I've been wearing Keens H2 shoes for the past three years, and I now own several pairs.  They are so incredibly comfortable and durable.  I like that I can throw them into the washing machine if they get muddy, then put them in the sun to dry.  I've worn them on a number of mission trips to Haiti and the DR, where walking conditions are not the easiest or safest -- so while the web design makes them cooler in hot weather, the covered toes make them safe over rough terrain.
