Very comfortable,  I have only worn a few days but they are more plush than the keens I have worn.  The footbed is very cushioned and feels a bit like rolling over the bumps.  The sole looks a bit large in some views but when worn it appears pretty normal to me.  The BOA lace system is excellent.  I have always had issues with Keen laces loosening up during wear but these clamp precise and stay there.  I hope they wear as well as they currently feel but will update if that changes.  I would really like to try more of the BOA lace system and need to explore who else produces shoes with them.  I usually wear a size 11  however these required a 11.5 to get the fit expected.  Subtle issue but easily fixed with an exchange.
