This is my third pair of Keens.  They are so comfortable  right out of the box.  These are VERY sturdy yet I like the vented sides so they don't get hot.  I prefer the lower profile for comfort and flexibility, but that's a personal choice.  The sizing seems to run slightly large but that leaves room for some extra thick socks.  I have got them wet a couple of times and just wipe them dry.  I am very happy with my shoes.  When it comes to hiking shoes, I will always buy Keens
