Welcome to the work bench

We explain this here, but basically the key is to warm the shells and liners so that the OMfit cork becomes easily malleable and takes the shape of your foot and lower leg once the the foot is in the liner and the liner in the shells.

To learn more about adding more cork, visit our Home Fit page.

ZipFit liners come in half sizes ranging from 21.5 to 31.5. Typically, we advise skiers to choose the liner that corresponds to their ski boot shell size, or if the ski boot brand uses whole sizes, size down a half size (24.5 ZipFit in a 25 shell).

There are some exceptions, notably when skiers have down sized their shells aggressively (2 or 3 sizes smaller than their shoe size) — here we advise trying on a few different sizes for fit and comfort. Because ZipFits have a flexible neoprene toe box, we advise ensuring that the volume and fit of the instep and cuff are secure and proper, and if you can size up your liner to have more comfort in the toe box, your toes will thank you.

If there is a local ski shop that carries ZipFit, we recommend going in and supporting that shop. Professional boot fitters can help you with far more than just your Zips and they will help with any uncertainty you have around at home fitting.

If your local shop doesn’t have the ZipFit model you want, let us know and we can set up an arrangement to get that style liner to the shop for you.

If there is no shop nearby, we will gladly help you select the correct fit for your feet and ski boots. We are committed to customer service and are here for any questions you have.

We field this question a lot. It all comes down to user preference.

Are you willing to lace up your liners and step into your shells before every use? Our leather lined ZipFits require this move, while our neoprene lined ZipFits are easier to step into. If your answer is “no way” – we suggest the neoprene liners.

Leather offers a true to form fit meaning your ankles and shinbone will imprint into the leather, securing your lower leg and foot to the ultimate degree.

Neoprene has more natural cushioning, so while you can still get an excellent fit, they have a more forgiving feel when skiing.

Both interior liners can last a LONG TIME with proper care. While we think of leather as more durable, we know of a pair of neoprene liners with 1500 ski days.

For precision fit and performance, the leather has a slight advantage.
For ease of use and all mountain comfort, the neoprene has a slight edge.

ZipFits position your foot correctly so that your ski boots don’t cut off circulation to your feet, this is the single best thing you can do to keep your feet and toes warm. Additionally, ZipFits feature a toe box constructed of neoprene, merino wool, and Thinsulate making for a far warmer fit that conventional foam liners. Neoprene naturally insulates, which is why surfers in the cold northern Atlantic use thick neoprene wetsuits. Pairing neoprene with thermoregulating merino wool and Thinsulate provide warmth without too much thickness, keeping your feet toasty without impacting your stability or reaction time.

Ski boot liners will dry better if removed from the shells, but what about the wear and tear of removing the liners and then stepping back into the shells? We recommend removing your ZipFits from the shell after skiing to unlace them and let them dry and then using the Ski Boot Horn to assist in stepping back into your shells. The Ski Boot Horn dramatically reduces the wear on the backs of your liners and by lacing your liners up prior to stepping into your boots will ensure that your foot is properly positioned.

The Gara Stealth is now the Gara LV. We wanted to add a high volume Gara to our line up for skiers who want a stiffer cuff but need to fill more space. The volume of the Gara LV is the exact same as the previous Gara Stealth, we just added the LV to distinguish from the HV version.

Certainly, but take note that if you make an incision in your liners for boot heaters, that will void your 30 day money back guarantee. We recommend skiing in your liners for a week or so to ensure they are the right size and model before you add boot heaters.

If you want the option to customize the amount of OMFit cork fill in your liners, you’ll want to order the OMFit Kit that comes with two tubes of cork and a plunger to inject the cork into one of the ports. There are three ports on each liner, one in the tongue, and one that accesses each ankle pocket. See our fitting instructions for adding more cork. You should only order single tubes of cork if you already have ordered the OMFit kit or you have access to one of our plungers. The tolerance is very tight and finding a substitute to our plunger won’t be easy.

ZipFit liners often last skiers between 300-5oo days on snow. Foam liners in comparison pack out after 30-50 days of use. Foam and cork composite are dramatically different in structure and composition. ZipFit Liners are constructed with cork composite and cork doesn’t pack out or compress, so it remains the same volume over time. The cork composite material, paired with durable microfiber and neoprene make ZipFits last much longer. Our customers routinely get over 500, 750, even 1500 days in a single pair of liners, read through our testimonials and reviews to learn more.

Intuition liners are the industry standard, there is no doubt about that. ZipFits are far beyond standard. Unlike the Ultralon foam that Intuition liners use, ZipFit’s OMFit cork composite material does not compress, meaning no packed out liners. What’s more? You can add more cork to dial in your perfect fit, and since ZipFits can outlast your shells, you can easily re-warm your ZipFits to make sure they fit perfectly in your new shells as well.

Remolding: If you mold an Ultralon liner to fit a 3 piece Dalbello, and then try to remold it to fit a conventional Tecnica, that liner will not rebound and form to your new shells – you will clearly see the lump of foam over the instep from where it molded to the Dalbellos. As foam ages, it stiffens, and folks who’ve tried skiing hundreds of days in foam liners will tell you, the liners begin to crack as the foam degrades. ZipFit liners are constructed with highly durable microfiber, leather, and neoprene, and then filled with our proprietary cork composite. They remain supple, pliable, and if you re-warm them, the cork will migrate toward the areas where you need to fill volume. No cracking, no packing out, and no shrinking or changing shape.

Talk to someone who has skied in both, they will break it down for you. ZipFit Liners break in while other liners break down.

Yes, we highly recommend using a good over the counter orthotic or custom foot bed in your ZipFits. ZipFits are designed to keep your foot and leg in the proper position within a boot, having the correct footbed for you will help immensely. If you are interested in ZipFit footbeds, reach out to us in the Contact Us form.


There are times when it is totally acceptable to blame the gear, because a lot of ski boot liners… suck.

That said, if you buy ZipFits and you aren’t automatically the best skier on the mountain, don’t blame the gear, blame the skier.

Our laces and power straps help keep your foot in the proper position and enable more power transfer through your leg to your ski. If you don’t want to use them, that is totally acceptable. The power straps and laces are removable.

We sell replacement power straps on our website. If you need replacement laces, reach out to us in the Contact Us form and we can help you out.

At this point, we have heard that ZipFits are not compatible with most snowboarding boots, however, we have heard your cries for a better snowboarding liner and we have a project in the pipeline.

Alpine snowboarders have had great success with ZipFits and we suggest you check out this forum for more beta on liner choice.

We haven’t personally used Apex Ski Boots, but if you buy a pair of ZipFits as replacement liners, we recommend using them inside the Walkable Boot and not directly in the Open Chassis shell. If your ZipFits are not compatible, return them within 30 days for your money back.
