I have super narrow feet, skinny ankles and a higher set calf like yourself and suffered from a similar heel lift issue. I'm downsized to a 26.5 and have owned KR 2's and own a pair of this year's Lupos. Both boots certainly eliminated any heel-lift and I love the way each boot performs. They seem to be the only boot in which i can get that cast-like snuggness I think we all dream of. I would just be careful of calf/shin issues.
With the standard intuition, the top fold can cause a vertical pressure point down the side of the shin, especially with chicken legs. Brilliantly, there is a pretty significant nerve located in the same location. When the pressure from the fold aligns with this nerve, it can cause some pretty obnoxious pain. I've had this issue in both boots, but make the sacrifice for the sake of a static heel. I know someone with KR's who had the same issue and was able to fix it by replacing his wraps with Intuition Pro Tongue liners. I've been meaning to do the same, but don't yet have the disposable income. So yes, I think they could work out really well for you, but be aware of this issue and try em on. And of course, Reputable boot fitters can help you out big time if you're willing to spend the money.
