Benefits of technology

[0008] It is an object of the present invention to provide a shoe with an improved sole having slip resistance and improved traction.
[0009] It is another object of the present invention to provide an improved method of securement between midsole and outsole elements.
[0010] Yet another object of the present invention is to provide an improved sole for footwear having at least one element therein that has slip resistance, wherein the sole has enhanced integrity.
[0011] Still further, another object of the present invention is to provide an improved method for producing a sole for footwear having at least one element forming a part thereof with enhanced sole integrity and slip resistance.

Problems solved by technology

While such materials exhibit good resilience and shock absorption properties, their shortcomings include poor resistance to wear.
However, over time, adhesive materials begin to fail.
In addition, such materials may make the manufacturing process and resulting product more costly.

Abstract

Footwear with an improved sole, and an improved sole and a method for manufacturing the same are provided. The improved sole includes at least one pod secured in situ to a molded outsole. Each pod includes a ground-engaging end and an upper end having an outwardly extending flange proximate thereto. In the method for manufacture of the sole, the outsole is secured to the pods in situ. The outsole and pods are formed from different materials and are secured in situ during formation of the outsole, with each pod placed in a mold cavity section and the flange being encapsulated by the moldable outsole material.

Description

FIELD OF THE INVENTION [0001] The present invention relates to footwear with an improved sole. In addition, the present invention relates to an improved sole and a method for making the improved sole. BACKGROUND OF THE INVENTION [0002] Footwear typically incorporates elements designed to achieve a balance between comfort, appearance, durability, and traction properties. Slip resistance and traction are particularly important in the design of footwear. Therefore, sole components are essential to the balance of elements for a shoe. [0003] Shoes are typically made from an upper with a sole system attached to the upper. The sole system includes an insole, a midsole, and an outsole. [0004] Midsoles, which provide a cushioning layer between the outsole and upper, are preferably formed from materials that absorb shock while providing stability. Such materials may often include ethylene vinyl acetate (EVA), polyurethane, thermoplastic polyurethane (TPU), or combinations thereof. While such ...
