I spend a lot of time on my feet, and these are some of the most comfortable, sturdy, well made boots I have ever used.  Great grip, not too heavy. My feet don't get hot even in the summer. Last pair stood up to 2 years of almost everyday use. The soles wore out due to some use on concrete, but the uppers were still almost perfect. Gore tex alllows easy washing off of mud,etc without having to wait for them to dry.  Very well padded comfort right out of the box. On my second pair now and I hope they keep making these.
