The key to custom fit:

The secret sauce to ZipFit cork ski boot liners, our proprietary OMfit cork flow composite.

  • Two tubes of the OMfit cork flow composite and one ZipFit plunger.
  • Used to make fit corrections where more volume fill is needed in the ankles, heels or tongue areas.
  • Two tubes is normally more than sufficient for a single pair of liners.

About cork ski boot liners:

Here’s a visualization: Throw a cork at the ground and what happens? It bounces back. Throw a piece of EVA foam at the ground. What happens? The impact is dampened and then there is a sad piece of foam on the ground. Beyond being a natural regenerative material, cork is incredibly responsive and has higher ductile strength and ductility than foam.

What’s this mean? It means that the energy you put into your turn actually transfers from your leg into your ski, instead of being lost to compacted foam. #foamisdead

Custom fit:

Custom Fit?
If you get new shells, you can remold your ZipFits and add/remove cork as needed. None of this “custom fit one and done foam injection” – we encourage you to tweak with your liners and make sure they are performing and comfortable. If you have any questions about caring for your liners so they last you the next decade, check out our Warranty and Care Instructions.

    I got some new shells this season (moving from a Lange XT3 110 22.5 to an Atomic Hawx Ultra 115 23.5) and needed to take out some volume. The OMFit Cork Flow Composite Kit is easy to use at home and do yourself. I used one tube per liner, splitting it three ways to add room in either side and to the instep. My Atomics are fitting perfectly now after a few days on the hill to finish molding to my foot. This is why love zipfits so much, they easily transfer from shell to shell and complete the fit.

    Coming from Nordica Doberman Race Liner, my expectations for the highest level of fit and performance was quite high !!! I would consider myself a “Boot Nerd”. With included plunger and tubes of cork I was able to add more cork to the tongue. Resolving a fit issue I’ve had for years!! The liner is also far superior in lateral transmission to the boot and edge. Thankfully, liners are well worth the investment. I also, received helpful and personal CS from the owner!! :+1:

    I’ve skied in these for years. I teach skiing and I need a boot that fits well and is warm. I have a long, narrow foot and I’ve tried custom liners (others are too flimsy), foam liners (too hard and cold) and plug boots (also too cold). Zip Fit liners keep my feet warm, they are responsive and my foot stays in place. I can add cork as needed, exactly where I need it to go.
    My liners live in a lightly heated boot bag overnight and are put on while warm and malleable in the morning. There’s no better way to start the ski day!

    Easy to use. Awesome to have this available.

    can’t say im impressed with this “Plunger”
    you could probably just find a stick and buy two extra tubes of cork
