So, we baked a pair of Pro Tongue liners I had leftover from a pair of boots I unsuccesfully tried to fill the voids in, and they are TIGHT in the ZJ
But the Pro Tongue cuffs are too thick and push my knees way too far forward, which I wasn't feeling with the stock liners. Plus the liners themselves are extremely stiff and uncomfortable, so I have some Race FX on the way which are supposed to be softer and lower volume. The stock liners are, as you know, like a few sheets of paper thick and don't take up enough volume.
That being said, holy cow am I excited. My instep/ankle area is so close to the sides of these boots. They don't feel stupid stiff indoors, but my understanding is they will change quite a bit out in the cold. But, that can be dealt with. So, we'll see how soon I can get them put together and out on the snow. I usually don't like skiing my boots without canting, but I'll take them for a spin just to see how they feel.
