For cold sensation: I now had a 2-hour exit at about 8 °. Initially there was sunshine, as they were quite warm and I felt like in warm moon boots (with the exception of freedom of movement, of course, you feel almost no difference whether one has now the shoe or not. After about 30-45 minutes the sun was off but it was still OK. Only in the last 20 minutes it was a little cold in the toes, but it's manageable and few degrees less are there certainly still splashing around.
