Description

At 1 pound, 8 ounces per boot (size 27), the Alien 1.0 is the randonee racer’s choice, and the majority of skiers standing on the podium in Ski Mountaineering races are skiing this boot. The 1.0 is also the first ski boot in the world to use the Boa® Closure System on the exterior of the ski boot. This on-the-fly speed dial closure technology is extremely light, and offers very quick adjustment and a glove-like fit for top performance, comfort and speed in a variety of conditions—up and down. Other features include a carbon-fiber upper cuff, and a unique lower-boot construction made with polyamide on the exterior and a carbon-fiber internal core, which provides a rigid but more agile-performance over all-carbon construction, yet still keeps the boot very light. The “A-Light” quick-release walk/ski mode lever is very precise, easy to use, super light, and ultra-quick to transition between ski/walk modes.

Sizing

SCARPA Sizing Chart

Measure your foot with a ruler, using cm or inches; convert to Euro or US using this chart. If you need mondo sizing, please refer to the SCARPA chart on this page/tab. We recommend you purchase two sizes, the size you think you are plus one .5 size bigger for fit testing at home. As long as the products are in like new condition and the packaging is 100% intact, we will credit you for the returned product.

General fitting rules depend on the product's intended use... follow the appropriate guidelines below for best results.

Trail/mountain/approach/lifestyle products:

  • The bigger/heavier/more supportive the product, the more you may want to upsize .5 - 1full size. Lighter, softer, more supple shoes can be sized closer to your measured size.
  • Note: SCARPA Plastic mountain boots all use UK sizing; UK converts easily: 1 full size smaller than US men's size, 2 sizes smaller than US women's size.
  • Try on with appropriate socks for your usage. The bigger the boot, the more appropriate a bigger sock (sounds crazy, huh?)
  • If you use orthotics or already have aftermarket footbeds, measure against the standard footbed in boot. Fit into boot for sizing/fitting the boot.
  • Best to try on at the end of the day when your feet are larger/swollen, than when your feet are fresh to ensure good fit after a long day.
  • Lacing can play an incredibly important part of a good fit. Be sure to play with lacing when analyzing fit.
  • Make sure your heel isn't slipping.
  • Make sure your toes aren't hitting the end.

**Approach shoes may be sized smaller for performance purposes but beware... small shoes are really uncomfortable on the trail.

Rock climbing shoes

  • From your measured size, you'll want to consider downsizing .5 - 2 full sizes. The flatter the shoe, the closer to your measured size; the more downturned/aggressive the shoe, the more you'll want to downsize.
  • The best fit is comparative between sizes and only you will be able to judge that, though an experience climber could offer good insights to your fit.
  • If it feels painful, it may break in... or it may not.
  • Pain sucks as a rule of thumb though and makes climbing miserable.
  • Only you can judge what's 'acceptable' discomfort.
  • Good fitting rock shoes shouldn't necessarily be 'comfortable' by walking/running shoe standards.
  • Look for looseness/bagginess in the toes and heel. Bagginess can mean 'slop' when climbing with feet perspiring, etc.
  • Toes should completely fill the toebox.
  • Heel should feel solid; like they won't pull off if heel hooking.
  • Any foot movement in new shoes will mean sloppy fit when broken in.

Ski boots

  • From your measured foot, convert to US size using the scale. Translate the US size to Mondo size using the SCARPA mondo scale (not 'true' mondo conversion)
  • Shell fit: taking liner out of the shell and inserting foot, toes touching end of shell but completely flat.
  • Should have 1.5 - 2 fingers of space behind heel and heel of shell (between 14mm - 20mm)
  • Too little space = go up one shell
  • Too much space = go down one shell
  • If not sure... fit test BOTH shell sizes
  • Put on a ski sock for gosh sake!
  • Use and orthotic? Put it the boot (after taking out the standard footbed).
  • Put foot in boot AND BUCKLE IT! You can not tell a boot fit without buckling it
  • This will pull your heel back into the heel pocket, relieving cramped toe space
  • Boots do pack out! A 'comfy' fit when new will mean slop later.
  • Regardless, your toes should NOT be pressed against the end of the liner
  • Get your Intuition liners molded! This provides THE BEST FIT available.
  • Any minor pressure points or space will be eliminated by molding
  • Find an experience SCARPA dealer for fitting/molding
  • Boot fitting is an incredible service and generally requires a service fee of varying amounts... it's worth it though!

    At this price these boots better hike up the hill all by themselves! And they are so light that they feel like they do. I thought there would be no way that they could ski well, but they actually do with a skinny ski at least. I bought them for some skimo races and mainly for long technical traverses. I've had them out for several trial runs and been very impressed. FIT- Luckily I tried them on and went one full size larger than I normally wear. I'm usually a 28 and I fit nicely into the 29's. They are slim fitting like Scarpa tends to be. So far I haven't put in an insole and they feel great. My guess is I'll go without for racing and put some in for comfort on really long outings. BOA- They use a boa system to tighten the lower part of the boot. It works fine. For speed it seems like you don't want to play around with this much. Just find a tension that works and stick with it. If you pop the plug then they loosen up a ton and you'll take some time tightening it back down. UPPER CUFF- This is a pretty slick system that tightens the cuff and engages/disengages the walk mode all in one move. This takes some fiddling to get the cord at the right length. Too tight and it's very difficult to flip the latch into place. And too loose your boots aren't snug for the downhill. I find that leaning forward helps decrease the leverage and make it easier to engage. ROM- The range of motion for touring on these is incredible. I have hiking boots that feel more restrictive. They honestly feel like tennis shoes. DOWNHILL- They will ski! I'm driving small sticks, but they don't feel like fruit boots. I'm really surprised they can get that sort of performance out of that lightweight of boot. COLOR- Wow they stand out. DURABILITY- They seem really well built and much more sturdy than I was expecting.

    I have had 6 different pairs of ski mountaineering race boots, and these boots have definitely taken performance to a new level. This is the first boot I have had that not only allows complete freedom of movement in walk mode, but also allows you to confidently ski, skis that are much bigger than skimo race skis. I have been very impressed by the durability of these boots. Previous to these I raced in the Dynafit DyNA. The DyNA developed significant play in its rivets after only a few weeks of use. After 3 months of heavy use my Alien 1.0s have developed no play and still ski as well as they did on day 1. I always use either the gaiter or a race suit with a built in gaiter when skiing or skinning with this boot in soft snow.
