Abstract: A shoe, in particular a ladies high-heeled shoe, has a heel tap (3) fastened by means of a pin (4) to the heel (1), the pin having a head (13) which passes, secured against rotation, through a hole in the heel tap. The pin extends, with an expansion seat, within an expansion sleeve (6) of the heel and has a longitudinal bore (17) of circular cylindrical shape into which an expansion nail is driven. The expansion nail (18) has a non-circular cross section.

Abstract: An antiwear and nonskid protective element for a shoe heel, which comprises an outside first part in which a through opening is made the surface of the cross section of which is greater on the side in contact with the heel of the shoe than on the side of its free end; and a second part comprising a head, whose shape and dimensions correspond approximately to those of said opening, and a rod provided with a rigid inside reinforcement, the rod being able to be driven with force into a hole made in the heel for the fastening of the element. Thus, an effective and reliable fastening of the element to the free end of the heel.

Abstract: A heel lift comprises an elongated body portion having a blunt or pointed upper end for insertion into a shoe heel, a lock washer or ring member with inwardly directed projections fitted and locked about the body portion and a head portion connected to the lower end of the body portion, the head portion having a slot and an annular undercut which cooperate to form passages within the head portion through which a molding material forming a wearing portion can flow when the lock washer and the head portion are coated with the molding material whereby the wearing portion is firmly bonded to the head portion.

Abstract: A urethane prepolymer repair system is provided by an isocyanate-terminated polytetramethylene ether glycol prepolymer of about 3,500-10,500 molecular weight that cures to an elastomer upon exposure to atmospheric moisture and is packaged in a container capable of repeatedly dispensing the prepolymer with minimal exposure to ambient air, such as a collapsible tube or caulking gun cartridge. The repair system is used to build up worn down soles and heels of footwear, repair separations of soles and heels from shoe tops, and hundreds of other uses.

Abstract: In a shoe construction, effective chemical bonding rather than nailing of a lower rubber heel to an inner heel base is enabled by the chemical composition and surface conditioning of the latter. The chemical composition is characterized by a mixture of a polyethylene, an ethylene vinyl copolymer, a filler, and a dessicant in particular proportions. The surface conditioning is characterized by an oxidizing flame treatment.
