These are very comfortable  well cushioned with a good arch and a snug heel that doesnt slip.  As they are Gore-Tex, I can wear them in any weather and they stay dry.  My feet are on the slim side of M but I need a roomy toe box, and these don't pinch my toes.  My normal size for boots is 9M (usually 8.5 for shoes) and 40 fits well with light to medium socks.  The fabric back makes them lighter than all-leather boots, so they are good for travel.
