takes a while, but then super warm to hot, especially in cold churches on stones where else to cool down to the bone recommended. Keep 5h very warm and then a few hours warm to lukewarm. Have then put me in the soles of the socks 2, so they do not slip, worked out after they had slipped the first time, just as in the shoe, since they, shoe size 44 is too small for me. Nevertheless, the feet were very warm. However, one should not go up with the soles Mountain. When I had to do with me almost the soles are burned ... after a while on cold stone we went again. If you keep your feet nice and quiet or just as time runs through the Church, really recommendable.
