Comparing siblings is a no-no in the world of good parenting. It's not right to define one (especially the younger) by traits of the big bro which he lacks. But these aren’t our kids and these siblings are ski boots so we're gonna do it here. K2’s Pinnacle 110 HV is slightly shorter, slightly chubbier and slightly softer that the 130 version. Sorry dude, that's life. But hey, at $100 less, you are a much more affordable kid to raise. Who doesn’t like that?
The point is that the 110 HV doesn't really lack much that the 130 offers other than some macho-man stiffness and that hook thing on the Powerbuckle power strap (which is a nice touch). This is a kick ass boot for any good skier who has an average to somewhat wider foot and doesn't have the weight or ego issues that demand a 130 flex. The 110's cuff rides a touch lower on the leg, testers felt, so it's a particularly good match for shorter and younger skiers or guys with thicker calves that don't like a tall cuff climbing up their leg.
The LuxFit Tour Intuition liner is softer than the denser 130 model, giving the 110 more of a relaxed comfort feel during initial try-on. It doesn’t mean it’s any less fierce on-snow. The 110 HV turns it on with the pent up rage of a pissed-off younger brother and matched the bigger boys turn-for-turn.
