Definitions

  • the present invention relates to a lower sole climbing shoe.
  • Climbing is practiced either on natural rocks, for example cliffs, or on sites equipped with artificial catches, such as gyms equipped with climbing walls.
  • a climbing boot must have dimensions perfectly adapted to the user's foot.
  • a climbing shoe includes a sole made of a material consisting of a natural or synthetic rubber gum, having great flexibility, good deformability, and significant adhesion capabilities on any type of surface and particularly on rough surfaces that are those corresponding to the nature of the rock.
  • On this sole is mounted a rod generally made of a very flexible textile material, reinforced locally on the kick and on the back of the heel by straps.
  • This outfit is the result of the quality of adhesion of the rubber, also related to the muscular pressure exerted by the climber, and the quality of grip of the rubber constitutive of the sole.
  • the object of the invention is to improve the qualities of adhesion and grip of the sole on the catches.
  • the bottom sole of the climbing shoe which it concerns, made of a flexible material of gum type, natural or synthetic, having a general appearance of smooth surface, is characterized in that it comprises, at least in the zone located in its front part, grooves obtained by etching.
  • the depth and the width of the grooves are between 1 and 2 mm and preferably of the order of 1.5 mm.
  • the etching of the grooves is performed by laser radiation.
  • the micro-grooves in the sole facilitate the mechanical deformation of the rubber plate by softening it.
  • the contact surface of the sole with the catches made on the rock or with the artificial catches increases, which increases the adhesion.
  • micro grooves facilitate the deformation of the sole, so facilitate the adaptation of the boot and in particular the sole to different morphologies of the foot.
  • this sole comprises a first series of grooves substantially parallel to the inner edge of the sole and extending substantially from the metatarsal support zone located at the base of the big toe to the base of the sole. internal plantar arch.
  • This first series of grooves makes it possible to improve the mechanical deformation of the soleplate, and thus to soften the latter, which allows an increase in the contact surface between the soleplate and a grip, reinforcing the grip of the soleplate on the soleplate. outlet.
  • most of the grooves of the first series are continuous.
  • this sole comprises at least two second series of grooves, and preferably three series of grooves, extending from the first series of grooves and each having a general transverse orientation to the outer edge of the groove. the sole, that is to say substantially perpendicular to the tangent to the outer edge of the sole at the theoretical meeting point between the series of grooves considered and the outer edge of the sole.
  • the grooves of the second sets of grooves promote surface deformation of the sole in its central area which is important for improving progression on plates and rounded outlets.
  • the grooves of the second series are continuous.
  • the grooves of the first and second series of grooves are located at a distance from the peripheral edge of the soleplate, delimiting with this edge a non-grooved area.
  • This smooth zone located between the peripheral edge of the sole and the grooved areas, of a width of the order of 10 to 15 mm, ensures a precision support and good adhesion of the structure under load.
  • the sole comprises short grooves, of a length of between 3 and 10 mm, arranged between the grooves of the second series and extending into the area of the plantar arch.
  • Figure 1 is a side view of the inner face of this slipper.
  • Figure 2 is a view of the outer face of the sole.
  • the figure 1 represents a climbing shoe.
  • This climbing shoe has an outer sole 2 made of a rubber or synthetic rubber, going up along the heel.
  • On this sole 2 is fixed a rod 3 made of a light textile material, reinforced by straps 4, 5 passing respectively behind the heel and on the upper face of the foot.
  • the closure of the liner is performed using straps 6 self gripping.
  • the sole 2 is shown in more detail at figure 2 .
  • This sole has three main parts, namely a front portion A, a central portion B corresponding to the plantar arch, and a rear portion C corresponding to the heel.
  • the sole has a first series of grooves 7 substantially parallel to the inner edge of the sole, extending substantially from the metatarsal support zone 8 located at the base of the big toe up to the base 9 of the plantar arch.
  • the depth and width of the grooves 7 are between 1 and 2 mm and preferably of the order of 1.5 mm.
  • These grooves 7 are continuous, and connected to each other at their ends by transverse grooves.
  • the sole 2 comprises three second series of grooves 10, extending from the first series of grooves 7, the grooves being of generally transverse orientation to the outer edge of the sole. These grooves are continuous.
  • the grooves belonging to the first series 7 and the grooves belonging to the second series 10 are set back from the peripheral edge of the sole, forming with this edge a smooth zone 12. Between the zones of the grooves 7 and 10 are formed short grooves 13 of a length of between 3 and 10 mm. Between the series of grooves 10, these short grooves 13 are substantially parallel to the long grooves of the series of grooves 10, while in the central portion B of the sole, they occupy an orientation more and more longitudinal.
  • micro grooves promote the mechanical deformation of the sole, improves its adaptation to the field, and also facilitates its adaptation to the morphology of the foot of the user.
  • grooves may also be provided in the heel area C, or grooves may be provided in the lateral edge of the sole, or in a zone made of rubber covering the user's toe area.
  • the term climbing shoe must be taken in the broad sense, this sole can also equip other types of footwear for climbing, such as ballerinas.
