This could be the one. The skimo race boot that you wouldn’t hesitate to use on your other adventures. Borrowing features from their award winning Stratos line of world cup race boots, La Sportiva has made the most complete and affordable race boot yet. With full coverage liner zips, a proven single-throw buckle system, durable soles, and amazing race weight, the Syborg (not Cyborg) boot could be the new standard in tour-able race boots.

The 75 degree range of motion is more than your ankle has, making this the leader in striding efficiency. The CavoBike lever is taken directly from the Cube and offers reliable one-motion transitions. The overlapping cuff and ratcheting lower buckle secure you nicely for the down. The zippered liner cover keeps the snow out while booting, and the LazerGrip sole (borrowed from the Spitfire/Sideral/Starlet) is touring ready. A 100.4mm last makes the Syborg comfortable for all day affairs. We can’t think of anything La Sportiva left out. Can you?

  • Carbon-reinforced Grilamid® cuff is a unique combination of stiffness and lightness.
  • LazerGrip2™ sole is borrowed from La Sportiva’s touring boots to provide durable grip.
  • Optional power strap can be used for aggressive skiing or removed to save grams for a race.
  • 35 degree backward and 40 degree forward range of motion is like not wearing a boot.
  • Syborg EZ Thermo™ liner (119g) is designed to take advantage of the range of motion with flexible ankles.
  • Forward lean is adjustable with four different options to choose from: 14°, 16°, 18°, or 20°.
  • Lower “spider” buckles secure the Grilamid shell and lock your heel into place, preventing blisters.
  • CavoBike lever provides effortless switching between ski/walk modes and won’t snag your pants.
  • Ample 100.4mm forefoot width handles more than just skinny feet and keeps your blood flowing.
  • Included optional insert plugs rear "Sportiva gap" to prevent snow from attacking your achilles.

Question from Jim Morgan
 
I am currently skiing the TLT 5’s in a 27.0. What size Syborg would be equal to the dynamite boot?
1/16/2018
Answer from Trace Leches
 
Hey Jim! Depends on how your TLT5 fits and which version you have! There are some liner discrepancies between different models, boot history will come into account, and the sizing on this Syborg throws things off a touch. Fill out our boot fitter if you'd like to dive into a bit more detail with it!

Hi,

This is part review, part question.

Firstly, I've just realised that these huge vert. numbers people are posting are in feet! Us Europeans think in meters, so I was a bit intimidated!

I've had these boots 2 seasons, and for my feet they're by far the most comfortable ski boots I've tried. I have skinny ankles so I have some movement there, but I wear chubby ankle socks and that seems to do the trick.

I'll try not to repeat what's been commented before. Here's some of my experiences.
I use the grivel haute route crampons, and they work fine with these boots. I have the walk/ski locking mechanism adjusted to maximum out when in walk mode and I've never felt it catch.

I try to take as much care as I can when putting on/off the boots but, nevertheless, the leather upper and zip thing do take a beating. Both boots have about 1cm tears at the top rivet, and the zip on one of the boots is detached a bit.
I find that the velcro doesn't stay in place and I get snow collecting between the leather upper and the boot liner. Especially in races with fast transitions, the leather just flops out and then snow bundles in.

The boot liners are comfortable and warm, they've worn against the pivot rivets, so I need to patch them up. I find it takes a fair bit of effort to enter the boot with the liners on, but the boot seems to survive.

I've found the lower buckle is fragile, catching it on a rock can be curtains. I've bent two, and replaced them. I've also found the catch mechanism weak. Often it just releases to a looser position during the day/race.

I have the "new" blocking rod on the ski/walk lever to prevent it going up. I had this fitted after I accidentally caught the lever with a carabiner while putting away my via ferrata gear during a race! I decided to just finish the race with the boot loose which was a bad idea!

I have two problems with the ski/walk lever. One is that it seems to have stiffened; when I try to put it in to ski mode it doesn't spring in anymore without a helping hand. Any suggestions on how to fix that? I'll try some lube first.
Secondly, the little hook collects snow/ice, and ices up preventing it from locking. Both of these problems, particularly the last, have given me very stressful transitions in races. In my last race it was the main reason I lost a place.

