Footwear sole component

Footwear sole

A sole component having a base, a toe cover and an integral line of articulation permitting the toe cover to be molded in an 'open' position and moved into a 'closed' position during assembly on the article of footwear. The line of articulation may include a line of reduced thickness extending laterally across the sole. The line of articulation may also include breaks defined in the sidewall of the sole in alignment with the line of reduced thickness. The present invention also provides a method of forming a sole component generally including the steps of providing a mold having bottom and top mold parts shaped to cooperatively define a mold cavity in the shape of a sole component having a toe cover joined to a base along a line of articulation, closing the mold parts, injecting a sole forming material into the cavity, removing the sole component and moving the toe cover about the line of articulation into a closed configuration for use.

Sole component for an article of footwear and method for making same

A footwear sole includes shock absorbing elements that extend from upper and lower plates. In one embodiment, the shock absorbing elements include a bridge defining a plurality of receptacles extending from the lower plate and a plurality of protrusions extending from the upper plate. Each protrusion is associated with one receptacle, and a portion of each protrusion extends into the receptacle.

Shock absorbing footwear construction

A method of manufacturing an article of footwear having a direct attach sole component includes providing an upper and a receptacle shell that defines a receptacle adapted to receive a cushion insert. A molding insert is placed into the receptacle, and the upper is joined with the receptacle shell. A mold is closed about the receptacle shell and at least a portion of the upper to form a mold cavity corresponding to the direct attach sole component. Material is introduced into the mold cavity to form the direct attach sole component. The mold insert protects the shell from deformation during the molding process. The mold insert is removed and replaced with a cushioning insert after the molding process. The footwear can optionally include a partially transparent shell that supports a sole component that receives a cushion insert, such that the cushion insert and/or sole component are visible through the shell.

Method of manufacturing an article of footwear having a direct attach sole component

An impact absorbing material for a footwear article includes a first sheet having a plurality of projections for dispersing the force of an impact and a second sheet, having a lower durometer than the first sheet, that is bonded to the first sheet for absorbing the force from the projections. The projections are arranged on the first sheet such that nonlinear gaps are formed between adjacent pairs of projections. The impact absorbing material may be positioned between an upper and an inner liner of the footwear article and may be selectively positioned on the footwear article to protect an area on the wearer that is vulnerable to impact, such as the wearer's feet, ankles, heels or calves.
