Interchangeable orthopedic footwear
An article of footwear includes an outer sole having a bottom walking surface and an opposed top surface, an upper member and a zipper member connected to the outer sole and to the upper member for releasably securing the upper member to the outer sole. An orthopedic appliance is received within a cavity that is disposed within the top surface of the outer sole.
The present invention relates, in general, to footwear and, more particularly, this invention relates to footwear having interchangeable outer sole and upper members and, yet more particularly, the instant invention relates to orthopedic footwear having interchangeable outer sole and upper members and an orthopedic appliance received in such outer sole.
BACKGROUND OF THE INVENTIONAs is generally well known, customization of an outer sole of the footwear to receive an orthopedic appliance in order to correct particular foot and ankle conditions of a wearer is a time consuming effort which is performed by a licensed medical practitioner. Therefore, the orthopedic footwear is associated with considerable expense due to such customization. The wearer of such customized orthopedic footwear is disadvantaged due of such expense and often forgoes the aesthetic considerations for the sake of comfort by wearing the same orthopedic footwear in different conditions. The presently available modular articles of orthopedic footwear fail to simply and easily alleviate the disadvantage experienced by the wearer of the orthopedic footwear.
Therefore, there is a need for an improved article of orthopedic footwear which enables the wearer to simply and easily modify the styles of such footwear by reusing the same outer sole.
SUMMARY OF THE INVENTIONAccording to one embodiment, the invention provides an article of footwear which includes an outer sole having a bottom walking surface and an opposed top surface. There is an upper member and a zipper member connected to the outer sole and to the upper member for releasably securing the upper member to the outer sole.
According to another embodiment of the invention, there is provided an article of footwear which includes an outer sole having a bottom walking surface and an opposed top surface. There is an upper member and a zipper member connected to the outer sole and to the upper member for releasably securing the upper member to the outer sole. An orthopedic appliance is received within a cavity which is disposed within the top surface of the outer sole.
OBJECTS OF THE INVENTIONIt is, therefore, one of the primary objects of the present invention to provide an article of footwear.
Another object of the present invention is to provide an article of footwear which has a modular construction.
Yet another object of the present invention is to provide an article of footwear which has a modular construction enabling the wearer to interchange various styles of outer soles and upper members.
A further object of the present invention is to provide an article of footwear which has a modular construction enabling the wearer to simply and easily interchange the outer sole and the upper member.
Yet a further object of the present invention is to provide an article of footwear which has a modular construction and incorporates an orthopedic appliance.
In addition to the several objects and advantages of the present invention which have been described with some degree of specificity above, various other objects and advantages of the invention will become more readily apparent to those persons who are skilled in the relevant art, particularly, when such description is taken in conjunction with the attached drawing Figures and with the appended claims.
