Before leaving to climb in the Himalayas my biggest concern was how to keep warm. I get cold easily and particularly my feet tend to suffer. My toes turn into ice cubes and no amount of wiggling them around will get them back to life. I don’t only get cold feet, but I also have rather tiny feet. Which meant my options for high altitude boots were limited. In fact, there was exactly one shoe that came in my size, the La Sportiva Spantik.
