SHOE SYSTEM WITH INTERCHANGEABLE UPPER SHOE PART

The present invention relates to a shoe system, comprising a sole and an interchangeable upper shoe part for receiving a foot of a user, wherein the sole and the upper shoe part are provided with cooperating fastening means for a releasable fastening.

Several shoe systems with interchangeable upper shoe parts are known in the relevant art. The shoe system according to the preamble is for instance described in US2013/0091734. The known shoe system provides a shoe sole with a side-to-side slot for receiving a removable strap, with the strap having ends that may be joined so as to form a shoe upper shoe part. The known shoe system has the advantage that it allows a user easy coordination with a variety of his or her clothing. The known shoe system uses different, rather straight forward fastening means known per se in the relevant art to join the outer ends of the strap. Examples of fastening means include Velcro, snap fits and loops. Consequently the resulting appearance of the known shoe system can be described as rather conventional.

It is the object of the present invention to provide a shoe system according to the preamble having a unique fashionable appearance.

The shoe system according to the present invention is thereto characterized in that the fastening means comprise a button closure, comprising a button, an attaching member for attaching the button to the sole and a decorative member, wherein the button has an upper side that is arranged to releasably receive the decorative member.

Although button systems as described in the characterizing part of the main claim are known per se in the art of clothing, they have never before been proposed for use as a closure system on shoes. This may be related to the rather large size of the known button system that is designed to draw attention to it. One specifically suitable known button system is described in WO2012/173475 of the two inventors of the present invention.

Using the known button system allows the shoe system to be personalized by the user to a large extent. Furthermore it allows the design of new and unique footwear as will follow from the description of the preferred embodiments.

According to a first unique and elegant preferred embodiment the upper shoe part comprises a strap for engaging the foot, wherein the button closure further comprises a button hole to receive the button, wherein one or more button holes are situated on one or more outer ends of the strap. Different forms of straps, such as V-shaped straps or T-shaped straps, can be folded over the foot of the user and releasably fastened to the button. The button may either be present on another outer end of the strap or on a thong part intended to be placed between toes of the foot of the user, wherein the thong part is comprised in the sole and wherein the button is attached to the thong part.

According to a different unique preferred embodiment the upper shoe part comprises an ankle strap for engaging the ankle of the foot, wherein the ankle strap is further arranged for engaging the button. The ankle strap may be used alone or in combination with the straps engaging the foot as described above.

In yet another unique preferred embodiment the decorative member is arranged to form the upper shoe part. Such a decorative member may be used alone as well as in combination with the straps and/or ankle straps described above.

When a strap is used for engaging the foot the fastening means need to be supplemented with auxiliary fastening means to releasably fasten the strap to the sole at a second position. In the known shoe system the sole is provided with a slot extending over the width of the shoe forming a passage for the strap. As an alternative according to the invention the sole is provided with one or more bores extending over the width of the shoe and the straps are provided at the outer ends with auxiliary fastening means for releasable attachment to the bores.
