## Background
RELATED APPLICATION
This application claims the benefits of U.S. Provisional Patent Application No. 62/158,773 filed on May 8, 2015.


FIELD OF THE INVENTION
The present invention relates in general to footwear and more particularly to shoes with interchangeable covers.
BACKGROUND OF THE INVENTION
A shoe with interchangeable covers allows one to instantaneously change the look of the shoe. This feature would enable the individual to have numerous pairs of shoes for the price of one. One can match the shoe to a particular outfit using a style or a color that best matches the outfit. Therefore, there would be no need to purchase new pairs of shoes to match different outfits, thus providing significant savings. In addition, shoes occupy precious storage space in closets and the like. Whereas, different covers of an interchangeable shoe can all be stored in a much smaller volume. Storage space becomes more important when packing for a travel. It is difficult to fit several pairs of shoes in a suitcase, yet many travelers, especially business travelers, may need to have several pair of shoes for different events and occasions during their travel. Shoes with interchangeable covers allow the traveler to pack several different colors and styles of a shoe with carrying only one shoe base.
Shoes with interchangeable covers are known in the prior art. Shoes having a removable cover secured to the original shoe by hook and loop fastener have been disclosed. These covers provide a second layer to the shoe and cover the entire shoe and the user's feet would heat up and be uncomfortable.
Another disadvantage of these covers is that they could easily loosen and the cover would disengage from the shoe. Most of the Prior arts propose using a stretchable material for shoe cover. These materials are not a suitable covers. Additionally in some cases adhesive is used to secure the cover on original shoe which could ruin the original shoe.
Another disadvantage of the shoe covers disclosed in prior art is the securement means which are insufficient and the shoe cover could slip off the shoe during the use. In most of the shoe covers disclosed before, the cover changes only the front portion of the shoe leaving the back portion in original color and style.
The present invention discloses a shoe with interchangeable covers in which the front part and back part of the shoe can be easily and securely changed and provide different styles and colors as long as it keeps the original shape of the shoe without any slipping.
SUMMARY OF THE INVENTION
The present invention is an interchangeable shoe with transition insole that comprises of an insole and a shoe base, wherein the insole is removably secured to the shoe base by one or more fasteners, such as a snap or hook and loop fasteners. The shoe base and the insole each comprise of a toe end opposing a heel end, wherein the heel ends are removably secured to one another so as to allow one or more front straps to be disposed there between. The front strap is configured as a loop.
The toe ends of the insole and shoe base are secured together so as to prevent the front strap from detaching from the shoe. The interchangeable shoe further comprises of one or more heel straps adapted to removably secure a user's foot to the device. The heel strap is disposed around the insole and the shoe base, wherein it is removably secured to the bottom surface of the shoe base by one or more fasteners, such as a snap.
In another embodiment of the present invention, the heel strap is secured on the shoe base by a clamp mounted on the shoe base. The clamp allows the heel strap to be disposed there between to hold and secure the heel strap in place and prevent of any movement. The heel strap adapted to removably secure a user's foot to the shoe. The toe end of the insole is secured to the toe end of the shoe base by any suitable fastener, such as stitching.
In operation, the heel end of the insole is separated from the heel end of the shoe base, wherein the front strap is placed there between and positioned towards the toe end of the shoe in order to removably secure a foot thereto. The heel strap is then disposed in the clamp to removably secure the heel strap there in. The heel ends of the insole and shoe base are then secured to one another, whereby the insole of the shoe will completely cover the clamp and the heel strap and provide a comfortable fit.
It is therefore an object of the present invention to provide an interchangeable shoe covers that can be easily and quickly change the appearance of the shoe.
It is another object of the present invention to provide a simple means for quickly and firmly secure an interchangeable member to a shoe with simple and effective elements which do not affect the appearance or comfort of the shoe.
It is another object of the present invention that shoes which do not fit properly can be transformed into shoes that can be worn at any time and for any occasion and are great for those who find it hard to purchase the correct size shoes.
Other objects, features, and advantages of the present invention will be readily appreciated from the following description. The description makes reference to the accompanying drawings, which are provided for illustration of the preferred embodiment.
