A corrective shoe insole system is configured to produce and promote a positive forefoot. A corrective shoe insole system includes an insole having a forefoot portion and a heel portion. The forefoot portion is be thicker than the heel portion to promote forefoot striking when walking or running. An insole may have one or more forefoot risers coupled thereto to provide a specific positive forefoot insole for the user. A user may gradually increase the thickness of live forefoot portion of the insole by adding or changing out forefoot risers. This gradual increase in forefoot thickness of the insole may prevent injury and muscle strain from the adjusted foot striking position. A forefoot riser may be detachably attachable to the forefoot portion of the insole and an attachment feature may provide positive and secure attachment to prevent movement of the forefoot riser.

The present invention is a system of footwear that is easily customizable and provides the wearer with a wide variety of removeable and interchangeable upper portions in various colors, patterns, shapes and styles, allowing the wearer to create numerous different shoe looks from the same, single pair of soles. The shoe design specifically comprises a base portion having numerous metal snaps with male connectors (ball heads) spaced at intervals along the sides. The corresponding female connectors are located on the undersides of the interchangeable uppers; the other side of the uppers, which can be seen while wearing the shoe, contains rounded metal caps.

Footwear with a heel portion having a clasp member with resilient arms having locking tabs that engage with locking slots in a receptacle member in a main portion, when the heel portion abuts against the main Portion. The locking tabs disengage from the locking slots when simultaneously squeezed together by a tool that extends through locking tab access holes on both sides of the main portion. The locking tab access holes are too small for a child's fingers to enter. The clasp member and receptacle member can be in either the heel portion or the main portion.

Footwear includes upper, midsole, and exterior sole components. One side of the upper component includes a first plurality of openings. This first plurality of openings includes two openings separated by a strip of upper component material. The midsole component is received in the upper component and includes a plurality of protrusions extending through the openings of the upper component. The strip of upper component material covers a first portion of the midsole component located in a recess between the first and second protrusions. The exterior sole component is engaged with the midsole component and includes a second plurality of openings. The plurality of protrusions extend through corresponding openings of this second plurality of openings. A strip of exterior sole component material located between two of the second plurality of openings at least partially covers the strip of upper component material.

An article of footwear includes an upper having an internal volume adapted to receive a foot of a wearer and a sole structure secured to the upper. The sole structure includes a chassis plate provided within the upper, a midsole secured to the chassis plate such that the upper extends between the chassis plate and the midsole, and an outsole tread element attached to a ground facing surface of the midsole.

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.

A convertible high heel and flat shoe, comprising a sole including a heel section; and a high heel piece positionable between a high heel mode where the high heel piece supports the heel section and a flat shoe mode where the high heel piece is received within the sole.

Footwear with a heel portion having a clasp member with resilient arms having locking tabs that engage with locking slots in a receptacle member in a main portion, when the heel portion abuts against the main portion. The locking tabs disengage from the locking slots when simultaneously squeezed together by a tool that extends through locking tab access holes on both sides of the main portion. The locking tab access holes are too small for a child's fingers to enter. The clasp member and receptacle member can be in either the heel portion or the main portion.

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.

Presented are footwear sole structures with split midsole designs having peripheral walls for lateral stability, footwear fabricated with such sole structures, and methods for making/using such footwear and/or sole structures. A sole structure for an article of footwear includes mating first and second midsole sections each having a respective midsole sidewall that extends between and adjoins respective upper and lower midsole surfaces. The first midsole section's lower surface has a first waveform geometry, such as an anteroposterior-undulating curviform wave, and the second midsole section's upper surface has a complementary, mirrored waveform geometry that seats therein and intermeshes with the first waveform geometry. The second midsole section includes one or more peripheral walls that extend upward from the second sidewall; inboard surfaces of the peripheral wall(s) abut outboard surfaces the first sidewall. An outsole, which defines the footwear's ground-contacting surface, is attached to the lower surface of the second midsole section.