The little metal hook holding the red heel flap in place has broken on one of my boots. I must have also once caught the red flap when putting the boot on, as it's bent a bit. Is it possible to get a replacement heel flap with metal hook?

Overall I find the boots ok - the most important thing is that boots are comfortable. Due to my weird feet most boots leave me in total agony, almost crying in pain and frustration. These are the only ones I've found so far that are comfortable. This is a heavy plus. The ski/walk locking mechanism is a heavy minus. The fact I sometimes have to spend a minute or so at transitions poking ice out of the hook is not good. Also, the leaver sticks out, and I'm waiting for the moment where I catch it on a rock and break it. The front buckle also doesn't hold the ratchet in well which isn't ideal either, but I have such a high arch my foot is snug enough.

If I can find an alternative that is comfortable, I'll probably switch, but here in Norway there's no skimo.co - gear selection is limited and tech knowledge is average, so until something changes I'll stick with these.

Hi Robert, thanks for the feedback. It seems like more and more boots are using the external bar-latch for the ski/walk mode lever. All of them can ice up, especially when booting. We just use Whippets or Scrapers to clean 'em out. Also, you can try and adjust the tension on the Cavo lever to see if that helps with the locking. It's also possible the springs have been stretched out due to impact on the lever. You may be able to get a new set of levers from Sportiva. We can probably dig up a replacement red flap for you.

Hi, thanks for the comments. I'll experiment with the scraper on my next outing. I sprayed some WD-40 on the lever and it loosened up nicely, so maybe that solved it for now.

I've messaged you in the contact form about the red flap.

My set-up is almost identical to Colin's (Hagan Y-drive skis with Dynafit Speed Turn bindings). My impressions are similar to Colin's too but I've used the boots longer so wanted to give a durability evaluation. I'm not a racer. I'd say I'm a moderate ski tourer so wanted to give a review from this viewpoint. I'm neither young nor particularly strong and a very moderate skier but these boots allowed me to summit and ski quite a few mountains and keep up with much stronger people! So definitely a game changer for me.

Durability: Resort skinning and touring for two seasons in WA, CO, and New England. Well over 200K vertical and also quite a bit of hiking miles. Skied a few 14ers and a bunch of 13ers in CO, Baker and Shuksan in WA in these boots. The boots are still in pretty good shape. So far, the only obvious damage is to the gaiters. They started to rip near the rivet attachment. Zippers also started to separate on one gaiter so I had to fix it some thread and needle. The design and materials for those gaiters are not great. It but the design is weak. I think it can be repaired using some fabric patches and glue but I'm lazy and it does not really affect the performance. The liners show the use but no actual damage and still quite usable.

Comfort/Usability: Never had a blister even though my typical skinning session at the local ski resort is 8K vertical. I did not mold the liners. I like the cords system for adjusting the rigidity of the upper and find it easy to use. The ski/walk mechanism is amazingly easy to operate. On the flat downhill sections I often switch the modes on the fly without stopping to make things easier. However, when cold I at times I had some difficulties when locking in a ski mode due to icing of the hook. Similar to Colin, I like the red piece near the heel which keeps snow out works and I never had a problem with it as long as I was careful putting the boots on in the beginning.

Ski: I don't think I can contribute much on this topic as I haven't had enough experience with other types of boots for a proper comparison. I agree with what other reviewers said.

Skinning: Enough said, pretty awesome. I want to add that I liked to hike in them just fine, felt light and agile. On the snow it felt like the best footwear period, way better than regular plastic climbing boots.

Crampon fit: As was mentioned in the previous reviews, these will not fit your regular automatic crampons. My solution was a taking rear and upper parts from different crampons accumulated in my basement and coming up with a combination that fits perfectly. Not a solution for everybody but worked very well for me.

Overall: I would definitely buy these again. I think you have to realize what they are, and ski them in all conditions

I wanted to review these boots from a viewpoint of a moderate ski tourer. I'm not a racer, not an endurance athlete, not particularly strong guy. I've used these boots a lot, probably well over 200,000K vertical now. Resort skinning and touring for two seasons in WA, CO, and New England. To give you an idea, I've skied a few 14ers and a bunch of 13ers in CO, Baker and Shuksan in WA in these boots. Frankly, I doubt that I could get up those mountains in heavier boots! So basically,

This was my first foray into a lightweight boot, before this I was touring in a pebax 4 buckle beast. I have used these for a full season, in all conditions, for slightly over 100,000 earned. I have never raced on them, though I might next year. I should say that I skied a Hagan Y-Drive with Dynafit Low Tech's.

