For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in FIGS. 1-9. However, it is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

As shown in FIGS. 1-7, the present invention is a removable form-fitted outsole cover 10 comprised of a single piece of elastic material especially adapted for attachment to the bottom or outsole 16 of an article of footwear 12. The article of footwear 12, as is known in the art, has a finished upper 14 and a finished outsole 16, as well as a toe 19 and heel 21. The upper 14 is attached to the outsole 16 at an intersection 18 of the upper 14 to the outsole 16, preferably by beaded stitching 13, to define a rim 17 about an outer perimeter of the outsole 16 of the boot 12. However, methods of attachment of the upper 14 to the outsole 16 other than beaded stitching 13, such as an adhesive, may be used. In accordance with the present invention, the rim 17 of the outsole 16 has a circumference greater than the circumference of the intersection 18. While the article of footwear 12 shown in the present specification is configured as a boot, it should be understood that other types and styles of footwear may advantageously enjoy the present invention, including, but not limited to, dress shoes, casual shoes, athletic shoes, work boots, dress boots, sneakers, and hiking boots and shoes. It should also be noted that articles of footwear having outsoles provided with more rugged treads, such as those used in outdoor activities, and defined heels may benefit from the present invention.

Significantly, the outsole cover 10 of the present invention is designed and fitted to attach to a specific article of footwear style and size, regardless of the specific manufacturer. As is known in the art, footwear 12 designs are available in a wide array of styles and sizes, wherein the finished upper 14 and the outsole 16 are modified to obtain a particular functionality and fashion appearance. By designing and fitting the outsole cover 10 of the present invention to attach to a specific style and size of an article of footwear 12, a defined and predetermined style and fashion statement can be uniquely obtained, while also providing protection to the outsole 16 of the boot 12. Further, the outsole cover 10 offers an inexpensive way to markedly alter the appearance of the footwear 12 in a manner desired by the user. In addition, the outsole cover 10 provides an inexpensive method of concealing an otherwise worn or disfigured outsole 16.

The outsole cover 10 is comprised of a sole 20 and an outer band 22 attached to the outer periphery of the sole 20. The outer band 22 is shaped and sized to be adapted for attachment to and conformance with the specific style and size of rim 17 of the outsole 16 of the article of footwear 12. The outer band 22 of the outsole cover 10 comprises a rim portion 24 and a lip portion 26. The circumference of the rim portion 24 is greater than the circumference of the lip portion 26. In turn, the circumference of the lip portion 26 is less than the circumference of the rim 17. The outer band 22 is thus specifically shaped and sized to be adapted for attachment to and conformance with the rim 17 of the outsole 16 of the boot 12 to cover the outsole 16 of the boot 12. Preferably, the outsole cover 10 covers the entire outsole 16 of the boot 12, up to and including the intersection 18 where the upper 14 meets the outsole 16, as shown.

The outsole cover 10 preferably is fabricated from an integrated single piece of elastic material and utilizes an injected molding construction. Of course, other manufacturing techniques may be employed, such as compression molding and vacuum forming. Preferably, the elastic material is 100% elastic and comprises natural rubber, silicone rubber, chlorosulfonated polyethylene synthetic rubber (CSM) (“hypalon”) or blends thereof. These materials are desirable as exhibiting properties important to the practice of the invention, including flexibility and resistance to ozone, sunlight, and oxidation. These materials also provide superior weather ability and resistance to oil, even at high temperatures, as well as resistance to cracking and abrasion from weather, heat, and chemical exposure. Such materials also provide low water absorption.

Moreover, the outsole cover 10 should be pliable in order to be attached to the outsole 16 of the specific style/size of the article of footwear 12, such that the user may readily attach and remove the outsole cover 10 to and from the article of footwear 12, as well as to confidently and safely walk about with the outsole cover 10 securely attached to the article of footwear 12. Thus, the outsole cover 12 covers the entire outsole 16 of the article of footwear 12, preferably up to and including the intersection 18 of the upper 14 to the outsole 16.

In operation, the toe 19 of the article of footwear 12 is inserted into the toebox 30 of the outsole cover 10 by stretching the lip portion 26 of the outer band 22 near the toebox 30 to allow insertion of the rim 17 of the outsole 16 into the outsole cover 10, as best shown in FIG. 3. Once the toe 19 of the article of footwear 12 has been snuggly inserted into toebox 30, the lip portion 26 near the heel portion 32 of the outsole cover 10 is stretched to receive the heel 21 of the article of footwear 12. Once the heel 21 has been inserted into the heel portion 32, the lip portion 26 near the heel portion 32 is released, whereupon the outer band 22 is snuggly attached to and conforms with the rim 24 of the outsole 16 of the article of footwear 16 to preferably cover the entire outsole 16 of the article of footwear 12 up to and including the intersection 18 of the upper 14 to the outsole 16. Of course, the operation described above can instead begin as well with the heel 21 and heel portion 32. Removal of the outsole cover 10 from the article of footwear 12 is simply the foregoing operation in reverse.

It should be appreciated that as well as providing protection to the outsole 16 of the article of footwear 12, the removable form-fitted outsole cover 10 may be provided with a wide variety of style and fashion features that may be used to augment the style and fashion aspects of the article of footwear 12. For instance, the lip portion 26 of the outer band 22 may be given a first texture or surface treatment and the rim portion 24 of the outer band 22 may be given a second, different texture to create contrast and interest. Different colors may also be provided on the rim portion 26 of the outer band 22. Indeed, colors, patterns, and lines along the outer band 26 may be used to generate interesting and desirable styles and appearances.

Also, the lower portion 27 of the sole 20 of the outsole cover 10 may be provided with a wide variety of the tread patterns and designs, such as herringbone, swirls, and cross-hatching, as well as more rugged treads designed for outdoor use.

An alternative embodiment is shown in FIGS. 8 and 9, where a dual-sided die-cut adhesive sheet 42, cut to conform precisely to either the inner sole 34 of the outsole cover or the inner rim wall 36 of the outer band 22, is provided to further secure the outsole cover 10 to the footwear 12. Preferably, the double-coated, double-sided adhesive sheet of medium tact is Model No, 3M6450-ND, 9786 Tape Dbl Coated, in sheets 8.5 inch by 8.5 inch, manufactured by 3M and fabricated from acrylic, 300MP poly-coated draft liner. The dual-sided die-cut adhesive sheet may be between 0.0097 inch and 0.0042 inch, and is preferably 0.008 inch in thickness for appropriate comfort the user. Preferably, the sheet 42 is attached to at least a portion of at least one of the inner rim wall 36 and the inner sole 34, and, more preferably, to both.

It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
