Definitions

  • the invention relates to footwear with removable and replaceable tread or sole to convert the shoe from one style or configuration to another, for example to change from a dress or casual shoe to a golf shoe.
  • the core modules are all inherently flat and of uniform thickness so the overall height of the shoe is altered but not the height of the heel in relation to the toe.
  • the core modules are positioned by a series of corresponding holes and insertable pins, and held together by mating hook and loop material.
  • the lip is located on the perimeter of the shoe components and the recess cuts into the perimeter of the lower shoe component.
  • the perimeter lip aligns with the recess in the perimeter, but is not inserted into the recess and does not lock the components into place.
  • U.S. Pat. No. 3,902,259 issued Sept. 2, 1975 to Cracco, discloses a sandal with interchangeable side plates and sole.
  • the side plates and sole can be removed and replaced through a series of interlocking slots and the components are positioned with corresponding projections and holes.
  • the side plates and sole can be altered to alter the look of the sandal, and in one embodiment a flat sole can be replaced with a sole with a wedge heel to convert the shoe from a low heel to a higher heel.
  • Cracco does not disclose the use of an intermediate insertable component to alter a low heel into a high heel, and involves multiple components with a complicated locking mechanism.
  • U.S. Pat. No. 5,317,822 issued June 7, 1994 to Johnson is drawn to an athletic shoe with an interchangeable wear sole, or sole tread.
  • the purpose is to allow the user to alter the tread to best match the tread to the surface of the athletic play area.
  • the sole is positioned by an interlocking ridge and channel and by a series of knobs and knob chambers that correspond to align the components, and the sole is held in place by Velcro hook and loop material and a series of lock brackets with locking pins placed around the perimeter of the sole. Both the base of the upper and the interchangeable soles are flat, and the attachment surface between the upper and sole is flat.
  • U.S. Pat. No. 7,549,237 issued on June 23, 2009 to Gallegos discloses a shoe with a removable and interchangeable cushion and orthotic plate.
  • the cushion and orthotic plate are positioned and held in place by corresponding studs and apertures, or in the alternative by hook and loop material such as Velcro.
  • Gallegos does not alter the height of the heel or the tread on the sole.
  • U.S. Patent Application Publication No. US2009/0193684 to Diamond published on August 6, 2009, teaches a convertible shoe with removable and replaceable foot bed upper and sole portion with various height and style sole and heel portion.
  • the components are aligned by a series of corresponding prongs and recesses, and held in place by corresponding hook and loop material such as Velcro, along with a series of snap like fasteners on the periphery of the outsole.
  • Diamond discloses heels of differing heights and styles, but does use an insert placed between the insole and sole to alter the height of the shoe or the heel.
  • U.S. Pat. No. 7,246,453 to Kim, issued on July 24, 2007, teaches a bowling shoe with interchangeable soles. Apparently some bowlers want one of their shoes to slide a bit more than the other, and this invention allows them to do this.
  • the shoes consist of a separate depression in both the heel and the forefoot portion of the shoe. There is an alignment recess that runs roughly around the perimeter of the depression.
  • the interchangeable sole plates have a coupling protrusion that fits into the alignment recess to properly align the sole plate into the depression.
  • the sole plate fits entirely into the depression, and its outside perimeter of the sole plate is also within the depression. Because of the nature of bowling shoes, the sole plates are flat to correspond to the flat surface of the bowling lane. Because of this the attachment surfaces within the recess are also flat.
  • U.S. Pat. No. 8,307,571 to Ceylan discloses a ladies shoe that can be converted from a flat style shoe to a stiletto style high heel shoe.
  • the bottom of the top shoe is flat to create the sole of the flat shoe.
  • the shoe base has a flat top attachment surface with a recessed lip that mates with the flanges of the attachment plates to hold the shoe base to the top shoe to create a high heeled show.
  • Chaney is drawn to a shoe having interchangeable soles.
  • the shoe upper has a recessed cavity on the bottom that is defined by a sidewall that runs the entire perimeter of the shoe, and an interchangeable sole unit that fits within the recessed cavity.
  • There is hook and loop material inside the cavity that helps hold the sole unit in place, and a series of flaps which also help hold the sole unit within the recessed cavity.
  • the invention consists of a convertible shoe with an interchangeable sole.
  • the shoe is a men's dress shoe with a removable sole that can be replaced with a sole having "soft spike" golf cleats, to convert the shoe from a standard dress shoe to a golf shoe.
  • Other embodiments of the invention include a casual shoe that converts to a golf shoe, a sport style "tennis” shoe that converts to a golf shoe, and a sports style shoe with
  • the convertible shoe consists of a upper that holds the wearer's foot, and an
  • the underside of the upper has an attachment surface that mates with an attachment surface on the outsole to removably attach different outsoles. This is achieved by a unique paired top and bottom attachment of the two components. There are two main features that make this unique. First, the entire surface is contoured, which means that it is not flat, is curves from between the heel portion and the toe portion, but also at the toe kick. This means that the attachment components, specifically the mated hook and loop material and the paired offset ridge and channel, are in three dimensions and not just two dimensions as when the attachment
  • Another unique component of the present invention is that, in one embodiment, there are two paired ridges and channels, a heel end attachment and a toe end attachment.
