They look cozy but are big. My feet are 10 inches long so according to the size chart on the Vibram website I should choose 8.5-9/41 but they are huge. I have about 1/2 inch extra length in front of my big toes and due to the shape of the shoe and the shape of my feet, my little toes barely fit in my pockets. I'll try 40 and see how they fit. As for the shoes themselves, the wool is soft and moderately warm (based on a few minutes of trying them on at home). The soles are made out of a fairly soft material and I'm not sure how durable they'll be, but it looks like they at least give great ground feel. If it weren't for the bad sizing recommendations I would have given this 5 stars.
