The ST Rotation 7 Binding is the previous season's radical Dynafit alpine touring binding with a pivoting toe and DIN-rated release values. The lower DIN makes it ideal for aggressive backcountry skiing. A little over a pound per piece, the ST Rotation's lightness complements skiers who want a light skin up as well as an aggressive ride down. Its pivot toe not only combats pre-releasing after sudden impacts, it also assists stepping in on steep terrain. The ST Rotation is compatible with Dynafit's TLT or any other tech alpine touring boot. The spring-tensioned toe piece has a front lever for a secure lock-in, and heel rotates out of the way for quick-and-easy transitions. Dynafit integrated the heel into the baseplate for added stiffness that retains 10mm forward pressure to retain a constant release value from the binding's first skin to its last.
