ABSTRACT:
For sport boot systems incorporating a pliable inner liner within a rigid outer shell, such as for ski or snow board type boots, an inner liner of foam material is provided with a single bifurcation at its outer side to provide a tongueless entry access opening. Relief structures are positioned at the front of the liner to provide enhanced forward flexibility and to increase comfort.
