Good Fit & Seem to breathe very well (especially for a waterproof sneaker). I think they are comfortable initially, but seem to get better after a few days. I have plantar fasciitis in one foot tho and after a 9hr day on my feet I can really feel it so I think I'll add a more supportive insole. I would def recommend these shoes so far tho. As with any sneaker/shoe, time will tell if they were worth the $  UPDATE: FEW WEEKS  & THEY ARE BAD. Haven't even gone on a hike with these &#34;rugged&#34; shoes yet.  After breaking them in around the yard and wearing them casually for a few weeks, the different rubbers on the sole are separating. I can feel the tear opening & closing and hear the sound of the 2 different rubbers opening & closing against each other.  I am attempting to contact keen to see if they will offer a solution.  UPDATE2:  KEEN sent me a credit to their site to order another pair of shoes and the replacements I went with are much more rugged and have held up well.  Customer Service was/is great and I have bought more Keen products since
