ABSTRACT:
Apparatus for connection to a cross-country ski for laterally guiding a ski shoe having a front end atached to the ski at a position forwardly of the rear of the shoe whose heel is vertically movable on the ski in the longitudinal median plane thereof includes a longitudinally extending guide rib adapted to cooperate with a longitudinal groove of complementary shape in the sole of the ski shoe. The groove successively includes, from front to rear, a first region beneath the toes of the foot of the wearer of the shoe, a second region beneath the ball of the foot of the wearer, a third region beneath the arch of the foot of the wearer, and a fourth region beneath the heel of the foot of the wearer. The rib has opposite lateral sides defining the width of the guide, and a top surface defining the height of the guide. Both the slope of the sides relative to the longitudinal median plane of the ski, and the height of the guide, are nonconstant functions of the length of the guide.
