A ski binding comprising:

• base plate means having upper and lower surfaces for supporting a ski boot, said base plate means having a recess means formed therein;
• sole holder means mounted to said base plate means for receiving the sole of a ski boot;
• and
• an anti-friction means for controlling the friction between the ski boot sole and the sole holder means during a lateral release of the ski boot from the sole holder, said anti-friction means comprising:
• a rocking member pivotally supported in the base plate for rocking movement about a fixed longitudinal axis of the ski binding relative to said base plate and cooperating with said recess means, said rocking member having at least one transversely disposed end portion along each side of said longitudinal axis, said end portions having at least one upwardly extending protrusion depressingly engageable with said ski boot sole to rock said rocking member to reduce friction between the ski boot sole and the sole holder.
