I'm very happy with these so far, they are warm and waterproof, give enough support and are great for me as someone with wider feet, usually I wear size 11 shoes so for these a size 13 was perfect. They are also a good in between if you don't need anything super technical but still want good boots for glaciers and rocky trails, they are comfortable enough I could wear them just for a pretty casual hike.
