En las figuras reseñadas, especialmente en la figura 2, se ha representado un determinado ejemplo de realización práctica para un calzado al que se ha aplicado la invención, siendo de señalar que la configuración de dicho calzado obedece a un mero ejemplo de realización práctica, que puede variar sin prácticamente limitación alguna al respecto, y sin que ello afecte a la esencia de la invención.In the figures outlined, especially in the Figure 2, a certain embodiment example has been represented practice for footwear to which the invention has been applied, being to point out that the configuration of said footwear is due to a mere practical embodiment example, which can vary without practically any limitation in this regard, and without affecting the essence of the invention.

Sea cual fuere la configuración del corte (1) del calzado, así como la configuración de su suela (2), el diseño de la cara inferior de esta última, etc, el sistema de la invención se centra en el hecho de que dicha suela (2) a nivel del tacón (3), genera una amplia cámara (4), preferentemente abierta hacia las zonas laterales de la suela, tal como muestra la figura 1, aunque también podría estar cerrada, cámara (4) en la que, de acuerdo con la esencialidad de la invención, se establecen una pareja de imanes permanentes (5-5'), coaxiales, enfrentados a través de polos coincidentes, de manera que entre ellos se genera un considerable esfuerzo repulsivo, situándose obviamente uno de dichos imanes (5) sobre la base superior de la cámara (4), y el otro (5') sobre la base inferior, y tendiendo en todo momento a mantener al tacón (3) en su conjunto en condiciones de máxima altura para la cámara (4).Whatever the configuration of the cut (1) of footwear, as well as the configuration of its sole (2), the design of the underside of the latter, etc., the system of the invention it focuses on the fact that said sole (2) at the heel level (3), generates a wide chamber (4), preferably open towards lateral areas of the sole, as shown in figure 1, although it could also be closed, camera (4) in which, according to the essentiality of the invention, a pair of magnets are established permanent (5-5 '), coaxial, faced through of matching poles, so that between them a considerable repulsive effort, obviously placing one of these  magnets (5) on the upper base of the chamber (4), and the other (5 ') on the lower base, and tending at all times to keep the heel (3) as a whole in conditions of maximum height for the camera (4).

En el sistema participa además un resorte de ballesta (6), destinado a encajar ajustadamente en la cámara (4) y con una triple finalidad, por un lado fijar y posicionar convenientemente los imanes permanentes (5-5'), en todo momento, por otro lado complementar el efecto de dichos imanes por su propia naturaleza elástica y como un complemento amortiguador, y finalmente permitir una regulación en la amortiguación del sistema, para adecuarla a las necesidades de preferencias del usuario, merced a que los dos brazos del resorte de ballesta (6) están relacionados mediante un tornillo (7) y su complementaria tuerca (8), accesibles a través de un pequeño orificio (9) de la base del tacón (3).The system also includes a spring of leaf spring (6), designed to fit tightly into the chamber (4) and with a triple purpose, on the one hand fix and position conveniently permanent magnets (5-5 '), in at all times, on the other hand complement the effect of these magnets by its own elastic nature and as a complement shock absorber, and finally allow regulation on the damping of the system, to adapt it to the needs of user preferences, thanks to the two spring arms of crossbow (6) are related by means of a screw (7) and its complementary nut (8), accessible through a small hole (9) of the heel base (3).

En la práctica y de acuerdo con el ejemplo mostrado en la figura 1, en el sistema pueden participar dos flejes (6-6'), destinados a adaptarse entre sí con interposición de los imanes permanentes (5-5') duplicando el efecto ballesta y facilitando la fijación de dichos imanes permanentes, disponiendo uno de estos resortes de ballesta (6') de cuellos interiores (10), de embocadura estrangulada, para el paso del tornillo (7) y asentamiento de la tuera (8) y de la cabeza (11) de dicho tornillo (7), a la vez que incorpora también en la zona extrema de sus ramas laterales patillas troqueladas (12) para acoplamiento a presión de los imanes permanentes (5-5').In practice and according to the example shown in figure 1, two strips can participate in the system (6-6 '), intended to adapt to each other with interposition of permanent magnets (5-5 ') doubling the crossbow effect and facilitating the fixation of said permanent magnets, having one of these springs springs (6 ') of inner necks (10), of strangulated mouth, for the passage of the screw (7) and settlement of the tuera (8) and of the head (11) of said screw (7), while also incorporating the extreme area of its side branches sideburned pins (12) for pressure coupling of permanent magnets (5-5 ').

Esta estructuración conlleva que el calzado, en la zona del antepié, ha de ser una material de alta elasticidad y elevada fuerza de recuperación, siendo además resistente al desgaste, para recoger el rebote del tacón e imprimir fácil y cómodamente un gran impulso al antepié.This structuring implies that footwear, in the forefoot area must be a high elastic material and high recovery force, being also resistant to wear, to pick up the heel bounce and print easy and comfortably a great boost to the forefoot.

De acuerdo con esta estructuración, cuando el usuario desarrolla las operaciones de andar o correr, se producen los siguientes efectos:According to this structuring, when the user develops walking or running operations, occur The following effects:

En primer lugar el impacto del talón con el suelo queda amortiguado, absorbiendo la mayor parte de la energía por efecto de la aproximación de los imanes y de la flexión de la ballesta, produciéndose una deformación suave y acumulando energía el sistema.First the impact of the heel with the soil is cushioned, absorbing most of the energy due to the approach of the magnets and the flexion of the crossbow, producing a gentle deformation and accumulating energy the system.

En el paso del talón al medio pie y antepié, continuando con el movimiento, se reduce sensiblemente el tiempo dado que mientras se está produciendo la amortiguación (alargada), el pie va avanzando, por lo que se reduce el tiempo del impás entre el talón y el antepié.In the heel step to the middle foot and forefoot, continuing with the movement, time is significantly reduced since while damping (elongated) is occurring, the foot is advancing, so the time of the moment between Heel and forefoot.

Finalmente, cuando el sistema tiende a volver a su posición original, devuelve la energía acumulada, el antepié se encuentra en disposición de impulso del suelo, por lo que es catapultado con esta energía complementaria acumulada, que es aplicada al pie en la zona del talón, como si de un rebote se tratara.Finally, when the system tends to return to its original position, returns the accumulated energy, the forefoot is found in ground impulse arrangement, so it is catapulted with this accumulated complementary energy, which is applied to the foot in the heel area, as if from a bounce will try.

Se facilita de esta manera la acción de andar de forma muy considerable, obteniéndose como resultado no sólo un calzado estéticamente atractivo y novedoso, sino además confortable, sin el menor riesgo de lesiones para los pies del usuario y con un acusado incremento de rendimiento.This facilitates the walking action of very considerable form, resulting in not only a aesthetically attractive and novel footwear, but also comfortable, without the slightest risk of injury to the feet of the user and with a marked increase in performance.
