I will let it go, but you should probably stop citing me. The point about using running as the point of reference is because it is actually the "best case scenario" on this issue. In other words, if it costs 1% more energy per 100 gram of shoe for running, it will be worse in hockey due to dynamic nature of the activity and the anaerobic nature of the metabolism involved. It may not be perceivable, but the effect will be there, and more evident in the 3rd rather than the 1st period since glycogen is exponentially depleted and the primary fuel source for the activity. SVH didn't cite his original research. Saying something is inconsequential doesn't make it so without evidence. Further, if SVH wants to comment on his original research, that is fine, but I suspect he didn't model the effects of increased weight over the course of a full hockey game. All the aforementioned being said, don't get me wrong, I have Makos and will not go back to my Tones because of the superior fit regardless of the weight. At the same time, with comparable fit, reduced weight, especially on the skate (compared to relatively static equipment on other parts of the body) will make a difference. I will also be interested in the VH skates when they are available and despite the fact I like my Makos will likely still want to give them a try. The fit on the Makos will be difficult to beat though, so, other things like weight and "comfort" will likely be important factors to consider.
