Merrell makes a lot of shoes, but the Outland is my choice.  They are robust, easy to break in, and very comfortable.  In particular, they are very stable and sure-footed, with a very grippy sole and a comfortable lining.  My orthodic insole easily replaces the one provided, there is plenty of "toe room, and I can spend long hours on hard surfaces with these shoes better than any others I have tried.  In general, it is wise to order a half size lager than you usually buy, as Merrell's tend to fun a bit small.  Best shoes for comfort, stability and long wear that I have found.  And I've tried many!
