"mass production of available shoe models", sending the users to the so-called "common place"

This collateral effect of a mode! of capitalist commerce also reaches the flip-flops and sanda! type shoes which are characterized by basically presenting a component strap(s) to a sole

One evaiuation in the form of production of this type of shoe shows that the straps normally have their ends glued between the sole and the upper sole, sn the specific case of sandals produced with a leather base

For sandals and flip-flops manufactured with polyester material, the aforementioned straps are designed in such a way so as to have terminals on their ends shaped as balloons, cylinders and oblong, among other shapes, where these are mounted by compression close to the holes previously defined on the sole, thus enabling as adequate fit

Taking the sandals manufactured with elastomeπc materials, normally the fastened strap(s) no longer permrt(s) their disassembly, and if it is tried, the terminal are usually ruptured, destroying the sandal, and therefore causing damages to the final user Thus, this existing constructive condrtson forces the final consumer, chiefly women, to acquire several sandal models, if they intend to have a large portfolio of this type of footwear, which fact implies a high acquisition cost

Due to this realistic scenario, it is always necessary to develop new models, with use flexibility, practical alteration of their esthetic or ornament, chiefly for the feminine market, always bearing in mind the differentiation m relation to al! existing options in the footwear market

OBJECTIVE OF INVENTION.

Due that contained in the principles of the technique, the applicant conceived, in an unprecedented manner, the method to fasten the straps on the sole of sandals or fitp-fiops, whose differentiating detail is to permit such footwear to present the flexibility to change the decorative image, leading the final consumer to feel more attractive and satisfied, at a reduced cost

For such differentiation condition to be obtained, the new flip-flops and sandal type shoes present constructiveness as the component strap(s) present on their end threaded places, whose function lies sπ receiving, once positioned over the sole, the assembly of terminal elements by the inner part of the same sole, being that such assembly if characterized by the great practicality and ease of execution where its disassembly is equipped with this same facility, being a motivational factor for the end consumer, especially the female public, to execute and exchange straps with different aesthetic and decorative effects
