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.
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.
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!
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.
Has anyone had the leather upper rip. Mine ripped when the zipper froze and i pulled the liner out of the boot which resulted in a large tear and de-lam. Kind of a bummer as it's now a matter of time before the upper is useless, tried to glue it but it just takes too much pressure when the liner comes out.
Hi SVH, you should not force the liner out without unzipping the cover (which is not leather). We tell customers to zip up without the velcro attached to avoid unnecessary strain on the cover. Sportiva warranty covers problems not due to abuse.
thanks for the response jbo, the zipper was frozen solid so i couldn't unzip it, not necessarily looking for a warranty though. do you have any advice on how to repair so that the entire upper doesn't rip off? gorilla glue and duct tape failed pretty quickly.
Sorry Sean, haven't had to try yet. I've been babying mine.
yes, i've had little rips on mine but likely because when removing my foot from the boot (liner still on), i forget to pull off the velcro first. it was a learning curve after years of pulling my foot out while leaving the liner in...
I'm still trying to figure out why you moved away!
I guess this isn't the place for the reason, but think........endless new outdoor opportunity (skiing, hiking, fishing, rafting, packrafting) with nobody around, true wilderness that doesn't exist in the lower 48, anywhere. You're it. You, the bears, the fish, and the mountains. Silence...........
