SCARPA Sizing Chart
P2P Bent Gate
P2P Mountain Equipment Coop
  • Designed for people who like to drive big skis or charge hard in the backcountry, the Maestrale RS bridges the gap between alpine touring and freeride skiing. The lightest 120 flex ski boots in the world, this boots offers a walk mode with nearly 40 degrees of cuff travel, which makes them tour exceptionally well. At the top of the climb, however, switch them to ski mode and the Maestrale RS provides a shocking level of downhill performance, given that they tip the scales at 3lbs 7oz per boot (size 27). Details include SCARPA’s innovative Axial Alpine tongue design, polyamide construction, which yields the stiff flex, oversize, easy-to-use buckles, Dynafit Quick step in® tech fittings and a high-performance SCARPA Intuition® liner.

    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!

      Wow... these boots are the BEST, LIGHTEST, MOST COMFORTABLE, MOST TECHNICAL boot I've ever owned and I've owned a lot of ski boots. This boot on my BD Havoc skis makes for a super lightweight package of ski/ dyna fit binding and boot. Just a one handed easy to tote, superlative ski outfit. I recommend these RS boots. You can drive your skis just perfectly with these babies and they are LIGHT, LITE, NOT HEAVY. Did I say comfortable, the walking mode at the resort has people convinced on riding a snowboard... So take my advice, 50 plus years in the ski and climbing worlds. This RS boot is the key to happiness in the alpine world either on the couch or off piste.

      Simply my favorite ski boot: ever. I have worn a lot of different boots, including several from Scarpa, and the Mastrale RS is the best performing boot I have worn for both the up and down. Super light and with a huge cuff articulation, it tours like a dream and allows even the weak to haul a big ski up the hill. When it is time to lock them down the boot drives a fat ski easily and has a very predictable and progressive flex that makes it easy to “flow” in and out of the turns. Because of the flex characteristics of this boot, I actually prefer it to a bigger, stiffer boot even on steep terrain with fat skis. For that reason I have been skiing inbounds with these as well as in the backcountry. Do yourself a favor and check these out.

      I skied the orange Maestrale last two years and thought it was a really good boot. Finally, a great touring boot with downhill performance. I picked up this year's boot and was very impressed right out of the box. You can just tell it's a beefier/stiffer boot. Then you put it on and that is confirmed. Substantially stiffer, but still tours great! And they only added a few ounces in weight. Nice work Scarpa. I've been on skis 120mm underfoot and it drives em right where you want them. The ankle strap doesn't seem to nestle in there as well as the older model? Very minor detail.

      I am very impressed in how far 4 buckle AT boots have come. It seems that past boots neither skied or walked well. The Maestrale RS does both great! Extremely free flexing in walk mode for a four buckle boot. Love the aggressive rubber on the sole. Really love the liner as its very warm, stiff in ski mode and moves freely in walk mode.

      This boot excels in a category that blends alpine touring and freeride. I toured, hiked, skied and worked in the Maestrale RS extensively last season in the rockies and chugach. Light weight, excellent range of motion, comfort and a good sole pattern/material make this boot a pleasure to hike, climb and skin with. The majority of my skiing is done in powder where this boot is able to aggressively drive skis up to 138 underfoot. No complaints. A fantastic choice for someone that skis a lot of untracked.