  • the toe end attachment sits under the toe of the wearer's foot, and ends just behind where the ball of the foot sits in the shoe. This is the place where shoes are subject to the most bend, and consequently the place where most attachments come apart.
  • the flex grooves are located between the front (or toe) and rear (or heel) ridge and channel.
  • the flex grooves are just behind the ball of the wearer's foot. This is the spot on a shoe that is subject to the most bending as the wearer walks in the shoe.
  • the flex grooves allow the shoe components to bend, which reduces the bending in other parts of the shoe and therefore minimize the forces on the front and rear paired ridges and channels.
  • the present invention accomplishes this by means of the attachment mechanism which consists of the paired and mated protruding ridge and recessed channel, and the attachment material.
  • the perimeter ridge is on the underside of the upper component and the recessed channel is on the top side of the lower component.
  • the paired perimeter ridge and channel also protect the attachment material from dirt and other foreign objects when the components are attached, which will prevent the fouling of the attachment material and reduction of the attachment properties of the attachment material.
  • the combination of the paired ridge and channel and the contoured or three-dimensional attachment surfaces has proven so secure that in some cases is has been difficult to separate the components. This led to the creation of the additional element of a gripping surface on one of the components that allows the user to grip the component to pull them apart.
  • the gripping surface consists of a thumb recess in the rear of the outside perimeter of the upper. This allows the wearer to grip the rear of the outsole in one hand and the body of the upper in the other, and pull the two components apart.

  • shear forces This is known in the shoe making industry as “peel forces” because these forces can cause the various layers of a shoe to peel apart.
  • dynamic forces as the wearer walks in the shoe. Many people step first onto their heel, which creates forward forces along the X-axis that slides the various layers of a shoe against each other. All people walk differently, and many twist their foot slightly while walking to create twisting forces. There are also lateral forces on both the X and Z axis where the components of the shoe slide on each other. Many people also have a slight twisting motion from the ball of the foot to the toes as they step off of their trailing foot as they step forward. This causes torque forces on the X and Z axes, and near the front portion of the shoe. These various forces are known as shear forces. The combination of the shear and peel forces, and the fact that these are dynamic forces, makes it difficult to keep separate components of a shoe attached.
  • the geometry of the paired underside 40 and topside 50 attachment components allows the attached components to withstand all of these forces, and allows the outsole 30 to stay securely attached to the upper 20, until the wearer decides to separate the components and replace one style tread with another.
  • One of the main places that a shoe flexes during walking is in the area just behind the ball B of the foot. This is because most people roll onto their toes as they step forward. This causes the shoe to bend the most just behind the ball B of the foot.
  • the front part of the shoe, at and under the toes T bends a little, but in many cases the slight curve of the toe kick allows the shoe to simply roll without bending.
  • the heel portion h of the shoe is also not subject to significant bending forces, in part because the heel H of the foot F comes up in the opening of the housing 21 of the upper 20.
  • the flex grooves 49 on the upper and flex grooves 59 on the outsole 30 respectively, allowing the two components to bend easily at the point just under and behind the ball B of the foot.
  • the flex grooves 49 and 59 are cut into the material of the upper 20 and outsole 30 which allow the upper 20 and outsole 30 to both easily contract and expand, allowing both the upper 20 and outsole 30 to easily flex or bend in both directions, and to create a flex area on the upper and outsole.
  • Another unique feature is the contoured shape of the attachment between the upper 20 and the outsole 30. Since both the underside attachment surface 40 and topside attachment surface 50 are contoured to follow the curvature of the human foot, the attachment between the underside attachment surface 40 and top side attachment surface 50 is also contoured, and therefore when they are attached the mated attachment is non-planar, or not flat. It angles from the rear to the front or from the heel end h to the toe end t, and therefore can more easily withstand the planar sheer forces on the shoe. Specifically the heel end protruding ridge 41h runs from the flat portion of the heel end 40h through part but not all of the curved part of the arch portion 40a.
  • heel end recessed channel 51h runs along the flat portion of the heel end 50h through part but not all of the arch portion 50a. This is best seen in the side view of FIG 2. This means that both the heel end protruding ridge 41h and the heel end recessed channel 51h are on contoured, non-planar surfaces.
  • the paired attachment material 42 (42t & 42h) and 52 (52t & 52h) prevents the components from coming apart due to up and down or "peel" forces on the Y-axis.
  • the placement of the protruding ridge 41 (41t & 41h) within the recessed channel 51 (5 It & 51h) when the components are mated, is designed to account for all of the other shear forces and the X-axis & Z-axis. Since the paired ridge 41 and channel 51 runs just inside the perimeter of the components, it can withstand lateral and twisting forces, and thus ensure the components of the shoe can stay together.
  • contoured, or three dimensional non-uniform configuration allows the paired ridge 41 (41t & 41h) and channel 51 (5 It & 51h) to account for all of the various three dimensional and non-vertical shear forces that are present on the shoe 100.
