    Abstract: A method for manufacturing a one-piece shoe shell of a skate with different widths having acts of forming a shoe shell with a rudimentary mold assembly, ejecting the shoe shell from the rudimentary mold assembly and adjusting a width of the sole of the shoe shell before the shoe shell hardens. The sole of the shoe shell has at least one adjusting portion to allow the sole to expand or be compressed. With the acts, each size of the shoe shell needs only one rudimentary mold assembly that has complex structure and high cost to substantially form a basic shape of the shoe shell and multiple shaping molds of different widths that have simple structure and low cost are prepared to further adjust widths of the shoe shell. Consequently, total cost for manufacturing the shoe shell with different widths is effectively lowered.

    Abstract: A custom orthotic sandal is formed to a biomechanically corrected shape of a user. To obtain the proper shape for the sandal, a negative cast is taken of the user's foot. A positive impression cast is then formed from the negative cast. The positive impression cast is then modified to correct for biomechanical abnormalities of the user's foot. The custom orthotic sandal is formed by adhering a moldable material on the sole of the sandal. The positive impression cast is then pressed on the moldable material to form the proper shape. The moldable material is then set and the sole is assembled into the sandal.

  • Patent number: 6438873
    Abstract: An athletic shoe including a upper, a support member or “chassis” attached to the underside of the upper, and sole elements attached to the bottom of the support member. The support member provides support for the foot, and thereby permits use of spaced apart sole elements rather than a full midsole and a full outsole. In addition, the support member can be tailored to provide the optimum stiffness for a particular activity or user.

  • Patent number: 6412194
    Abstract: A pad for supporting a portion of the human body is made of two substantially non-stretchable or non-elastic layers that are joined together along a peripheral edge and then are joined together in local regions to form individual capsules in the pad. The layers are “quilted” in the areas defined by the capsules to control where and how much the pad can bulge. The pad is filled with a wax material that is plastic but does not flow readily. By repeated applications of loads the wax will flow or migrate slowly to change the configuration of the wax to conform to and support the surface contacting the pad.

  • Publication number: 20020050080
    Abstract: A contoured, pre-molded and heat moldable orthotic device (1), ideally of about three-quarters of the length of the boot or shoe in which it is to be worn, has a 4° rear foot varus angle or wedge with an integrally-formed heel cup (3), a longitudinally-extending “raise” (4), a metatarsal “raise” (5) and a spongy shock-absorbing insert (6). The device is intended to be purchase “off-the-shelf”, for the relief of generalized and relatively minor common biomechanical foot problems.

  • Patent number: 6315786
    Abstract: An orthotic device for treating heel pain associated with Plantar Fasciitis is disclosed, comprised of a flexible heel cup shoe insert with a bar-shaped member extending laterally across the bottom sole portion of the device and located under the heel-arch connection of a person's foot when worn by the person in order to apply continuous accupressure to the calcaneus-midtarsal connection area and thus alleviate pain.

  • Patent number: 6247250
    Abstract: A shoe insert includes a support layer having a bottom surface and a top surface opposing the bottom surface. The shoe insert further includes a cushion layer fixedly superposed onto the top surface of the support layer. The bottom surface includes a generally planar distal portion, a proximal portion and a medial portion interconnecting the distal portion and the proximal portion. The distal portion cushions the toes and the ball of the foot. The proximal portion supports the heel of the foot and has a centrally disposed depression concave and a generally planar border located posteriorly with respect to the centrally disposed concave depression. The centrally disposed concave depression and border together produce a medial and lateral wedging effect against the heel of the foot. The medial portion supports the mid-region of the foot.

  • Patent number: 6219942
    Abstract: An article of footwear comprises a shoe in which the upper and base define a first total internal volume; molding of a standard inner sole made of a material which may be plastically thermoformed using a form, the inner sole having a second volume less than the first volume and, when inserted in a shoe, leaving a free volume, smaller than the total volume, inside the shoe; insertion of the standard inner sole in the shoe and fixing in place, so as to create a shoe-inner sole assembly in which, between the base and standard inner sole there is at least one space with an empty volume substantially corresponding to the difference between the first volume and the second volume; heating of the shoe-inner sole assembly made in this way to the preset temperature necessary for the thermoforming of the inner sole; insertion of a foot in the shoe, so as to shape the standard inner sole in the areas around the space according to the features of the sole of the foot.

  • Patent number: 6195917
    Abstract: An insole insert for application into a shoe, and which is formed as a laminar material of various layers of paper, polymer, stranded thermoplastic or thermosetting material, foams of select consistencies and texture, in addition to a felt or microfiber type of upper layer, to add to the cushioning and softness of the insert, when applied. The insert, when subjected to heat and pressure, particularly pressure applied by the foot, conforms to the contours of the foot, and sustains such, even after prolonged usage after application into a shoe.

  • Patent number: 6098315
    Abstract: An insert for a shoe comprises a pouch having a moldable, thixotropic material and a shell having a catalyst. The shell is capable of being ruptured by massaging the pouch to allow the catalyst to be released from the shell and mixed with the material. A pressure sensitive adhesive is on the bottom of the pouch to secure it to the inner sole of a shoe, and a nylon layer is on the top of the pouch to absorb moisture and provide an aesthetic appearance. In use, the pouch is massaged to mix the catalyst and moldable material and is then placed in a shoe. The user places a foot in the shoe and applies a light weight to the foot so that the pouch assumes the shape of the foot bottom and fills that space between the foot and the shoe. Then, the foot is removed to allow the material to cure. When the material is cured the insert prevents excessive collapse of the foot.

  • Patent number: 6026595
    Abstract: A new method of making custom fitted products and products made by such a method for improving the fit and comfort of such products. The invention includes incorporating a hollow, sealed envelope into an apparatus, injecting a hardenable, liquid gel-catalyst mixture into the envelope through an inlet, and using a portion of a persons body to apply pressure to the envelope and allowing the mixture to harden while the pressure is being applied. The initially liquid mixture will conform to the shape of the body part which is applying the pressure, and once hardened will provide a product which is specifically shaped to the individual's body part. The product could be a shoe, a safety helmet, protective padding for various parts of the body, handles on tools and implements, and the like.
