It's my first shoe made of this material. I find the shoes not as breathable as a shoe leather. So not great for higher temperatures. He is me definitely too hot. But he holds very warm at low temperatures. So from +15 to -10 degrees suited very well. Otherwise, it is very convenient and suitable for longer walks. The heel could be better cushioned. But this bothers below 10 km mileage. Very pleasant is the soft sole, which offers a very pleasant walking comfort. This need not be paid for with high wear due to the Vibram outsole. He falls in size just like Timberland moccasins.
