I've worn Danner boots for around ten years and have been amazed at the comfort and support they provide. Also, the way these things last is unbelievable considering the way I wear them. I've seen some reviews that claim this boot to be narrow but I have not found that to be the case at all and I typically wear a D or Medium width boot. The first pair of these was a little tight but after some wear and breaking in they fit like a glove. That's the key to danner boots.....wear em and break em in......just suffer for a week or so with some sore feet......once you get em broke in, you have something that you'll enjoy putting on every day. I have problems with a lot of boots being too hot but this boot I've found is very comfortable and cool.  Maybe it is due to the cordura mix w leather that allows them to breath a little better.. Love these boots and will wear em til I can't!
