Bomb omb

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

I have heard a couple people complain about trekkers compared to bindings, but I had no issue with them whatsoever. Being able to use my regular FKS bindings in teh backcountry is nice, even though taking the trekkers out of the bindings is relatively time consuming.

Don't bother.

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

Pony up and spend the money on real AT bindings. Don't try and take the shortcut like I did. When I first got into ATing I tried these out and wasted $150. In the years since I've moved on to dynafit bindings and lighter setups for ski mountaineering, and the correct gear makes all the difference.

These are flimsy and my first time out with these they broke on me. They straight up suck at side-hilling, which you will certainly run into on any backcountry excursion. Couple that with the fact that they add more weight to an already heavy alpine binding, and you've got a recipe for a helluva leg workout going uphill.

If you can afford skins for the backcountry and already have an alpine setup, then you can likely afford day tickets at your local ski resort. That means you can afford real AT bindings. Go buy the real thing. you'll be glad you did.

FKS bindings and 316 BSL

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

So heres my experience with the Trekkers using Rossi FKS bindings: They kind of work. I have a 316 BSL boot.

1. The heel of the boot bangs against the upright heel piece unless the small uphill climbing bar is pushed up. So you are in an uncomfortable forward lean position. OK if you are going uphill. not ok for approaches.

2. I adjusted the hell out of the trekkers to make sure they were super snug in the binding...but they still slipped out of the FKS 3 times total in a 2 hour tour (each side popped out). If your boot is hitting the upright heel piece this would happen constantly.

3. The boot does not engage the brake on the heel piece so you will have to do some sort of modification. I tied the brake together with a piece to rope, which worked fine. This was actually the best part of the various issues with the Trekker/FKS interface.

In summary, I wouldn't buy the trekkers if I was going to use them with FKS. Just too big of a pain in the A$S. maybe if you have a different boot size than me some of these issues won't occur, but with a BSL of 316...they will. If you are on a nice orderly skin track the trekkers may not slip out of the FkS but I was on one with some slick spots that had a side-slope, which puts more pressure on the side retention, esp in the toe. I used my buddies pair of trekkers and I may use them again, but if I was spending my own money I would put it towards something else.

For a certain skinner

  • Familiarity: I've put it through the wringer

I will start by saying if you are looking to spend an entire winter skinning exclusively, these are not for you.

If you are however someone, like me, who gets out in the backcountry fairly often, but need something more bomber than a touring specific binding for the way down, look no further.

I used my first pair for about 4 years before eventually breaking one. I would say that is not half bad. Yes, they are heavier than a tech binding, but no, I wouldn't want to send a booter or a cliff on a tech binding.

The proper tool if you want to go up the mountain and be able to come down in your reliable, bomber alpine bindings.

For a certain skinner

They work fine. The only thing that isn't great is that the trekker doesn't push on the brake so it never fully comes up. I just wrapped some tape around the middle bad of the trekker so that when clicked in to my FKS the tape you push on the brake pulling them up.

hey John, did you have an issue with the trekker banging against the upright portion of the FKS heelpiece like in the video posted by matt on this page?

It seems like if the climbing bar is up that may help, but also would be pretty uncomfortable on flat terrain.

Love these things

  • Familiarity: I've put it through the wringer

The Alpine Trekker for me is a tool I use almost everyday when going in the backcountry, even if on a snowmobile. I love the trekker because it gives you a quick way to turn your skis into touring skis, without the hassle of having a touring binding where you have to worry about bindings icing up and not being able to lock them from touring mode to ski mode. Or having the AFD plate snap off rendering one ski useless. With the Trekker you always get where you want to go, and once at the top have a solid reliable binding. I've done everything from 10 min skins, to a 6 hour approach from hut to hut in Argentina on these things.


  • Familiarity: I've used it several times

Not really what you want to take into the backcountry but works well for basic things. I use it to skin up easy slopes or after the mountains close for the season.

They'll get you up there...

  • Familiarity: I've put it through the wringer

I've been on the same pair of trekkers for a few seasons now and they are still holding up. Though they aren't quite as convenient as today's AT bindings, they will get you to the top and then you have the reward of shredding your line in your trusty alpine bindings. They may be a little outdated, but if you're primarily doing short tours or sidecountry shred, they will get it done. There's a reason they aren't extinct...


  • Familiarity: I've put it through the wringer

What a disappointment. Every time i have gone out with these something on them has broken. I picked up a pair of these to just mess around and see if i was going to like alpine touring and all they have done has made me frustrated. I have just been going in the hills around Pittsburgh and thankfully that is as far as i have gone because i have had to walk part of every trip. I managed to find a pair on sale for $75 and now i know why. Save the money and get a real pair of bindings.

Great Beginner Binding

  • Familiarity: I've put it through the wringer

I have used these for a few seasons now and have been a great alternative compared to buying a more expensive tour binding. I got these on Ebay for $50, well worth it. I have had the back plastic piece break on me which is inconvenient, but not a deal breaker. I have also had them popping out of my bindings when turning or putting a lot of pressure from the side, which isn't always a consistent thing. Take note mine are an older model.

