The updated version of the Sideral boot provides 2.0 times the refinement. La Sportiva borrowed its slick Pegasus buckles from the Spectre to refine the lower buckle closure. A new lower-shell mold has a refined shape, allowing more feet to fit in. Sportive also added new S3 Inserts™ that refine the compatibility. Now you can step into frame bindings, tech bindings, and even the Trab TR2 binding with the same boot. The Sideral 2.0 keeps the most functional parts of the previous version, including the LazerGrip soles, Fast Lock closure system, and lightweight Tour liners. The blend of old and new make for an even better all-around ski mountaineering and touring boot that is light enough to race in recreationally. The Sideral 2.0 is made in Italy, a country shaped like a boot which thusly knows how to make good ones.

  • Vertebra Technology™ provides a stiff link from the cuff to lower shell for good performance.
  • Cam Closure System™ is a one-motion ski/walk transition protected from snow by a window.
  • LazerGrip™ by Davos soles have excellent traction and hardened rubber in high-wear areas.
  • WarmSoles™ are removable polyurethane inserts that insulate your feet from the snow.
  • Compatible with tech (aka Dynafit), frame (aka step-in), and TR2 (aka cool) bindings.
  • Grilamid® lower shell and PA12 nylon upper are a good combo of lightweight performance.
  • Pegasus buckles let you fine-tune the lower shell fit to get you heel seated securely.
  • Forward lean is adjustable between three positions so you can adapt the boot to your style.
  • EZ Thermo™ touring liners are lightweight and can be molded with heat or just some skiing.
  • New lower shell mold has less rocker so as to fit more feet and crampons.

Question from Dane H
I am planning on using these with a pair of Icelantic Keeper skny 184's (90mm waist) and the trab TR2 as a do everything package. Is this a wise move for on piste skiing? Coming from a ~100 flex (6 tongue) Full tilt that feels plenty stiff to me am I in for a rude awakening? most of the touring I plan to do involves a lot of low angle rolling terrain so the long rearward rotation of a 2 buckle boot seems very desirable, but I do not have a feel for what this actually will cost in downhill performance.
Answer from eric
Dane H, We still have not received our sideral 2.0. If the boot keeps the same flex as the 1.0 (which it is supposed to) I would think it would not be a rude awakening but still it will be a bit softer than your current Full Tilts. In soft snow and rolling terrain I would not see a problem with this boot. Charging in or out of bounds might be a bit soft, if your worried you could go with the Spitfire 2.0 which would be as stiff as your current boots. And its in stock now.
Answer from Dane H
So far have only skied inbounds but I can say that they ski plenty strong for me. Very happy with the boot!

Answer this question:

Question from Martin

Could you explain which boots are competitors with others? e.g. is the TLT6 performance directly compared with the Sidereal 2.0, etc...? What does the Spectre compare with. It seems like Dynafit, La Sportive and Scarpa should all have a few categories that they compete in. Just wondering which boots go up against what....
Answer from jbo
Hi Martin, yeah it would be easier if there were clear categories. We generally classify these as light 2-buckle touring boots with excellent articulation and easy transitions, joining the TLT6 Mountain, SCARPA F1 Evo (currently on hold), and Atomic Backland. Some of these have a "performance" versions that have material upgrades but are otherwise the same design. That would included the Spitfire and TLT6 Performance. Then there is a somewhat big gap in terms of weight and efficiency till you get into boots like the Spectre, Khion, and Maestrale, which tend to be a touch stiffer and wider. Hope this clears it up a bit.

Question from Dane
Renderings are all blue, but photos/videos of samples look purple. Any way to determine what the official color is? Comment from Sportiva?
Answer from jbo
Hi Dane, good eye. I can't verify in person yet since these haven't been shipped. However after asking around, I just updated our main image to what should be the production color: a more primary blue. The back and front views aren't available in that color yet unfortunately.
