<p>The object of this invention is a shoe with an incorporated system intended to transform the shoe into a roller skate, the shoe (1) itself having a sole (2) of a thickness which is sufficient to receive internally two or more fixed or mobile axes (3) which are arranged transversally and introduced into holes (4) in the sole (2); the shape of the axes matches the hole (4) so as to obtain a perfect coupling between both parts; a wheel (5) can be coupled at each external extremity of the axes (3) by threading, pressure or any other fixing means.</p> |
