Product Description Item No.   10243530

The La Sportiva Nepal Cube GTX Boot is a lightweight mountaineering boot for conquering the next mixed climbing route on your list. At 31.5 ounces you won't exactly be a quick little mountain goat, but you'll certainly have dry, warm feet due to the GORE-TEX® Insulated Comfort lining. The 3.2mm silicone impregnated Idro-Perwanger Roughout leather upper is incredibly tough and won't take any crap from wayward pieces of rock or ice along the way. A Vibram® outsole you can trust to grip the terrain and a midsole that allows for crampon attachment when you need extra bite in your step.

FEATURES of the La Sportiva Nepal Cube GTX Boot

  • Exceptionally lightweight thanks to an innovative and lighter sole/midsole package which uses a highly insulating Carbon Tech honeycomb footbed
  • Gore-Tex Insulated Comfort membrane provides waterproof breathability
  • Innovative 3D Flex ankle and removable adjustable variable fit tongue
  • Ideal for winter mountaineering, ice climbing, mixed climbing
  • Technical, warm, lightweight mountaineering boot

Vibram rubber compounds and technologies are the gold standard in the outdoor industry for reliable, high-performance grip and traction. They offer precise, unparalleled responsiveness and support that's specifically engineered for your activities. "With the right foundation, you can build anything." -some guy.


If you haven't heard of GORE-TEX by now, you've probably been living under a rock. And that would make sense, because living under a rock is probably the only place where you wouldn't need the durable waterproof and windproof protection that GORE-TEX fabrics offer. So when you're ready to venture out from under your rock, arm yourself with the comfortable protection of GORE-TEX.

La Sportiva footwear is built and offered on European half sizes, which are smaller increments than US half sizes. This gives them four extra sizes per size run, and ultimately gives you a better fit.

Please review La Sportiva's size conversion chart above to help determine your ideal size. Below you will find additional information about how to fit and break in the different styles of La Sportiva footwear, which will also help guide you to the correct size.

• As a general rule soft shoes like climbing shoes require a tighter fit, or about two to three sizes smaller than your street shoe size.
• La Sportiva recommends you fit your trad climbing shoes one to two sizes under your street shoe size.
• La Sportiva offers a lot of lasts, and each offers a different fit and feel. Remember to factor in potential stretching.
• Unlined slip-lasted shoes tend to stretch a bit more than lined shoes, or about one full size.
• Lined shoes stretch about a half size.

• PERFORMANCE FIT - offers a high performance fit and a downturned last.
• TECH FIT - a more technical fit and a last with neutral profile.
• COMFORT FIT - a comfortable fit and a last with more volume and a neutral profile.

• Find your US Size in the guide above, then find the Euro Size conversion and add one half size.
• The ideal size holds your toes ever so slightly away from the front of the boot while the lacing system is snug across the top of your arch.
• If you can try to boots on beforehand, make sure you wear the same size and weight socks you would typically wear with the boots, and any orthotics or custom footbeds you use.
• It is ideal to fit boots later in the day since feet are prone to swell slightly as a day progresses.
• Wear your boots indoors only until you are confident about the fit.
• Your foot should feel snug (not tight) from the arch back into the heel pocket with just a minimum lift as you walk. If your heel lifts make sure the lacing is snug and not too loose.
• Your toes should NOT touch the front of the boot, but when you kick the toe into the floor, you should know where the front of the boot is. You want just enough room to wiggle your toes.
• If your toes or sides of your feet feel squished, most likely the width is too narrow and the boot will not work for you.
• If your toes touch the front of the boot, most likely it is too short and you need the next half size up.
• Make sure to keep all original packaging that came with your boots until you are sure that you are happy with your purchase.

Rated 5 out of 5 by from Super Light, Stiff w/ just a bit of Flex, great fix to the original EVO LaSportiva has had a gap in their product line for years which I think they have filled beautifully with the Nepal Cube. Their entry into a serious hiking boot starts with the Pamirs but they are too light, to much flex, no insulation, but great to hike in all day. The KORAKORUMS are medium stiffness, crampon compatible, medium insulation, good to hike all day, but you will get wet in heavy snow. Then the EVO, which is Super Stiff, Heavy Insulation, never get wet in heavy snow, indestructible, but near painful for full day hiking (to heavy and stiff) more of a technical only boot. There is nothing in between the Korakorum and the EVO until the NEPAL CUBE. It has a 2 week break-in, medium stiff flex, suffer a bit on all day hiking but do-able, breathable heavy insulation, built like a tank, never get wet. The weight, medium stiff flex and breathability lets you do both hiking and technical with them. I was switching between Korakorums & Baruntse, but now I just use the Cubes only!

Rated 4 out of 5 by from First time use Recently I used them at Pico de Orizaba and they worked perfectly, I had no trouble with the crampons and the insulation kept my feet at a decent temperature. Great Design!

I purchased a pair of these in size 48 in February 15', but had to return them cause college is expensive. But now that I actually have the expendable cash, you guys no longer carry them in 48. Can't find them anywhere, whats the deal?

Asked by: SZilla
Hey there, Thanks for reaching out to us. Unfortunately, we do not have that size in stock, but keep in mind, we're getting new inventory every day! I'd suggest checking the site periodically and hopefully we'll have those in soon. Hope this helped you out.

Would the Petal Lynx crampons be compatible with these boots?

Asked by: Gadjo
Hey there, Thanks for reaching out to us. This is one of the best questions we've ever received...and I'm proud to say that I've found the answer! The Petzl (not 'Petal', I assume that was an auto correct) Lynx will fit on any boot with a rear welt...and these boots do have a rear welt! So, yes, Petzl Lynx crampons are compatible for this boot. Hope this helped out!
