Ski binding units for fasting a ski boat at the toe and heel of the boat. The toe binding unit applies cantilever loading to the toe of the boot through an abutment which overlaps the toe of the boot. The abutment is hinged to the base which is secured on the ski. A shear wire temporarily prevents the abutment from swinging vertically relative to the base. The heel binding unit supports the heel on roller bearings and yieldably clamps the heel against the bearings by means of a snap action spring blade. The heel unit releases the heel of the boot laterally while the toe pivots about the toe unit, when a predetermined lateral force is applied. Both the toe unit and heel unit are capable of releasing vertically when predetermined forces are applied to the respective units.
