Testers were surprised by the contrast between this boot’s looks and initial fit and how it performed on snow. The unusual Apex looks like a snowboard boot fitted into an open-throated alpine-shell-like exoskeleton. Twin Boa systems customize lace-fit tension between the upper and lower portions of the soft boot. Because the fit tension is largely controlled by the soft boot’s lacing system, it can work for a variety of foot and leg shapes. The skiing performance was surprisingly good, testers said, especially for relaxed cruising.
