Sole device

Abstract

The invention relates to a sole device (10) for shoes, in particular for ballet shoes, comprising: a backbone sole (12) having a plurality of vertebral bodies (14), which are connected to one another by joint portions (16); and intermediate spaces (18) between the vertebral bodies (14), which intermediate spaces are associated with the joint portions (16), the sole device also comprising a plurality of sticks (20) for inserting into the intermediate spaces (18). According to the invention, at least two of the plurality of sticks (20) have different thicknesses and/or cross-sections and at least one of the intermediate spaces (18) is designed to alternatively receive sticks (20) having different thickness and/or cross-sections.

1 . A sole device for shoes, in particular for ballet shoes, comprising:
 a backbone sole with a plurality of vertebral bodies, which are connected to one another by joint portions, and intermediate spaces, associated with the joint portions, between the vertebral bodies, wherein the sole device further comprises a plurality of sticks for inserting into the intermediate spaces,   
       and wherein at least two of the plurality of sticks exhibit different thicknesses and/or cross-sections, and that at least one of the intermediate spaces is configured such as to receive alternatively sticks with different thicknesses and/or cross-sections. 
     
     
         2 . The sole device according to  claim 1 , wherein a plurality, and preferably all, of the intermediate spaces are configured such as to receive alternatively sticks with different thicknesses and/or cross-sections. 
     
     
         3 . The sole device according to  claim 1 , wherein at least one of the sticks exhibits such a thickness and/or such a cross-section that, in a state in which it is inserted into an intermediate space, it provides a straight course run for the associated joint portion. 
     
     
         4 . The sole device according to  claim 1 , wherein at least one of the sticks exhibits such a thickness and/or such a cross-section that, in the state in which it is inserted into an intermediate space, it presses the vertebral bodies adjacent to the intermediate space apart from one another. 
     
     
         5 . The sole device according to  claim 1 , wherein at least one of the sticks exhibits such a thickness and/or such a cross-section that, in the state when inserted into an intermediate space, it allows for the vertebral bodies adjacent to the intermediate space to come closer to one another. 
     
     
         6 . The sole device according to  claim 1 , wherein at least one of the intermediate spaces exhibits a rectangular or trapezoidal cross-section. 
     
     
         7 . The sole device according to  claim 1 , wherein at least one of the sticks exhibits a non-rotationally symmetric cross-section, and is configured such as to be rotatably inserted into at least one of the intermediate spaces. 
     
     
         8 . The sole device according to  claim 7 , wherein the at least one rotatable stick exhibits an oval cross-section. 
     
     
         9 . The sole device according to  claim 8 , wherein the at least one rotatable stick exhibits an elliptical cross-section. 
     
     
         10 . The sole device according to  claim 1 , wherein the sticks are configured for detachable insertion into the intermediate spaces. 
     
     
         11 . A shoe, comprising a sole device according to  claim 1 . 
     
     
         12 . The shoe according to  claim 11 , in which the shoe is selected from the group consisting of a ballet shoe, an orthopedic shoe, a sports shoe, and a running shoe.
