2. Description of the Related ArtFootwear comes in many different types, styles, shapes, and colors. Frequently, the consumer wants to coordinate the footwear with the rest of the clothing outfit. This can result in the consumer purchasing numerous pairs of shoes to go along with the consumer's many outfits for various occasions.
Certain shoe features may be more desirable, more functional, or more comfortable for certain activities and occasions. For example, there are times when it is desirable to quickly and easily remove and put on your shoe while at other times it is desirable to have shoes that remain snugly secured to your feet. Additionally or alternatively, there are times when you want your shoes to be lightweight and other times when you want your shoes to provide a soft, cushioned feel.
Oftentimes, one component of the footwear, for example the sole, receives greater wear than other components which results in the worn out footwear being discarded prematurely. This could be avoided if one or more of the footwear components could be replaceable or interchangeable to prolong the useful life of the footwear.
Additionally, the aesthetic look of footwear is affected by the type of securement to the foot, for example, shoe laces, stretchable slip on, etc. Also, the aesthetic look of footwear is affected by straps or tags attached to the upper portion of the footwear.
There have been several attempts at providing footwear with some interchangeability and/or customization. A few of them are:
