Walking device

Abstract

The walking device has a shoe bottom with a midsole. A soft heel part is arranged in a recess of the midsole and the outsole has a form that is rounded convexly in the walking direction. The reinforcing element, forming an insole, is arranged on the upper surface of the midsole and fastened to it. In the production of the walking device, the upper is joined to the reinforcing element to form a structural unit, which is then mounted on the midsole, for example by adhesive bonding.

1 . A walking device with a shoe bottom, which has a midsole, extending over a heel region, a midfoot region and a ball and toe region, a soft heel part, arranged in a recess of the midsole, and an outsole, which is kept—in the unloaded state—in a form that is rounded convexly in the walking direction by the midsole and the soft heel part, an upper, arranged on the shoe bottom, and a reinforcing element, which has such stability that the midsole is at least almost free from bending—with respect to loads during standing and walking—in its portion located above the soft heel part, wherein the reinforcing element, forming an insole, is arranged on an upper surface of the midsole, facing away from the outsole, and is fastened to said surface. 
     
     
         2 . The walking device as claimed in  claim 1 , wherein the upper is fastened to the reinforcing element. 
     
     
         3 . The walking device as claimed in  claim 1 , wherein the upper is fastened directly to the reinforcing element and to the midsole. 
     
     
         4 . The walking device as claimed in  claim 1 , wherein the reinforcing element covers the upper surface of the midsole at least almost completely. 
     
     
         5 . The walking device as claimed in  claim 1 , wherein the reinforcing element has at least one reinforcing rib in the midfoot region. 
     
     
         6 . The walking device as claimed in  claim 5 , wherein the reinforcing rib protrudes into the heel region. 
     
     
         7 . The walking device as claimed in  claim 1 , wherein the reinforcing element is at least almost rigid—with respect to the loads during standing and walking—in the heel region and midfoot region. 
     
     
         8 . The walking device as claimed in  claim 1 , wherein the reinforcing element is flexibly formed, at least in a portion of the ball and toe region. 
     
     
         9 . The walking device as claimed in  claim 1 , wherein the reinforcing element is produced from at least one hard and one soft plastic component. 
     
     
         10 . The walking device as claimed in  claim 1 , wherein the curvature of the outsole has in the heel region a radius of approximately 150 mm to 200 mm, in the midfoot region a radius of approximately 250 nm to 350 nm and in the ball and toe region a radius of approximately 350 nm to 480 nm. 
     
     
         11 . The walking device as claimed in  claim 1 , wherein the soft heel part—in a rear portion—is made wider on its underside, facing the outsole, than on its upper side, facing the midsole. 
     
     
         12 . The walking device as claimed in  claim 1 , wherein the soft heel part has a greater thickness on the inner side of the walking device than on the outer side. 
     
     
         13 . The walking device as claimed in  claim 1 , wherein the reinforcing element, and consequently the insole, has in the heel region a bending moment of approximately 4500 to 6000 Nmm. 
     
     
         14 . The walking device as claimed in  claim 1 , wherein the recess is formed continuously, in a direction transverse to the walking direction.
