After sking on my Zipfit Gara LV for about 40 days I added 4 tubes of composite (2 to each boot) to the tongue, also over top and sides of forefoot. Tweeked to fit better, dont know of any other liner that you can do that wirh. Love my liners, always have had problems with boot fit, not anymore. Easy to do with youtube instructions.

awesome stuff, works well, zipfits are the best

I typically wait longer than I should to recork, partly because they are rarely in stock. So I end up having to use more than one tube of cork for just one liner, and I'm not enjoying spending so much per tube. I have to recork every 3-4 weeks with daily skiing as a ski instructor. I wish there was a way to buy more cork in bulk, and that it was more available because I love my zipfits.

The cork works very well. Excellent product!

Works well as designed. Zipfit ski boot liners are the best aftermarket ski boot liner you can purchase. They have worked great for over 5 years and counting.

OMfit Cork Flow tube does what it says it will do. Can require quite a bit of force to get the plunger to move, once the tube is almost empty. But really nice to be able to adjust the fit of my liners.

It was nice to be able to buy an extra tube of OMfit cork to be able to dial in my liner fit exactly. I started with the two tube kit with the plunger and found I needed just a bit more. This single tube did the trick.

I've skied - ski touring mostly - in my Zip Fit liners 40+ days this season. Adding cork as needed has been fantastic. It takes several days to "dial in" the need to add cork, but it has been easy to install and works well.

I'm very happy with this product! I also appreciate all the wonderful Youtube informational videos! I have very challenging feet and lower legs to try and fit into a ski boot, and this cork product and system has given me NEW hope that I can enjoy the sport that I love and enjoy comfort at the same time! Thanks Team Zipfit!

Very easy to use to dial in the Zipfit fit.

Works great. You don't need as much cork as you think in my experience. Play around with what works for you though. The customer service is excellent. If you need help give them a call or email, they will sort you out.

works like a champ; added cork in the lower tongue area to reduce heel lift

Great but need much additional cork

Package open on arrival. No tube

Easy to use and tightened the liners up to be very comfortable

I recommend having these cork fillers on hand to experiment with dialing-in your liners. In my case, I used several tubes and learned how the system works. Love my liners, they really do improve fit and performance, even race boots.

Looking for that foam filled perfect fit. Shop doesn’t install enough Cork. After an expensive liner we continue to buy more cork for that right fit. The liner not warm. Now have frost bite on my toe .

Perfect for tweaking the fit
