After reading the reviews I decided to go for these boots even though I was warned of the difficult on/off.  I have very narrow feet and was willing to give them a try, especially at a great price!  I ordered the Slate Black/Rust in a size 11.  I was pleased with the typical Keen construction and the outsole was very rugged looking.  The leather is soft but substantial.  I put these on/off about 4 times, each time getting easier, so they definitely do 'break in'.  Once on they fit a bit too loose unless I had my thickest winter sock.  This presented a bit of a problem because these boots are WARM on their own and after about just 5 minutes my feet were just way too hot.  Perfect for outdoors but not perfect when I am going to be wearing the boots to work, shopping, etc.  Not going to be practical to wear such a heavy sock in and anything looser makes my feet slip around inside too much.  Bummer because they are versatile boots at a great price.
