Zipfit Grand Fuckin’ Teton Liner

[skibrd]

If they are 560g for a 27.5, (Im a 26.5 so shave off a few grams) I’ll be getting a pair in my next touring boots.

Mine arrived too, 475g in a 24.5. 460g after removing the upper strap, which in my experience isn't useful. These are going into a pair of TLT8 Carbonios - 1359g total including shells, Zips and custom footbeds. This is highly acceptable, even if I need to add more cork later.

It was a tight fit, but I was able to get the liners into my shells with the help of Zipfit's nifty $10 boot horn (any thin sheet of semi-rigid plastic could be fashioned into a similar device). Initial impressions based on carpet testing... yeah, these are legit. Super secure fit, heels absolutely locked in, but plenty of room in the toe box - a hair more than with MV Intuition Pro Tours. I haven't even molded these yet but they already feel incredible. The ROM feels like less than the Pro Tours, but still quite good - just a little bit of extra resistance in the last 25% of the flex in either direction.

More to come after getting these on snow.

Curious for updates after some miles.
My experience of skinning in regular zipfits was that the cork migrated around behind the ankle bone and kind of messed with my fit until I skied for a bit and it migrated back. Hopefully this has been resolved in the GFT.
Probably not something I’d personally stick in a lightweight all-day boot but for the right application nothing else skis like a zipfit.

Agree re comparisons to the pro tour mv. Much more secure heel fit, more room in the toes (in a good way i think), and a bit less ROM but significantly better than a stock Gara.

25.5, 502g, fit awesome, stoked to ski them tomorrow in some ZGTPs!

Interesting. I’ve never had this happen while skinning in my Zipfit freerides, but I’ll keep an eye out for it with the GFTs.

I won’t be using these for long traverses, but for any tours that involve significant skiing, I think the performance benefits will be worth the weight penalty.

Well..........................any beta?

I took mine for a 2-hour tour today. The fit is incredible. Perfectly uniform pressure over my entire lower leg and ankle, with enough room to wiggle the toes. In tour mode, this translates into a comfortably snug fit with no hot spots or pressure points. The ROM is closer to the Pro Tours than I expected (at least I didn't notice a huge difference, although I didn't A/B them with one liner on each foot). Flipping into ski mode locks your feet into the boots like they're encased in concrete. Zero play or heel lift. So far, these liners are exactly what I was hoping they would be. Any remaining deficiencies in my skiing can only be blamed on technique.

Caveat: this is all based on a single short tour.

Some context - I have these in a pair of TLT8 Carbonios with a 1 finger shell fit. I have wide feet and low-volume ankles, and I've always struggled with heel hold, especially in touring boots. The other issue I often run into is that I have big upper calves and get calf cramps when I tighten the top buckles. For me and my specific issues, the GFTs (and the Freeride liners in my inbounds boots) provided a complete fix after years of experimenting with other liners, footbeds, extra padding, etc. YMMV.

Also - after molding the liners, I added 1/2 tube of OMfit to each tongue bladder, and 1/4 tube to the left ankle bladder, then remolded them by warming in the oven at 200F. Highly recommend ordering a couple of tubes of OMfit along with the liners in case there's any extra space that needs to be taken up.

I just moulded mine. I used 12mm diameter wooden dowel to inject the OMfit cork - Worked perfectly, so there’s no reason to buy the proprietary Zipfit plunger.

For my skinny legs and low instep I found that I needed to add 1.5 tubes of OMfit to each tongue to make the GFT liners fit like my Zipfit Freerides.

I've had a bunch more days on the GFTs now, including a few longer (6-7hr) tours.

THE GOOD
- The overall fit/heel hold is comparable to my alpine setup (Hawx Prime + Zip Freerides) and blows every other touring liner I've skied out of the water. Super locked in from the lower shin through the midfoot, and comfortably snug in the toe box and upper cuff.
- No blisters or hot spots - this is a side effect of the above.
- No signs of cork migration within the liner after prolonged skinning.
- ROM is really quite good. The limiting factor is likely to be your touring boot rather than the liner.

THE BAD
- Heavy (twice the weight of an Intuition MV Pro Tour)
- Somewhat cold, and definitely colder than Intuitions, although this may be due partly to the tighter fit. That said, I've used them down to -18C/0F and haven't lost any toes.

OVERALL
- By far the best touring liner I've ever used in terms of downhill performance, with minimal compromise in weight, ROM and warmth.

I don’t want to go touring in less then -18C/0F so these sound like a winner to me.

How much cork are you guys adding? I bought only two tubes thinking it would be plenty, but with my skinny legs I've already added a full tube to each tongue. It feels like the factory configuration barely has any cork in the two ankle bellows, but my ankle hold is already phenomenal, so I'm not sure how much I should dare to add there.

[mr_pretzel]

Sounds like you should also add a spoiler for your calves. In my opinion the cork in the tongue hangs out on the instep.

I added no cork to mine for xt3/zerog/mindbender130 and I usually ski a lange ZB with a older gara

I have really skinny ankles, actually from the bottom of my calf muscle down is really skinny. My boot guy added a spoiler to my boots behind my Corsica 92s to take up room. It’s slightly a pair to remember to put them in every time because I have to take my Zipfits out of my shell to get them off, but I put the spoiler back in the shell and it hasn’t been a huge issue.

Yes, I already added a cope spoiler to the liner as an interim measure, but I figured perhaps it would be better to add more cork instead since it will shape to my leg as I ski. Sounds like you guys use the spoiler as a permanent measure and the bootfitter(s) recommend this?



Full Tilt spoiler wedges pretty okay behind the strap. And yes, before you bully me, I mostly keep the liners in the shell. I know, not the Zipfit philosophy..

There is essentially only cork around the ankle, achilles and in the tongue. i find cork in the tongue bladder tends to hang out over the instep, not up high where you are trying to take up space.

tucking a spoiler where you have it is exactly what most bootfitters would do and should be a permanent solution if you're alright with the increased forward lean.

finally, i highly recommend you don the liners first and then slip them into the shells. you're not doing any favors to the cork by leaving them in the shells and shoving your feet into them.

Hmm.. at risk of asking a stupid question.. how come? I don't understand why it makes a difference..

Screws up the heel pocket by pushing cork down into the heel pocket requiring skiing time to remold each session.

Much easier to don boots with the liner on anyway

You’ll have a lot of wear and tear on the tongue if you leave the liner in the boot and as others have mentioned, it’s just easier to slip your foot into your boot with the liner on.

We'll see, I tried doing it the "zipfit way" in the beginning but I quickly started wearing the heel out. I've fashioned a homemade boot horn now, so we'll see if that stops the heel from getting torn up. If the heel keeps tearing I'll have to keep the liners in the shell either way.

I use them with a cabrio boot, so entering the liner while in the shell is actually super easy on these.

A strip of gorilla tape down the rear of the cuff and some gaffing tape on the zipfits solves the heel wear issue. some people like adding a spray lubricant for extra glide.
boot horn also works, particularly if the cuff isn't particularly smooth (see salomon xmax)
it's a known issue with a simple fix.

in other news, i finally got my GFTs.
loving the extra forefoot room in ZGTPs and pleasantly surprised by the amount of cork they come with stock.
will update once i've skied them a couple times.

the tape works really well. I also put them on while standing up. Sitting and trying to push in seems to hang the heel up more. Zipfit didn’t advise spraying anything as lube, and said to use a boot horn if there were problems getting in.

Just ordered a pair of 29.5 GFTs for my 28.5 Hawx XTDs. This gives me hope that I made the right call.
