Insert for Supporting and Aerating a Shoe Structure

Abstract

A shoe insert is configured as a single component with a specifically-configured shape that provides internal shoe structural support while enhancing airflow within the shoe. The shoe insert is comprised of a rigid structure, such as plastic, that engages with the inner and outer sides of the shoe to provide sufficient support. The shoe insert's inner and outer sides, which engage with the shoe's inner and outer sides, have a grip portion with an upper opening substantially positioned at the shoe's ankle opening. This upper opening enables air to flow therethrough and provide breath to the shoe's interior cavity. Airflow holes spread sporadically throughout the shoe insert's body enables air to flow through the shoe insert and engage the shoe to provide breathability, thereby preventing moisture, mold, and stench.

What is claimed: 
     
         1 . A single-piece footwear insert, comprising:
 a grip portion, wherein the grip portion is a highest level of the footwear insert;   outer and inner slopes that extend from the grip portion, wherein the outer and inner slopes are opposite edges of the footwear insert that extend in a gradual downward direction from the grip portion, and wherein the outer and inner slopes are positioned at a lower height to the grip portion;   outer and inner support sides that respectively extend from the outer and inner slope, wherein the outer and inner support sides are edges of the footwear insert that gradually meet in a concentric configuration so that the outer and inner support sides at least partially engage with an interior of a piece of footwear in which the footwear insert is placed, and wherein the outer and inner support sides form a different plane relative to the outer and inner slopes; and   wherein the footwear insert is a single unitary layer of material on which is the grip portion, outer and inner slopes, and outer and inner support sides, and   
     
     
         2 . The shoe insert of  claim 1 , wherein the grip portion forms an obtuse angle, and an upper opening is positioned on the grip portion. 
     
     
         3 . The shoe insert of  claim 1 , wherein the at least one airflow hole are concentrated on the inner portion of the shoe insert. 
     
     
         4 . The shoe insert of  claim 1 , wherein the at least one airflow hole is indented from an upper surface of the shoe insert to a bottom surface, and the at least one airflow perimeter extends beyond a bottom surface of the shoe insert. 
     
     
         5 . The shoe insert of  claim 1 , wherein an end of the shoe insert's inner and outer support sides are substantially vertical and consistently vertical from the inner support side to the upper support side. 
     
     
         6 . The shoe insert of  claim 1 . wherein a front-most region of the shoe insert has a greater slope than its sides to facilitate insertion and removal of the shoe insert.
