I got a new set of liners last week after my Dalbello ID Gold's packed out. This time I decided to to with the Dalbello ID Thermo Pro. This liner is a lot like the ID Gold but they are somewhat thicker and are made of a higher density foam than the ID Gold liner. I was hoping that this would be a higher performance liner that would result in a more supportive and stiffer boot - and that is what they did. The liner is quite stiff and firm and it really supports the foot very well. One nice detail is that there are no seams in the forefoot area over the toes across the nail/flesh zone - I found that in the days after molding these seams can sometimes cause some irritation if they rub over your toes. A word to the wise though: they are dense, and if you downsize your boots (as I do) you want to be very proactive about padding out your forefoot and toes with a bit of extra width/toe room or you might end up suffering. I had to mold mine twice before I got it right.
Great liner - warm, supportive and easy to get in and out of. They sell them at the Starting Gate in VT.
