I decided to start a new thread regarding life expectancy of boot liners.
What are your thoughts? What liners have you found to be the most durable?
Since the ski boot liner has a finite life span (about 25-40 days), it is essential to not accelerate this process at all. In a bootfit, make sure you are using as thin a sock as possible.
Using a padded sock for the fit process kills the liner and can cause sheer if you are not putting your boots on properly. Padded socks have their place, but it is far more limited than you think. The additional material is usually found on heel, shin. Sometimes, I see socks with padding under the metatarsal heads- that's Neuroma waiting to happen! Shear in a ski boot cannot be underestimated.
Wow, informative, thanks. you said a liner may be dead after 40 days. I often put 400 days on a liner, hmmm. still learning. how about replacing the liner with intuition or other after market? can that liner be used in future with any boot of same bsl? is there a process to refit the liner to a new boot, after having fit it to the old boot? what liners do you like? I'd like warmth into the deal. what is the life expectancy of an intuition or comparable liner?
Yeah, stock liners don't hold up well under the daily pressures of industrial skiing. Guys (and gals) skiing every day have special needs. Among the most important are control and comfort. After finding the correct shell for their foot shape, many industrial skiers toss a stock liner and start with an Intuition liner from day one.
It is generally recognized that a strong skier will power through a stock liner in a couple of weeks. However, some stock liners are very durable and solid.
I thought this was just considered a normal part of the packing out process and is why many serious skiers want something that is a bit too tight initially that then fits them "perfectly" days ~15 to 200+ (with the counter being the myriad of skiers who say their boot fit fine in the shop and their first couple of ski trips, but now feels loose).
Your liner life expectancy comment has got me thinking http://www.epicski.com/t/109432/lange-banshee-and-wc-120-advice#post_1420796
You mentioned sock padding being a bad thing. I use the Smartwool racer socks which is a thin sock with a little padding on the shin. What is your opinion of them?
By the way, my usual course is to get the boots fit with my thinnest ski socks, a Smartwool utrathin I think. Stick with the ultra thins for probably 20-30 days on a new boot and then move into the racers as the liner gets a little looser. The final step as I approach 100 days is to move up to the thicker ski socks, Thorlo etc. that I bought a long time ago before I became as serious about snug boots. I also use very thin liner as one of my criteria in boot selection.
Practically speaking this seems like a good approach for those who want to balance good skiing with real life economics.
