When I heard that Harald was moving away from foam liners and was skiing an intuition liner I wasn't sure what was going on. I love my Nordica foam liners and I wouldn't trade them for the anything. Since moving back to skiing my Head Raptor Boots I was in need of a foam like liner for my Raptor 150's. They say that the last size is the same between the 130 and the 150 but the 150 is tighter and when I put my foam liners from the 130s in the 150s they are too tight to ski. After talking with Harald and Chris about the intuition Pro Tongues I had a pair shipped to me. My shop in Montana baked them for me and set me up with toe caps and corked up my hot spots. The last 5 minutes of the 15 to mold the liner were as painful as anything I can remember but this is a seriously tight lasted boot. After skiing these two days I can say for sure they are awesome liners. They are firmer than injected foam liners and Harald and Intuition say that they stiffen the boots by 20% or so (not sure how scientific that number is but you can feel the power in this liner). In a tight lasted boot the fit is totally glove like and it feels very similar to injected foam except is a good bit firmer. I can't ski in regular stock liners once I got used to injected foam. This liner rivals injected foam and may actually be better. What I haven't done is to drop this liner in my 130s and see how they feel. Some percentage of what I was feeling power wise was the 150s which are tighter and stiffer. But my sense is that some percentage of the power was also from the liners. If that is the case, they are a strong candidate to replace my injected foam liners in my 130s. I love the 150s but they are real pain to get in and out of unless they are warm. The 130's with the Pro Tongue Liners may be the perfect combo creating a boot that is easy to get in and out of that has darn close to the power of the 150s. Clearly I will do that test my next time on snow.
For anyone looking for new liners, these are awesome and a worthy replacement for the injected foam liners that so many of us have grown to love. I never thought I would find a rival to injected foam liners much less one that might be better. These things rock!!
