  • metatarsal cushion enhances the positive effects of using the claimed insole, but its use is not advisable in all cases. So, it can be used in everyday shoes. However, it is not recommended to use the declared insole with a metatarsal roller in sports shoes that involve active movement, jumping, running, etc., since this can lead to increased stress on the foot, pain and other undesirable effects during prolonged physical and cyclic loads (for example, running more than 3000 meters).

  • Pronation zone 3 allows you to soften the load on the foot while walking, and its shape (cross-sectional profile) is selected taking into account the individual characteristics of the patient's foot.
  • This zone of 3 pronation is the most important part of the declared insole, and it is thanks to it that, in the first place, it provides increased comfort during prolonged use of the insole, improves the dynamics of foot adjustment, reduces or even completely eliminates the pain effect on the foot and the musculoskeletal system as a whole.

  • the metatarsal roller 5 is placed at the highest point of the transverse part of the foot, it can reach a height of 3 to 20 millimeters.

  • the metatarsal roller 5 has an elongated shape or an elongated-curved shape of the "comma" type. The exact shape and exact location of the metatarsal ridge 5 can be determined after examining the patient's foot.

Abstract

L'invention se rapporte au domaine de la médecine, notamment de l'orthopédie, et peut être utilisée pour la prévention et le traitement de l'appareil locomoteur, ainsi que pour le traitement du pied et de ses affections comme le pied plat et une déformation de pied plat valgus des pieds. Cette semelle comprend un renfoncement de forme allongée définissant une zone de pronation (3) et s'étendant le long du côté externe de la semelle depuis l'endroit (1) où se situe l'apophyse latérale du talus jusqu'à l'endroit où se situe l'extrémité distale de la troisième phalange du cinquième orteil; dans la section transversale dudit renfoncement, le point le plus élevé de la zone de pronation (3) se situe essentiellement à proximité du côté externe de la semelle. La semelle peut en outre comprendre une tige métatarsienne (5) disposée à proximité de l'endroit où se situe la seconde articulation métatarso-phalangienne. Ce procédé de production de semelle consiste à obtenir une image du pied, à déterminer sur celle-ci la position du renfoncement de forme allongée définissant une zone de pronation (3) et s'étendant le long du côté externe de la semelle depuis l'endroit (1) où se situe l'apophyse latérale du talus jusqu'à l'endroit où se situe l'extrémité distale de la troisième phalange du cinquième orteil, et former une semelle avec ladite zone de pronation (3). La semelle est formée de sorte que, dans la section transversale du renfoncement, le point le plus élevé de la zone de pronation se situe essentiellement à proximité du côté externe de la semelle. Le résultat technique consiste en l'obtention d'une dynamique voulue de changement de la voûte plantaire, en une accélération du processus de correction de la forme du pied, en une élimination partielle ou complète des sensations douloureuses dans le pied et l'appareil locomoteur.
