Take your sport ice and mixed climbing to a whole new level with the premier MEGA ICE boot! Boots are the connection to the medium - where closeness and sensitivity are of primary importance and none are better for radical new school ice and rock dancing. This sleek boot sports a low profile, Vibram XSV rubber rand, stretchable Schoeller Dynamic gaiter with elastic cuff and insulating pile and waterproof zipper. The absolute minimum bulk for threading figure 4's and climbing with your heels above your waist. Weighing just over 1 1/2 lbs each the MEGA ICE's inner is crafted from low stretch, supple and highly breathable synthetic microfiber with 3 mm of insulating felt and a heat reflective Alumina layer (the same material used on the OLY MONS EVO expedition boot). Supportive carbon reinforced 7mm Nylon insole provides a stable yet sensitive platform for input from each of your crampon points whether hanging upside down from a pocket or stemming across space to a distant ice pillar. Included are the modular Grivel Racing bolt on crampon which can be configured to your preferences (spurs/no spurs, offset/centered front points). Climb with greater sensitivity and precision - get your MEGA ICEs early and start practicing your dry toolin' and footwork! Delivered anywhere in North America.
