No, they do not. I had a pair of Intuition liners fitted for Alphas, but found they were too bulky around the ankle, which I didn't like. I returned the Alphas, and used the liners in my ski boots.
I also found that "sizing down" didn't apply to Alphas, because they are already a very low volume boot compared to something like the Inverno.
In case anyone is interested, here are some gory details and pics from someone (not me) who has used Alphas with Intution lines.
good stuff
