If I were to get new liners (Intuition) for my well adjusted and well fitting boots (thanks Jeff Bokum), would it affect their performance? I will be using the same footbeds also. I think I may be getting a slight bit of pack-out, but the boots still fit and work great. There is a slight bit of extra wiggle room (not much though) and I wonder if there is a shorter lifespan for a liner than a shell. I seem to read lots of good things about Intuition.
