         4 . The front binding device for securing a boot to a gliding board as claimed in  claim 3 , wherein the jaw ( 11 ) comprises a partially cylindrical front surface ( 26 ) which comes to bear against a cylindrical surface ( 27 ) of the front end stop ( 25 ).  
     
     
         5 . The front binding device for securing a boot to a gliding board as claimed in  claim 3 , wherein the device comprises several pistons ( 29 ,  29 ′) operated by respective springs ( 18 ,  18 ′) mounted in parallel.  
     
     
         6 . The front binding device for securing a boot to a gliding board as claimed in  claim 1 , wherein the jaw ( 11 ) exhibits a shoulder ( 13 ) for bearing against a binding element ( 2 ) belonging to a boot.  
     
     
         7 . The front binding device for securing a boot to a gliding board as claimed in  claim 1 , wherein the jaw is able to move about an axis ( 30 ), remains bearing against the upper surface ( 33 ) of the device, this surface having a downward slope in the form of an arc of a circle, followed by the jaw ( 11 ), in the event of a fall with twisting so as to retract the jaw in such a fall.  
     
     
         8 . A sports boot able to be fixed to a gliding board comprising a sole ( 1 ), comprising a rear kerb to be fixed by the jaw of a heel piece, wherein the sole ( 1 ) comprises a hollowed-out region ( 6 ), a binding element ( 2 ) having the shape of a V ( 3 ) pointing toward the front of the boot, the hollow of the V-shape ( 3 ) being approximately centered on the width of the boot, positioned toward the front of the boot and placed above the hollowed-out region ( 6 ).  
     
     
         9 . The sports boot as claimed in  claim 8 , wherein the binding element ( 2 ) has a V-shape the opening of which ranges between 15 and 35 millimeters and the depth of which ranges between 5 and 10 millimeters.  
     
     
         10 . The sports boot as claimed in  claim 8 , wherein the distance between the end of the rear kerb and the point of the V ( 3 ) of the binding element ( 2 ) of the sole ( 1 ) of the boot ranges between 19 and 24 centimeters.  
     
     
         11 . The sports boot as claimed in  claim 8 , wherein the distance between the end of the rear kerb and the point of the V ( 3 ) of the binding element ( 2 ) of the sole ( 1 ) of the boot ranges between 19 and 22 centimeters for a shoe size of between 23.5 and 27.5 and ranges between 22 and 24 centimeters for a shoe size of 27.5 or higher.  
     
     
         12 . The sports boot as claimed in  claim 8 , wherein the sole additionally comprises two stiff bearing regions ( 5 ) arranged longitudinally on each side of the hollowed-out region ( 6 ) to bear against a corresponding surface on the gliding board.  
     
     
         13 . The sports boot as claimed in  claim 8 , wherein the sole ( 1 ) comprises a front region ( 7 ) that is curved to make walking easier.  
     
     
         14 . The sports boot as claimed in  claim 8 , wherein the sole ( 1 ) is made of rubber and the binding element ( 2 ) and/or the stiff regions ( 5 ) are made of metal.  
     
     
         15 . A binding/sports boot system for securing the boot to a gliding board comprising a heel piece and which comprises a front binding device comprising a jaw connected to a device comprising a release mechanism, wherein the jaw comprises a securing bar having a bearing surface sloping upward and a base kept in contact with the device by a connection allowing the jaw to rotate laterally and vertically with respect to the device and comprises a boot as claimed in  claim 8 .  
     
     
         16 . A set of boot/binding systems as claimed in  claim 15 , comprising a set of boots of different shoe sizes, able to be fixed to a gliding board comprising a sole, comprising a rear kerb to be fixed by the jaw of a heel piece, wherein the sole comprises a hollowed-out region, a binding element having the shape of a V pointing toward the front of the boot, the hollow of the V-shape being approximately centered on the width of the boot, positioned toward the front of the boot and placed above the hollowed-out region; 
 wherein the separation between the heel piece and the front binding devices, comprising a jaw connected to a device comprising a release mechanism, wherein the jaw comprises a securing bar having a bearing surface sloping upward and a base kept in contact with the device by a connection allowing the jaw to rotate laterally and vertically with respect to the device, in the set of binding devices corresponding to the set of boots of different shoe sizes is constant and non-adjustable.
