Scarpa Rush Boot

I used the Scapra Rush last spring for a two week expedition in Alaska's Wrangle-St. Elias Range. They worked well for both ski mountaineering and snowboard mountaineering. I was doing both and was stoked to be able to use the same boots for each activity.
They are light but still stiff for their weight (just over 6 lbs/pair). If you are looking to shave weight, and are willing to sacrifice a bit of stiffness for a lighter weight boot, then the Rush could be for you. The inventive tongue design helps to make Scarpa's line of ski mountaineering boots exceptionally stiff for their weight. It takes a little patience to figure out how to cleanly open the boot by moving the tongue to the side before getting in or out. But after two or three goes you will have it dialed and stoked on the design for the stiffness it offers.
The boots tour well with lots of cuff movement. For skiing they tighten nicely and once the forward lean lock is engaged you are ready to rip. They were plenty stiff for snowboarding. For skiing they functioned well on all but the iciest terrain. During a time or two while on skis where it was steep and icy, I would have preferred the Scarpa Maestrale's for their additional support. But would not have enjoyed the extra poundage on the way up.
Bottom line: Scarpa Rush are a great boot for ski mountaineering at higher altitude or when you are going for big vertical days and want to shave weight. If you desire the support of a stiff four buckle boot, I would go with the Scarpa Maestrale.

This is the perfect boot for doing it all. You get a light boot that can still drive a big ski, tour like a dream, and not break the bank. The dynafit tech fittings make getting into your tech binders super quick. The sole is nice and grippy on rocks when you have to scramble. And they are warm! I suffer from cold feet and these babies have done the best at keeping my feet warm of any ski boot I have had. The range of motion is so good in these boots that I ice climbed in them for 3 months while waiting for my ice boots to come in. I love how easy they are on and off, the way the tongue hinges out of the way is genius. Great for taking the liner out of the shell if you are chillin in a tent.
The only problem I had with them is the tongue of the right boot would fold where it connects to the toe box and cause the part against my shin to slip down while I toured. Fixed it right up with some shoe repair thread by stitching one side of the tongue to the main part of the liner about 2 inches up from the very bottom of the tongue. Haven't had a problem since... Great boots

I've been skiing the Scarpa Pegasus (polyurethane version of the Maestrale= cheaper and heavier) for the 11/12 season but got myself a pair of these to shave a few ounces.
The vast majority of my skiing is touring, and I'm not opposed to longer approaches to ski objectives and days with up to 10 000 feet of vertical. I don't really huck cliffs, but I do like to ski in steeper terrain. For me this boot fits the bill better than any other I have used. I still have a beat up pair of F1s that I use for speed touring and I use the Pegasus boots for my work in the ski patrol
Obviously the most important feature of a boot is fit, and Scarpa is apparently made for my foot.
The walk function is terrific and they remain comfortable for 10 hour days. I've been primarily skiing them with a pair of Movement Logic skis, which the boot drives very easily.
Worth noting: The forward lean angle is a little more upright than for the Maestrale I think.
Also the shell size that Scarpa uses for half sizes is the larger one (ie. a size 28.5 is a 29 shell with a thicker liner NOT as 28 shell with a thinner one!)

I've been skiing in the Scarpa Maestrale for the 2010/11 season and have now switched over to the Rush for 11/12 as it is basically a lighter, less expensive version of the Maestrale. I prefer three buckle boots as they have a nice clean toe profile (no 4th toe buckle) which works better for booting, climbing or cramponing. The Intution liner molds to a perfect fit and I haven't had so much as a hot spot after 20+ days of touring with the Rush's.
These are definitely a full-on touring boot and are best appreciated in the backcountry. The only reason I gave them a 4-star instead of 5-star rating is that the new arch buckle doesn't seem to clamp my heel down like the older one (Maestrale) does. On a three buckle boot this is more apparent and since I have "skinny" heels, I notice it a bit.
Still, a great all around touring boot that works well for any and all conditions.

I've been enjoying skiing the Maestrale RS mostly, but the Rush has been a good boot when I don't need quite the performance and want to shed some weight. It fits this middle ground niche really well. The range of motion in tour mode is great and everything seems really solid.

Great touring boot! They hike as well as most trail shoes, and drive most skis, including my 1st gen Zealots. I did swap the liners out for a pair of Power Wraps, but the originals seemed decent as well. A great all-arounder, lightweight, but not TOO lightweight!

What's not to love about these? Not too heavy, easy to get in and out of, they walk well, hike well, and ski well. Intuition liner is very warm and comfortable. No issues wearing these all day long.
