Abstract
A molded athletic boot, a reinforcing insert assembly for a molded athletic boot and a method of making the boot are described. A cloth-like insert is mounted on a last and a mold is then closed about the last. A castable material, such as polyurethane is injected into the mold so that it impregnates and encapsulates the insert prior to solidifying to form an athletic boot having great tensile strength and rigidity. The described insert assembly comprises a porous, elastic, sock-like element which fits over the last. A layer of a woven or knitted polyamide and a layer of a nonwoven polyamide are secured inside the sock-like element at selected locations.
Claims25
An athletic boot comprising a molded outer shell shaped to encase a human foot, and a porous, cloth-like insert impregnated and encapsulated by the material of said outer shell and interlocked therewith, said insert having a higher elastic modulus than said outer shell.
An insert assembly for use in the manufacture of an athletic boot, said insert assembly comprising an outer sock-shaped insert element of flexible, elastic and highly porous material capable of being fitted loosely but securely over a last, said insert assembly further comprising a reinforcing insert element of at least one layer of cloth-like material fastened to said outer insert element.
A method of making an athletic boot, said method comprising the steps of mounting a cloth-like, porous insert assembly upon a foot shaped last, positioning a mold about the last and then injecting a castable rubber-like material into the mold to fill the space between the mold and the last and simultaneously to impregnate and surround the insert to form a strong unitary shell shaped to encase a human foot.
