Aveolite foam insulation provides the maximum protection for climbs in the coldest regions on Earth - like Antarctica, the Himal and Alaska. The warmth adds up - the K2 Inner Boot boasts 7mm of insulating foam, the soft flex Pebax shell incorporates another 6mm plus the outer gaiter has an additional 2mm overlay on the lower boot - for a total of 15mm of thermal distance and insulation from the cold. This year the EVEREST is lighter than ever - with a new midsole and full service Vibram Marmolada outsole for durability and maximum hiking and climbing efficiency.
Have faith - we've been fitting this boot for 20 years... and don't be confused by all the sizing numbers on the boots or box. It works like this: if you wear a sz US 10.5 running shoe (brannock size) order 1 1/2 size number up to an EVEREST 12 US. This assures a good fit and allows for swelling at altitude without compromising your circulation. For sizing US 9 running shoe (and under) size up 1 full size. Fit guaranteed with a faxed tracing of your bare foot and sizing history accompanied by order faxed to 831 620 0977!
