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.
