Thanks for the comments, and interest. These are the "stock" liners from a 2012-2013 Lange WC plug boot. The same shell that all of their race athletes, right up to the WC use. It's a narrow last shell, hence the liner is low volume. If you have a high volume 100mm lasted boot with a big thick liner, I don't see how these could help you. If you're squeezed into a boot of the right length, but the high volume liner is too thick, and you're squeezed too tight, these might be worth a try. I have never heard of anybody using heat on a pair, as I doubt if there's any material in them that would respond better to heat.
My kids were in either a Dobermann, or a Lange "real deal" plug boot, with a lace-up liner, from 2002 on. One of them coaches, and the boot that he wears when he's really skiing, rather than standing around is a Dobermann, with the stock liner. The liners in all of these boots have been improved pretty much every year, while the shells are virtually unchanged. His new Dobermann has actually "returned" to the original 2002 mold and plastic, but the liner is much better. I would say that the Lange liner has moved even further. The original lace-ups were more like a sock, with a barely decent tongue. Much better now. Keep in mind that a plug boot is fitted by modifying the shell……grinding and punching where you need a touch of space. You want to be close to the shell, yet not in pain. Most shells, in my experience, can be modified….even if it's not grinding a thick plug shell.
I've sold a few pairs of these, as my kids would typically have two pairs of boots a season, and might use one pair of liners. We always had extra liners hanging around. My daughter's now in a wider, and softer boot, post race career, with a BD foam liner, so she won't need these….and asked me to sell them. This is less than half of her price, maybe a third factoring the shipping, and her cost was about half of retail…..so I think you could try them in a boot with a minor investment, and if the fit…..great. If not, re-sell?
I do know that everybody that I know who has made this move with a "race" boot….either a 93-95mm plug needing a newer liner, or a 95-98mm shell wanting a different liner, feels that the performance and fit of the latest lace-ups improves the performance of the boot. They are not warm, but they aren't as cold as they were. My daughter trained and did a lot of free skiing at one of the coldest mountains in the country, almost every day for nine seasons, and never wore another liner……so they're very "skiable".
If anybody wants me to actually measure the length of the lining, and the width, height, etc. I can do that later today.
Frankly, I've sold a lot of race and high end gear to fellow ES Bears, and I'm surprised that nobody has picked these up. I have a lot of friends who gripe that if they bought a new, and better liner, they'd save many hundreds on the cost of new boots. I had over 750 days on my last boots, and in the process used 3-4 liners. This is a cheap way to upgrade.
Want to pick them up just north of Boston? $40, if we eliminate shipping. Have a corporate UPS or FedEx account, and want to send me a mailing label instead of my paying for shipping? We can obviously do the same $40.
Hope that somebody can use them.