Durability: I have had no issues. You do have to be very careful putting these on or you might very well break the zipper (this is not the best design). I don't really tension the buckle across the forefoot, so that was never an issue. And the red piece near the heel which keeps snow out works, some people have really disliked this - just put your thumb on it when you are putting your foot in, I have never had a problem with it.

Ski: Conditions dependent. I mean they are not my Lange RS130s. For me, I had to adopt a much more neutral stance, and frankly - ski better. They are not fun in breakable crust (but what is), on chopped up snow they require vigilance, they would be totally fine on groomer, and they do great in all densities of fresh snow.

Skinning: Pretty awesome. If you haven't skinned in a 'race-boot', it's kind of a game changer. For those that have, I really like throwing just one buckle, the range of motion is really good, and with the gaiter I don't have to worry about snow coming in. Also, with the range of motion I have never felt the need for a higher riser than the low-tech heel, even on stupid steep skin tracks.

Overall: I would definitely buy these again. I think you have to realize what they are, and ski them in all conditions.

Question from Mike
 
Are these officially compatible with Speed Radicals? They seem to be a little sticky when exiting the toes from ski mode.

Answer from jbo
 
Hi Mike, yes they are compatible. Note it's not unusual to want to remove a bit of rubber from soles for the smoothest operation using various boot/binding combos.

Question from alex
 
I want a light boot for long days and ski mountaineering. I love the sportiva spitfire, but am thinking about going lighter in my next 2-buckle. Two quick questions:

1) How do you think the Syborg would hold-up in a mountaineering setting? (mostly I am worried about durability)

2) How does the fit compare to the Spitfire?
2/5/2017
Answer from jbo
 
Hi Alex, lots of folks are mountaineering in race boots, including the Syborg. Like any sufficiently complex equipment, they occasionally have problems that need fixing. The foot shape is similar to the Spitfire, though the lengths are a bit different, owing to the shell break being on the half-size versus the whole-size. I'm a 27.5 in the Spitfire and 28.0 in the Syborg.

I'm a long time skinner (~60 days/yr), but new to racing. I bought these late last season (sz 28.5).

Despite their flimsy look, they ski great and tour even better. But today, after about 25 days on them, the lower plastic buckle snapped off. Really disappointing. It wasn't ratcheted too tight, just snapped in half on the uphill after 2 laps.

Something more durable is needed.

Hi Brent, La Sportiva will warranty that for you. I'd reach out to your dealer for an exchange.

Question from Patrick
 
I'm trying to narrow down what size boot to get. This will be my first skimo racing boot. I wear a 26.5 for the scarpa maestrale and they are comfortable and perhaps a tad roomy. Should I go to a 26.0 for the Syborg? Thanks!
9/15/2016
Answer from jbo
 
Hi Patrick, these are a touch shorter than a Maestrale in the same size, so I wouldn't go down. Especially since 26.0 is a whole shell size (1cm in length) smaller.

These are my first pair of race boots, so I don't have any specifics comparing them to other boots in this category. I'm 6'5" 190lbs and I was skeptical of how flimsy they seemed out of the box, but when I took them out for their first tour I was blown away by how well they ski.

I've used them on race skis, as well as some Dynastar Mythics, and some Dynafit Carbonio 74s. For a race boot they are fantastic, and they work well with the Carbonios. I'm looking forward to using the Carbonio + Syborg combo for spring skiing objectives. I've skied the Mythics with the Syborg and a Dynafit Titan. The Titan definitely drives the ski a little better, but the weight advantage and comfort of the Syborg on the up is more than worth the trade off.

For waterfall ice, i'd say up to WI4 there's not much difference between these and an ice climbing specific boot. My boot size is 30.0 and I've been using a Black Diamond Cyborg crampon. This combo works fine, and there's no interference between the boot latch and the crampon latch.

As an added bonus, driving in your ski boots has never been easier! I will likely buy another pair when these wear out.
