Sport shoe

Abstract

This sport shoe includes an outer sole suitable for ground contact, an inner sole situated under a foot of an athlete, and an intermediate sole between the outer and inner soles. The outer sole is divided, along a longitudinal axis of the shoe, into at least three transverse zones including a front zone located at least partially below the toes of the foot, a median transverse zone provided to be at least partially located below a region of the foot extending between the base of the toes and a front end of the arch of the foot, and a rear zone provided to be located at least partially below a region of the foot extending backward from the front end of the arch of the foot. The three transverse zones are separated by transverse flexion lines whose flexibility is greater than the flexibility of the three transverse zones.

         12 . A sport shoe, in particular for tennis, comprising, inter alia:
 an outer sole adapted to be in contact with the ground,   an inner sole provided to be situated below an athlete's foot,   an intermediate sole inserted between the outer sole and the inner sole,   
       the outer sole being divided, along a longitudinal axis of the shoe, into at least three transverse zones comprising:
 a front zone provided to be located at least partially under the toes of the foot, 
 a median transverse zone provided to be at least partially located below a region of the foot extending between the base of the toes and a front end of the arch of the foot, 
 a rear zone provided to be located at least partially below a region of the foot extending backward from the front end of the arch of the foot, 
 
       the three transverse zones being separated by transverse flexion lines whose flexibility is greater than the flexibility of the three transverse zones,
 the outer sole being divided, along a transverse axis of the shoe, into three longitudinal zones comprising: 
 an inner zone provided to be at least partially under the big toe, 
 a central longitudinal zone provided to be at least partially below the second and third toes, 
 an outer zone provided to be at least partially below the fourth and fifth toes, 
 
       the three longitudinal zones being separated by longitudinal flexion lines whose flexibility is greater than the flexibility of the three longitudinal zones,
 wherein the intermediate sole comprises, superimposed on the front zone and the median transverse zone, three cushions comprising: 
 an inner cushion at least partially superimposed on the inner zone, 
 a central cushion at least partially superimposed on the central longitudinal zone, 
 an outer cushion at least partially superimposed on the outer zone, 
 
       and wherein the inner and outer cushions are made from materials with an energy return capacity greater than the material from which the central cushion is made. 
     
     
         13 . The sport shoe according to  claim 12 , wherein the transverse flexion lines and/or the longitudinal flexion lines are at least partially curved. 
     
     
         14 . The sport shoe according to  claim 12 , wherein the transverse flexion lines and/or the longitudinal flexion lines at least partially have a broken rectilinear shape. 
     
     
         15 . The sport shoe according to  claim 12 , wherein the flexion lines are formed by at least one groove running along an outer surface of the outer sole. 
     
     
         16 . The sport shoe according to  claim 15 , wherein the flexion lines are formed by two grooves running side by side over the outer surface of the outer sole and separated by a rib. 
     
     
         17 . The sport shoe according to  claim 15 , wherein the grooves have a depth comprised between 0.5 and 5 millimeters. 
     
     
         18 . The sport shoe according to  claim 12 , wherein the longitudinal flexion lines have a concave shape whereof the concave side is oriented toward the inside of the shoe. 
     
     
         19 . The sport shoe according to  claim 12 , wherein the transverse flexion lines have a concave shape whereof the concave side is oriented toward the back of the shoe. 
     
     
         20 . The sport shoe according to  claim 12 , wherein the outer sole includes a fourth zone extending behind the rear zone and provided to be located under the heel of the foot. 
     
     
         21 . The sport shoe according to  claim 12 , wherein the inner sole has a lower face divided into three transverse zones and three longitudinal zones superimposed with the transverse zones and the longitudinal zones of the outer sole, these transverse and longitudinal zones of the inner sole being defined by transverse flexion lines and longitudinal flexion lines superimposed on the transverse flexion lines and longitudinal flexion lines of the outer sole, the flexibility of the flexion lines of the inner sole being greater than that of the zones of the inner sole.
