Show Description

Dig deep, get it done and consider this breakthrough boot for alpine, ice and mixed routes. Built as a double boot, but not like a plastic box of yore, it uses an integrated GORE-TEX® gaiter, and removable GORE-TEX inner that functions as basecamp bootie. The design is super-slim, versatile and crafted for warmth on routes that top out around 5000m. Get the warmth of a double boot, the protection of a super-gaiter boot, and all the advantages of a lightweight, low volume single boot that offers precision and speed on technical terrain.

  • Outer gaiter is 3-layer GORE-TEX with a 0.6mm TPU protection film to make it resistant to abrasion and punctures.
  • Removable, stretch GORE-TEX liner bootie is washable, has minimal seams and a rubberized sole.
  • Insulated with 4mm 3D formed perforated PE foam.
  • Adaptive and efficient lacing system with independent Velcro® adjustment, conforms to your foot with no pressure points.
  • T-ZIP watertight front zipper.
  • Carbon fiber insole with an expanded PU foam core to absorb shock.
  • 3D moulded Ortholite™ footbed delivers maximum comfort, breathability and arch support.
  • Injected TPU forms durable heel and toe counters.
  • Sole is Vibram® AR, Mont compound with a sharp heel brake and mountaineering heel tread for stability, traction and braking.
  • Semi blocked toe, with anti-slip grooves, medial climbing support zone and durable heel edge.
