<p>A stiffness mechanism (10;110) for a boot (B) having a shell (S) with a flexibility slot (12;112) and a cuff (C) pivotally secured to the shell includes a buckle assembly (116) selectively engageable with a portion of the shell for selectively securing the cuff to the shell. A blocking assembly (18;120) is selectively disposable within the flexibility slot for selectively increasing the stiffness of the shell. A lever assembly (14;114) is pivotally disposed between the buckle assembly and the blocking assembly. When the lever assembly is moved into a first position, the cuff is secured to the shell and a portion of the blocking assembly is disposed within the flexibility slot to increase the stiffness of the shell. When the lever assembly is moved into a second position, the cuff is pivotal with respect to the shell and the blocking assembly is at least partially disengaged from the flexibility slot to increase the flexibility of the shell.</p> |
