Liner Stretching

post #1 of 20
Thread Starter 
Anyone have any ideas on how to stretch a liner? I'd like to have more room in the toe box area.

Your liner will compress but there are a few things you can do... first would be a custom foot bed from a good ski shop ...did you try raising or lowering food bed.Depending on boot you may pick up some room that way ...last thing you want to do is blow your boot...post boot manufacturer and model and you will get better info

I ski a Head RS100 and my boots have already been ground and stretched. I've got 50 days on the boots already. These are beefy liners. I've already got custom footbeds. I just want to stretch the toe box area of the liner a bit.

Thanks for the links. I didn't find them in my previous search. Just what I was looking for.

The heads have notoriously viscious small liners so the instructions on what to do there should help you a ton.

L7, are the cuts absolutely necessary or can I heat the liner up good, beat the crap out of it with a mallet to soften it up, and then stretch it with a boot stretcher?

There are lots of ways to skin the cat in liner stretching. I usually use the superfoot hydraulic strtcher and heat the metal ram hot enough that it almost sizzles spit. Then when the liner is pushed out, to the desired length or shape, let it cool, and the liner will hold the new shape. If a different shape is required, I use one of several wood blocks that I have ground to various shapes. The wood blocks won't hold much heat, so in that case, I heat slowly from the outside.


Short liners have been endemic with Lange for years. In an earlier life, I spent some years placing size 9 race liners in size 8 boots and doing a toe-ectomy too. That is however, typically a race dept practice and not generally practical for retailers.

It really depends how much stretch you're looking for. I don't find those heads have much give since they're kind of burly but you could try your suggestion and go to sierra jim's next and see if either of those are enough. As for the wood blocks SJ is speaking of, I like to use hockey pucks cut into shapes. Potato potahto but pucks are cheap and easy to work with and have that pre made round shape.

If you need lots of stretch the cuts gets you tons and I trust you realize the rubber rand goes back over and seals it as long as you have a decent footbed over top you'll never know the cuts are there.

When i first saw the the title of this thread i thought about one thing: a neoprene toebox. Usually higher end models have it. So if you could get a liner w/ a neoprene toebox that would be great. But i think that you don't want to do that. Another thing you could do is replace the material in the toebox with neoprene. I think this can be difficult to do but if you can find someone to help you it would be great. To be honest it makes a world of difference. I put the Dobermann lace-up flow liner w/ neoprene toebox in my XTs and the difference was amazing. The standard liner (which i do not like) does not have it.

A key point no one seems to have addressed is cutting the rand (bottom of the liner) off from the front of the toes about 2-4 inches back towards the rear of the foot. This will allow the toes to splay and lets the liner stretch easier. Plus most of the time the rands run up the toes, making a boot shorter as well.

Apparently it's not so easy to find hockey pucks in Cali.

L7,

If you want length and width spread evenly across the toebox would you cut a cross in the bottom of the liner?
post #15 of 20
Yep, I've done exactly that many times.

L7, I'm having a heck of a time getting these Head liners to move much. I'm getting maybe 1/16" between the slits. I've tried shoving my foot in there with extra socks and tissue but that only got me width. I've also got a boot strectcher that one uses to stretch leather boots and that is great for width as well but I'm having a tough time getting length. Any ideas?

Make sure the slits you are cutting are long enough. Your foot probably won't do it with those head liners so stick to the stretcher. You don't want to cut the slits all the way to the stitching on either side but as close as you can without it giving away. I have gone right past the stitching by times but it's not the first choice at all.

I've tried different approaches including heating them up but getting them to stretch in length is tough. They are truly a burly liner! I've got the width I want but still not the length. I may just give up and do a toe-ectomy.
