BACKGROUND OF THE INVENTION

A. Field of the Invention
The present invention relates to a special shoe insert designed to be positioned within the interior of various types of athletic shoes that would prevent the front area or toe section from creasing.
Typically an athletic shoe forms a crease on the front of the show just above where the toes are situated. This crease detracts from the overall appearance and diminishes the useful life of the shoe.

DETAILED DESCRIPTION OF THE EMBODIMENT

Detailed reference will now be made to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Referring to FIGS. 1-8, a shoe insert 10 involves an outer shell 15 that is made of a rigid material comprising wood, metal, or a hard plastic. The shoe insert 10 involves a semi-rigid inner shell 16. The shoe insert 10 is used by placing the shoe insert 10 into a shoe 20.
Reference will now be made to the alternative embodiments of the present invention, depicted in FIG. 8. A second embodiment 30 provides a fragmented less-rigid application. The second embodiment 30 involves the semi-rigid inner shell 16 and a fragmented less-rigid outer shell 31. A third embodiment 40 provides a fragmented less-rigid application. The third embodiment 40 involves the semi-rigid inner shell 16 and a second fragmented less-rigid outer shell 41. A fourth embodiment 50 provides a slotted design that is appropriate for a less rigid application. The fourth embodiment 50 involves the semi-rigid inner shell 16 and a slotted outer shell 51.
Reference will now be made to a spring-loaded 60 embodiment depicted in FIG. 6. The spring-loaded embodiment 60 involves the semi-rigid inner shell 16 and a spring-loaded outer shell 61. The spring-loaded outer shell 61 has a plurality of springs 62 located about its middle.

Claims
