I have the KR Core 2 and they are an amazing pair of boots that fit me really well and are very comfortable at the same time, the only thing I would recommend is that you change the Dalbello stock power strap with a booster strap as that thing is like having your shins hit a brick wall.
Other than that they are the best thing ever and look the shit too although that doesnt really count for much i suppose.
You'll have a blast on them.
