I skied today and unfortunately the Speedmachine 12 boots are so roomy in the forefoot that I was floating in my liners. Thank god the cuff and heel were clamped down, so I could still ski well. After several hours I had to conclude that these liners were made for a much tighter boot. But the liner is incredibly hard and precise. Instant feedback from the slightest movement. The Intuition Gold is really a race type liner, made for a narrow, low volume boot. I could not bend my boots at all, which was OK in high speed carves, but I think it would be murder in bumps.
I went to see the boot fitter and he agreed that if I have that much room, the liner will simply not expand to take that space. He suggested to go to a size 27 Silver Intuition liner (my Gold liner was 26.5).
After the process I had a MUCH tighter fit and I will see how this plays out tomorrow. If this does not work, I might consider lifting the zeppa or even purchasing a lower volume boot. But I think it will be fine, since the liner felt really tight in the shop. We'll see.
