Ascendant Touring Ski Boot

The Full Tilt Men's Ascendant Touring Ski Boot might feel light on the uphill, but it's surprisingly aggressive for the downhill. With the removable tongue, this boot boasts a 120 flex—Full Tilt's stiffest—for an aggressive, freeride feel on the downhill. The removable tongue also gives this boot a massive range of motion in walk mode, and it completes the boot's three-piece construction. Three-piece construction amplifies the boot's progressive forward flex for a smoother power transmission, a dynamic rebound, and more excellent shock absorption than ski boots with the standard two-piece construction.

Full Tilt made this boot extremely comfortable for long days in the backcountry. It has a wide 102mm last that leaves plenty of room for your toes to play, or for extra layers on a frigid day. Its Full Tilt Pro liner uses a unique drawstring and J-Bars around the ankles for a locked in fit, and there's a removable pad in the back that increases the boot's forward lean for a more aggressive performance. Underfoot, the Ascendant features a shock absorbing boot board and Michelin rubber with sharp lugs that ensure traction on rocks and ice.

  • Familiarity: I've put it through the wringer

Just want to follow up from my previous review. Turns out Full Tilt offers 12 flex tongues to replace your stock 10 tongues. Now that I'm running those, the boots are brilliant. Hike mode isn't affected enough to put the 10's back in!

If you like Full Tilts, you'll be good.

  • Familiarity: I've put it through the wringer

Although I've fit better in the "classic" Raichle/Full Tilt shell, I got the ascendant to work well without any professional boot modifications, just liner molding. I'm a US shoe 9, and the 27.5 is a comfortable relaxed fit, the 26.5 would have taken some real work to get it to fit, but could have been higher performance fit if I took the effort.

Descending is the typical full tilt feeling, just certainly softer than my "10 flex" tongues on my alpine FT boots. Everything feels great until you're trying to muscle big skis in a skinny chute, or through very heavy snow.

Climbing is good enough on short climbs, and becomes great when you pull the tongues. I'm only pulling tongues for hikes > 1 hour. The buckle latches work fine to keep things loose but not floppy during hike mode.

The boots are very warm, significantly warmer than lighter weight touring boots.

My only gripe is stepping into the Tecton toes. After studying these on the bench, I had to shim a 1mm spacer between the Michelin hiker sole and the boot bottom to give my toe inserts the proper ride height. Toe step in used to be a bitch, but now its almost automatic. Yes 1mm was a world of a difference.

If you like Full Tilts and you want a hike-able boot, you can't really go wrong. If mine get stolen I'll buy another pair immediately.

What I was Looking For

  • Familiarity: I've used it once or twice and have initial impressions

It's a tricky thing these days, finding the right balance between uphill and downhill performance in a touring boot. I'd say my goal was to sacrifice some uphill performance, in exchange for a almost-no-compromise downhill experience. I've only got one real day on these boots so far, but they seem to fit the bill.

Uphill had my the most concerned. I have no interest in removing/installing tongues all day, that is outrageous. However, I bought these based on a theory that the removable tongue is strictly for them to get the marketing hype of massive range of motion figures. I suspected that with the tongue in, but buckles and power strap and full-looseness, I'd still have plenty of range of motion to move around. And in my opinion after one tour is that my theory is correct. I kept the tongues in, and as long as you have the buckles as loose as possible so they don't hold the cuff back, the range of motion is plenty for my usual stride.

On the downhill, I'd say they are indeed the almost-no compromise I was looking for. The flex is great, not super stiff, but it's actually a normal smooth flex since the boot uses the same tongue style as their alpine boots. The two things that irk me slightly and result in some slight compromise, is that the generous high volume fit and low cuff definitely make it a lot less powerful than the normal alpine boots I'm used to. I have a pretty wide foot, but skinnier heel/ankle. My whole foot was swimming in these when I first molded them with no footbeds. I added some footbeds to fill up some volume and re-molded them and that made the fit great almost everywhere, but still lot's of room in the ankle region. Planning to get some jbars to velcro to the ankle region (the liners have velcro in place for you to do this) and I'm somewhat confident that will get me pretty dialed.

All in all, I think this is a great boot for someone looking for something more downhill oriented, but still tolerable on the skin track. If you're used to alpine boots then these will still blow your mind on the uphill in fact. My last touring boot was a Scarpa Maestrale, and I find the slight loss in uphill performance tolerable. And this is referring to tongue-in performance. If you want to remove those things you can crush your buds up the hill with 12ft strides all day.

Update: I didn't even notice, but the boots came with j bars in the box that you can add to the liner for extra ankle/heel hold! Love that they ship these with both the hard plastic soles, soft rubber soles, tools needed to work on them, and the j bars.

Update to my update: Another couple days and they've broken in a bit more and I'm even more stoked on how these ski! For a touring boot, the downhill performance is really really good. I wouldn't even be too mad if I ended up at a resort in this, although I wouldn't make it habit of it just because the thinner touring liner definitely wouldn't have the all-day comfort of a thicker alpine liner.

Also, in addition to leaving your tongue in I personally recommend removing the inner velcro strap that's on the liner. I already removed the drawstring as well. I my opinion you simply don't need that extra complication in your life. That said, that is 100% personal preference so definitely try them out at first as intended by Full Tilt. but be open to modifying them to what you like.

King of the Backcountry

Hell yeah, I love these boots. Sweet gaiter for waterproof ability and unmatched comfort with the wider last. These boots are the ultimate ski machine. They ski extremely well on the downhill and are a great range of motion and comfort on the uphill. With sole inserts included to give you a 2mm shim, and J-Bars for your ankles to add extra heel lock and support. They also come with rockered michelin soles that are extra grippy and make walking all the better in them. I am super satisfied and don't carry the same concern as some of the other reviews with the screws - might just need to do a swap on them.

Good dual purpose boot, but...

  • Familiarity: I've used it once or twice and have initial impressions

Went through trying on a lot of boots and this in a 26.5 with a 301 BSL and 102 last felt the best. I bought the boot knowing that I have some Marker Kingpins that just need to be mounted so you can use both tech and alpine bindings in this boot. Removing the sole, I was pretty disappointed in seeing that only two of the sole holes have metal threaded lugs in the plastic. This means if you plan on removing the soles just once, the holes will be stripped. Just skied them today and already 4 of the screws in the soles are loose. I imagine I'll be bringing these back to Backcountry at the end of the season for them to send out to Full Tilt for warranty, if they make it that long. Why would Full Tilt skimp on a $.01 part that ensures the soles don't come loose! Rather disappointed...

shoot me an email at cekblad@backcountry.com and lets talk about the boots my man.


I would agree that plastic threads require a bit more caution, but I have swapped these soles on mine and all threads are still 100% in tact and snug. They don't require an insane amount of torque so no reason to be stripping them, and metal inserts would just ad unnecessary weight and cost.

Curious if maybe your particular pair got over-torqued at the factory? If you like the boots otherwise don't let it discourage you! Should just be a matter of getting that warranty/repair at the end of the season then you should be good.

My boots had the same problem. Screws stripped right away.


    Believe the hype. First touring boot that didn't tear up my feet on the first few tours. Fit is solid and the walk mech is nice and simple. Not as much motion/freedom as some ultra light options, but this boot actually skis well on the downhill.

    I've been through more than 5 iterations of touring boots in the past decade, and this is the first boot that skis well.