I don't regret getting these.

They are what they are...

  • Familiarity: I've put it through the wringer

I have had a pair of these for about 4 years now (too broke for touring bindings) and they have always worked fine. They have the most issues side-hilling, as they do not have the best torsional rigidity. Sometimes they can be a bit funky on kick turns as well. I lost one screw from mine, and once I realized this decided to epoxy them all in place. I can never adjust them from a 28.5, but the chances of them falling apart on me have been drastically reduced. It is nice to take these off and step into a 16 DIN alpine binding for the way down. These are a great option if you do not have the money to invest in a pair of touring bindings or are just starting to get into AT. With a little care they will take you a long way...

It should be noted that they do not work super well with FKS bindings, the turntable heel does not allow them to go fully down, so it is kind of like walking with the riser up all the time. They seem to work the best with Salomon STH type bindings, or the Atomic version, or anything with a similar heel piece.

Great entry point

  • Familiarity: I've put it through the wringer

My first foray into the BC was on a early pair of these decades ago. 1/2 Pricey now compared to Dynafits Speeds. But for anyone wanting to try it out in the BC on Alpine boots/bindings you shouldn't hesitate. I used these for a week at Rogers Pass in Salomon alpine boots and bindings and and never knew the difference. The fun was on the down anyway. Easy jump into the BC fun!

Trekkers In a Marker Binding

Take care of them, they take care of you

  • Familiarity: I've put it through the wringer

My first day on these was a disaster. One broke after 20m of skinning. I kept going with just one. Then that one broke a few hours later. I have since got them dialed to work very well. Here is what you do. First thing before anything is DON'T USE THEM IN LOOK/ROSSIGNOL BINDINGS. They are amazing in marker jesters. Second. Before your first tour glue the front screws that hold the pivot point in. I cannot imagine why you would ever need to take this off. So I JB welded mine on. This is what broke 20m into my first tour and I lost the screw. In the 3 years since I have glued them they have worked fine. Also extent the part that goes into the binding as big as you can still fit it in so that it pushes the heel peice back so you don't hit it with the heel of your boot when you step down. So they work, kinda. Just keep an eye one them. Tour with duct tape, extra screws, and super glue. And they will be just fine

Hi step,

Because of the way the toe piece is shaped when you stride forward the toe of your boot hits the toe piece and torques the whole trekker in the binding. for me this meant after an hour and half of skinning the part of the trekker that goes into the binding had twisted so that it would not stay in the binding and kept releasing. I now used them with a pair of jesters and they work perfectly. I'll try to post a photo in a few days so you can see

If you can't afford a whole new binding

  • Familiarity: I've put it through the wringer

I have toured on these for a couple seasons (someday I'll be able to afford a touring binding) and they get the job done as long as you're careful with them. They are not going to kick turn like an alpine touring binding will so be careful on those switchback skin tracks. All in all though, they have got me where I wanted to go.

My recommendation would be to make them slightly larger than they need to be so that the binding will lock them in real tight.

Day Wreckers,...

  • Familiarity: I've used it several times

These were good back in the 90's, they way out of date know, spend your more more wisely. If you want something get Marker or Salomon Guardians. If you want your DAY WRECKED buy these, if you want the ability to do some skinning/touring get Dukes or Guardians. If you want to get serious get a Dynafit setup. I have not used these in over seven year, but I still remember how badly they sucked.

So wait, you recommend that instead of spending ~$150 for a binding adapter, someone should buy at least a ~$450 binding? Plus the new boots that fit into that style binding (~$500-700).... Might as well get new skis, too at around $500-700. So spend $150 to see if you even like AT or spend $1000-1400 to see if you like AT.


  • Familiarity: I've used it several times

I bought these to use for a 3 day backcountry class and I wasn't sure that I wanted to invest heavily in new gear for (potentially) a single trip. Reading through the other reviews, I can just as easily apply the positives and negatives to my experience. Set up was easy and pretty intuitive. Traveling on flats or directly up the fall line was easy enough, but traversing and side stepping were very difficult. There was too much play between the boot-trekker-binding to set a really solid edge with them on.

They pack up nice and small. They're not as light as a rando set up, but skis, bindings, trekkers were lighter than a friend's designated backcountry set up.

My biggest problem wasn't with the trekkers directly, but with the stiffness of my boots and the inability to really flex forward onto my toes for a more natural gate.

So, just to be clear, one purchase of $179.95 includes two binding adapters, correct?

I have a pair of Look Pivot bindings mounted currently. Will these slip out of the heel because they are able to pivot? I really like the bindings I currently have but still would like touring ability!

Actually if you check out John Kutcher's picture in his review, you can see that the middle guy (possibly Kutch?) is using his trekkers with a pair of Rossignol FKS bindings - exactly the same binding as the Look Pivot, just a different (BRIGHT orange) paint job.
