  • Patent number: 6061928
    Abstract: An improved cushioning assembly is provided in which separate, independent cushioning elements are loaded into a pocket of the sole assembly of the shoe. By providing separate and independent cushioning elements, greater variation of the performance of various regions of the shoe can be provided, by utilizing cushioning elements having variations in one or more of their size, shape, orientation, material properties, and amount of precompression. As a result, different regions of the shoe can be better tailored for a particular activity or a particular user. In addition, by providing separate independent cushioning elements, the cushioning elements can be more closely packed as compared with, for example, prior cushioning elements formed as contiguous sheets. With the enhanced ability to more closely pack the cushioning elements, the cushioning elements can better transfer forces laterally, to better absorb and dissipate the forces.

  • Patent number: 6004662
    Abstract: A highly flexible composite material having a flexible matrix containing a phase change thermal storage material. The composite material can be made to heat or cool the body or to act as a thermal buffer to protect the wearer from changing environmental conditions. The composite may also include an external thermal insulation layer and/or an internal thermal control layer to regulate the rate of heat exchange between the composite and the skin of the wearer. Other embodiments of the PCM composite also provide 1) a path for evaporation or direct absorption of perspiration from the skin of the wearer for improved comfort and thermal control, 2) heat conductive pathways within the material for thermal equalization, 3) surface treatments for improved absorption or rejection of heat by the material, and 4) means for quickly regenerating the thermal storage capacity for reuse of the material. Applications of the composite materials are also described which take advantage of the composite's thermal characteristics.

  • Patent number: 5992054
    Abstract: A process which serves to seal and waterproof the outsole-side end area of a waterproof shoe shaft and/or to pad the outsole-side end of a shoe by putting a liquid, curable, filling material into the space between the insole and outsole is described. The outsole is provided with an input opening for putting in the filling material. The outsole is adhered to the shaft only in a circumferential area and in such a way that the outsole-side end area of the shaft remains unadhered. The liquid filling material is put in through the input opening, between the insole and the outsole, from where it flows into the outsole-side end area of the shaft due to its good flowability. The liquid material contains polyurethane precursor ingredients which react to form a foam polyurethane.

  • Patent number: 5890248
    Abstract: An item of footwear such as a shoe comprises an outer sole which may include an intermediate mid sole, an upper having an insole with a cavity between the outer sole or mid sole. The cavity receives injected into it cushioning resilient foam material which may extend into a heal portion of or to the outer sole of a multi-layer sole and heel unit. In the method of manufacture and after the assembly of the shoe with the empty cavity, the resilient material is subsequently injected into the cavity e.g. through a small bore in the outer sole or elsewhere. Vent hole enable air to escape from the cavity to ensure full and intimate filling of the cavity with the foam material. The upper may be retained on a last during injection to maintain a desired profile of the insole. Quantity and/or pressure of the injected material may be varied for obtaining different degrees of cushioning.

  • Patent number: 5367791
    Abstract: A shoe sole insert has foam-filled independently compressible regions that extend through a midsole and beyond an outsole bottom surface so a particular region, when it strikes a traversed surface, is compressed vertically and expands horizontally against the midsole. In one embodiment, five groups of such regions are beneath the metatarsal bones and proximal phalanges. In a second embodiment, two transversely extending regions are beneath forward and rearward portions of the metatarsals. The rearward transverse region has a ridge that is farther from the outsole bottom face than a ridge of the forward transverse region. In another aspect, an array of regions below the tarsal and calcaneus bones is arranged so a region at the very rear of the heel compresses vertically to a greater extent than a lateral side region in response to the same striking force, so pronation tends to be corrected.

    Abstract: A cement construction shoe is provided having a soft, flexible insole and a cushioned outsole. In manufacturing the shoe, the insole is temporarily stiffened by a relatively firm member to which it is bonded by means of a wax. This enables the insole to withstand the normal lasting procedure. The outsole is provided with a cavity for receiving a cushion therein. The shoe upper is attached to the outsole such that the insole overlies the cushion. Once the shoe is completed, the wax bond between the insole and its stiffener may be heated to allow the separation and removal of the latter.

  • Patent number: 4517308
    Abstract: The aim of the invention was to find a method of producing a sorptive body, to be used especially with objectives such as the elimination of odors and air freshening. In the invented process a granular or powdered solid component consisting of a sorptive material, e.g. active carbon, or a compound containing such a material, is mixed with a binding agent, by which it is generally fixed to a carrier substance. The essence of the invention is that at least part of the finely-ground solid component is mixed with a liquid sorbate; only then it is combined with the dissolved binding agent. In a subsequent operation heat is applied to the mixture, thereby expelling the sorbate. The heat causes pores and capillaries to form within the binding agent, thus enabling air to enter into the sorptive substances deposited in the binding agent and so effecting an increase in the active area of the surface of the body.
