These boots need very little break-in time and can be laced up walk miles from day 1. They are waterproof and very supportive. I guide big game and upland, these boots you can walk for miles inn and not get fatigued. Not really anything to dislike about 'em. To me they seem to be more flexible than kenetrek, not as rigid and stiff in comparison. Been very happy with my purchase since 4 years ago.
