The rando-racing and freeride touring hybrid.
At half the weight of a standard AT boot, the La Sportiva Spitfire Alpine Touring Boot is the go-to choice for seasoned ski-mountaineers and touring freeriders who know that speed and efficiency are critical to safety in the mountains. The Spitfire's carbon-fiber-reinforced 'exoskeleton' offers precision and performance during the descent without the need for a stiff, heavy tongue. When the ascent gets rocky and technical, you'll appreciate the EX Flex tongue and the extra-hard edging platforms for secure footholds and the soft rubber under the forefoot and heel for shock absorption.
- GShell, the shortest and most compact shell on the market (measuring a mere 297mm/11.in for size 26.5) is made from the ultra-lightweight nylon polymer Grilamid to reduce thickness and weight without a loss in stiffness or power
- The ultra-light and stiff CRP Cuff is molded with a carbon-reinforced polymer providing a 68-degree range of motion for maximum agility on steep climbs and switchbacks
- Innovative EZ Flex Tongue, made from the tough but lightweight Pebax polymer, offers unrestricted ankle movement for steep ascents and easy walking on flat ground
- Vertebra Technology features a carbon fiber-reinforced exoskeleton that provides maximum security and precision during the descent, eliminating the need for a stiff tongue
- 2BT Tech Last and Heel feature a minimal external volume for reduced weight and an anatomical design that excels on technical terrain
- The thermo-moldable Skimo Liner features a double tension lace system and EZ Flex hinge for unrestricted ankle movement
- Forward lean can be adjusted to 12, 14, or 16 degrees to match your preference and the terrain
- Fast Lock Closure system easily switches between ski and hike modes with the spring loaded Cam Closure System and QuickBuckle
- WarmSole innersole puts a thin, lightweight barrier between you and your cold-conducting plastic soles
- LazerGrip Outsole features extra hard edging platforms for technical rock sections and full rubber coverage for excellent grip in mixed terrain; rockered shape facilitates a natural walking motion
- Low-bulk heel is engineered to provide an easy fit for crampons
- Compatible with all tech-style bindings

Can someone at backcountry test all of your automatic crampons (those with the toe welt bar) and let me know which will fit with this boot?
So far the Grivel G22s do not.
Will be using these for skiiing + ice climbing, so need a solid, aggressive crampon to go with them.
Are you having problems across the front welt? You can try moving it to a different hole or even slightly bend the bail wire.
Also, did you try both sets of bars?
If you could post pics top, front and side, I might be able to help you figure it out.
Yes, see my pic on the G22 product page. I've tried every hole combination, and the best that can happen is that the very sides of the toe welt make contact with the bar. Any input appreciated.
I did just try a BD telemark toe bail at a store, it is more square, which allowed it to make more contact with the toe welt, but it was far too narrow.
If I can't get this to work, I wonder if a custom front bail can be made. That or I could look at getting the new-matic fronts and swapping out whenever I use my ski boots. I really want to make this crampon work.
I posted up some pics and a link for you on the G-22 page, We'll get it figured out eventually.

I can't fit into TLTs because they're too short/narrow. I had the Scarpa F1s, but they were too sloppy and the durability style of fastening was poor IMO. I'm also recovering from an ankle injury so I needed something with a vice-like hold on my foot. These seem to be the ticket. I had to have a boot fitter push out the shell quite a bit next to my pinky toe as my feet are wide there, but after that and molding the liner they fit pretty good. I took them up to camp Muir on Mt. Rainier and they climbed well and provided a night/day level of support over the Scarpas. They were also night/day stiffer than the scarpas. I'm using them with the GT skis. I prefer snowboarding, but I also prefer not carrying heavy equip, and this combo I have now is pretty light (also using the RT bindings).
These boots are rubbing the inside/bottom of my feet, however, and on a longer climb I could see that becoming a debilitating problem. I had a similar problem with the scarpas. I've never had this problem with mountaineering boots, so it must be a ski boot-specific thing. Hopefully the boot fitter has ideas on to fix this. It's as if the floor of the boot was molded to push up on the inner/bottom area for some reason, which I don't like. Other than that they are exactly what I need in order to make mountaineering trips a bit more fun/efficient. Now to get good at skiing again.
Forgot to add, the system of tightening these is also night/day better than the Scarpa F1 (and it appears the alien). You can actually dial in the tightness with the strap, even when walking for added ankle support. The scarpa were either fully locked or fully loose. The lower buckle is also much more durable and and really simple, but nice design that also makes it easy to attach a leash.

I've only skiied these a few times on skinnier skis but they fell great when touring, ski nice and stiff on the down and are really comfy. I had some tlt5's and nothing I did would work, constant pain either in the lateral foot or in the arches, and the carbon cuff typically dug into my calves, I really wanted them to work but it wasn't happening. The spitfires weren't comfy out of the box, I added cork footbeds and had them shaved down a bit, but combined with the really nice stock liners they're coming around to being super comfortable, like any of these lightweight boots these won't be the warmest though they supposedly added some material on the bootboard to increase insulation. If the tlt5's don't work try these!!!
Does anyone have experience with these relative to the TLT 5 performance? They seem like they have similar purposes. The differences appear to be that the spitfire is slightly lighter, without a flex toe, and they seem less cluttered visually. But the TLT has the great reputation of being light AND skis half-decent. Can anyone comment on how the Spitfire skis?
Just skied the Spitfire's for the first time today on a couple groomer laps. They skied great, I was very impressed with the stiffness (all the power I could ask for, even without the booster strap) comfort out of the box (I'd say they have a narrower fit), and buckle system (very easy to change from uphill to downhill - and no need for a booster tongue like the TLT 5's)
Be aware however, that the actual weight of my size 26's is 1160g, or just over 5lbs per pair. I checked with La Sportiva about this, and they revised the weight on their website. Hopefully Backcountry and other retailers will follow suit!
@R Roy: what skis/bindings are you pairing with these boots?
I've only skied them with my lightweight race skis skinning at the ski area so far (no snow in CO to speak of). My backcountry setup is a pair of La Sportiva Lo5 skis.
Looks like the weight comparisons are (size ~27, from web sites):
Dynafit TLT5 Mtn 1225g
TLT5 Mtn TF 1065g
TLT5 Perf 1050g
Sportiva Sidereal 1180g
I think Sportiva has incorrect weights as I believe these are supposed to be lighter than Sidereal.
