It took a couple of runs for the shoe to break in and for my foot to get used to it. Now, after 200+ miles, I love it. I have flat feet, wide fore-feet, narrow heels, and multiple skier bone-spurs.
The sole is stiff, nearly like a hiking boot; this is a plus for me. I have weak, skinny ankles, and the stiff sole to support my feet and ankles wonderfully. I also have weird, narrow heels, and I have not gotten heel blisters from these guys. After long runs, 12+ miles, I have gotten toe blisters, but thats also been the case with every other shoe I have worn.
I like the lacing system and overlap system; my only complaint is that it doesn't go down quite low enough over the forefoot.
For as burly as it is, I find it lighter than my UltraRaptors.
Great shoe, and I imagine that is partly because I have a weird foot and they fit me.
