designs can be used for all types of footwear, including slippers and sandals for indoors, outdoors, SPA, hotel slippers and etc. The first core invention are removable and washable insoles/socks that are pulled over/attached to the base/hard insole of slippers with options when upper parts are also detachable. The second invention is the closed-toes slippers with ventilation holes both on the cloth insole and upper part with option to have it combined with the first invention. The third invention's distinction is the giant size of slippers that are worn over the outdoor footwear that can also have options with the removable sock or ventilation holes from inventions mentioned earlier. There are different details variations described in specifications for all three interrelated inventions. These slippers provide more hygiene, can be worn longer, which is more economical for households and reduces waste produced by slippers.
