         2 . The flexor unit according to  claim 1 , wherein the front flexor portion is arranged to abut with a front underside portion of a ski boot when the ski boot is attached to the ski binding. 
     
     
         3 . The flexor unit according to  claim 1 , wherein the rear flexor portion is arranged to abut with an underside portion of the ski boot behind the rotation pin when the ski boot is attached to the ski binding. 
     
     
         4 . The flexor unit according to  claim 1 , wherein the base element is provided with part of a snap-fit connector for attaching the flexor unit to the ski binding, which is provided with a mating part of the snap-fit connector. 
     
     
         5 . The flexor unit according to  claim 1 , wherein the base element further comprises a pin receiving portion which is sized and shaped to receive at least a part of a rotation pin of a ski boot;
 wherein the base element further comprises a boot plate which is rotationally attached or attachable, or formed as an integral part of the base element which is rotational with respect to the remaining parts of the base element,   wherein the boot plate is located such that it will make contact with the underside of a ski boot when the ski boot is attached to a ski binding comprising the flexor unit.   
     
     
         6 . The flexor unit according to  claim 4 , wherein the part of the snap-fit connector comprises a flexible strip which can deform upon engagement with the ski binding and snaps back into place when the flexor unit is correctly in place to stop accidental disengagement, such that the flexor unit can be slidably engaged with the ski binding; the base portion comprising one or more wing portions which are located at the other end of the base portion to the snap-fit connector. 
     
     
         7 . The flexor unit according to  claim 1 , wherein the base portion further comprises an under-clip located at the underside of the base portion for providing a further attachment point between the flexor unit and the ski binding. 
     
     
         8 . The flexor unit according to  claim 1 , wherein the base portion is made from a material which is cold tolerant and which is still readily flexible at temperatures as low as −20° C. 
     
     
         9 . The flexor unit according to  claim 1 , wherein the front flexor portion is provided with a boot contact surface which is located such that the front underside portion of a ski boot will be in contact with the boot contact surface when the ski boot is attached to the ski binding. 
     
     
         10 . The flexor unit according to  claim 9 , wherein the boot contact surface comprises first and second pre-tensioning surfaces which are structured to match the contour of the lower surface of the ski boot when attached to the ski binding such that the lower surface of the ski boot is in contact with each of the first and second pre-tensioning surfaces. 
     
     
         11 . The flexor unit according to  claim 9 , wherein the plane of the first pre-tensioning surface extends generally upward and forward from the joining point of the first and second pre-tensioning surfaces, and the second pre-tensioning surface extends generally downward and backward from this joining point so as to create a boot surface which has an open L-shape. 
     
     
         12 . The flexor unit according to  claim 11 , wherein the position of the boot contact surface, and the first and second pre-tensioning surfaces, with respect to the pin receiving slot, can be chosen to increase or decrease the amount of deformation of the entire front flexor portion which is required to allow a ski boot to be attached to a ski binding containing the flexor unit. 
     
     
         13 . The flexor unit according  claim 9 , wherein the flexor element comprises a hole through the flexor element to allow the boot plate to pass through when the flexor element is integrated with the base element. 
     
     
         14 . The flexor unit according to  claim 13 , wherein a recess is provided in the boot contact surface to receive the boot plate such that the boot plate and the boot contact surface provide a uniform combination surface. 
     
     
         15 . The flexor unit according to  claim 1 , wherein the flexor element and base element are one of:
 a) independently fabricated and stuck together to form the flexor unit;   b) double moulded to form the flexor unit.   
     
     
         16 . A ski binding which is structured to accommodate the flexor unit of  claim 1 , wherein the ski binding comprises a first slot which is sized to allow the flexor unit to slide therein, and a bridge piece in the region of the first slot, wherein the bridge piece is located so as to interact with and hold the flexor unit in the ski binding. 
     
     
         17 . The ski binding according to  claim 16 , further comprising one or more second slots which are sized and shaped to receive wing portions of the base element, if provided; and an under lock which is sized and shaped to receive the under clip of the base element, if provided. 
     
     
         18 . The ski binding according to  claim 16 , wherein the first slot is positioned such that the flexor unit, when attached to the ski binding, will be located such that the pin receiving slot and the pin receiving portion will be aligned with a pin fastener on the ski binding, the pin fastener being designed to attach the rotation pin of the ski boot to the ski binding.
