Funny that you both ask about the on and off phenomenon. These liners are a traditional lace up liner. In the shop they laced me up and then helped me into the boot and the felt amazingly powerful. Both Harald and Diana ski the liner this way and they are getting into the Raptor 150's not my 130's. So I went home and laced up my liners and spent the next 20 minutes attempting to get them and my foot into the shell with zero success!! I tried again the next night and still could not do it by myself, but with my iwfe helping I was able to. For me this does not cut it. I need to be able to get in and out of my boots solo!! I think we all can relate.
So I have been using the liners without the laces and I can get in pretty easily and getting out hurts some, but I can do it without too much difficulty. Lynn, my approch is to pull the tongue forward hard, and then hold down the back cuff of the liner untiil my heel releases some, and then I set the boot on it's heel with the toes pointing up and quickly take the rest of my foot out.
In answer to your question Gary, yes these liners work fine with my Raptor boots and they work fine with many non Nordica boots.
The cost was $350 which included the fitting.
I am pretty sure that once molded they cannot be remolded.
No they do not breathe with the changes in the size of my feet. They do pack out some over the first 10-15 days of wear. I am about 7-8 days now and they seem about packed out and very comfortable.
Lastly, I spoke with Harald and Diana about how they get in and they spary the inside of the shells with silicone spary. I have not tried this yet, but I iwll in the next few days. It seems like a pretty neat trick!!
