Keeping warm on Mount McKinley (Denali) ’the coldest mountain in the world’. A quick look at my feet, from my socks through to my crampons. La Sportiva Spantiks, 40 Below Purple Haze, Grivel G12 Newmatics. Comfortable and easy to manage in very cold weather - more practical than other 8000m options. Should return with 10 toes.
