For extended backpacking with heavy loads and summertime mountaineering. Reinforced 3 mm leather provides rugged durability, protection, and extra ankle support. The I.C.E., platform and stretch-gusset upper allow easy forefoot flexibility. The Olympus maintains the sturdy reinforced leather exterior for solid ankle support and foot protection of the popular Moraine, but infuses the design with the versatile I.C.E. technology. The result is a backpacking boot with better flex for easy trail cruising, a more contoured and conforming upper fit, and the ability to climb W14. Swiss Galluser leather upper with laminated PU membrane for added water resistance. I.C.E. platform for integration with either the I.C.E. 9 or Khumbu Crampon. Molded lace and gaiter clips integrate with the I.C.E. 9 or Khumbu crampon. Carbon fiber lasting board for lightness and flex. Hidden stitching for durability.
