Abstract
A ski binding for cross-country ski fixes the front section of a boot such that the heel of the boot can be freely lifted off. The boot is fixed to the binding by an interlocking engagement of its sole, and by holding down the front end of the sole. Elements are also provided that laterally guide and stabilize the sole and, hence, the boot.
