Sizing notes

For rock climbing shoes: Choose soft shoes two to three sizes smaller than your street shoe size. We recommend you fit your trad shoes one to two sizes under your street shoe size. Remember to factor in stretch. Unlined slip-lasted shoes tend to stretch about one full size. Lined shoes stretch about a half size. Remember: a well-fit comfortable shoe will work better than an ill-fitting tighter shoe. For boots: Add one half size to your street shoe size. You should be able to slip one finger behind your heel when you are standing up with the boot unlaced and your toes touching the front. If the boot is too short, your toes will get smashed walking downhill. Too long and your heel will slide up and down and give you blisters.

Rated 3 out of 5 by from Lighter but less durable than Trango S Evo I had worn out my Trango S Evos and wanted a replacement, but for whatever reason REI does not carry these anymore, so I decided to try the Trango Cube GTX. Width is very similar to the Trango S Evo, but volume seems a bit tighter. I find that the toenails on my big toes are hitting the top of the toebox. Grip and edging on rock is great. Have not tried them in snow yet. Durability is a concern. I've only used these for two days and the front "climbing zone" area is already showing significant wear.

Rated 3 out of 5 by from Light and dries fast, toe area sole wears quickly I used these for a number of trips in coastal Alaska this past summer. Break in was minimal and the forefoot width is adequate for medium to wide feet. The support is great and the boots are extremely light and comfortable, and breath well. They dry faster than any other light mountaineering boots I have owned. I was skeptical about the plastic lace eyelets, but they held up well to brush and rocks. I like that La Sportiva didn't use the terrible Vibram Mulaz sole on these, and the traction is actually quite good on most vegetated and rocky terrain. However, the 'climbing zone' rubber up front is butter soft and extremely thin. I wore through the toe rubber of the boots after fewer than 10 days of granite and slate backpacking in the alpine. The rest of the boot was still in good shape, but the sole was gone and I could see the stitching of the upper showing between the rand and the sole. I understand the use of sticky rubber in the toe area, but it limits the life of the boot to one or two hard trips on abrasive rock. Not acceptable.

Rated 1 out of 5 by from Sole wears quickly in the toe area I purchased these in Spring 2015. I live in northern SE Alaska where I primarily hike through rainforest, gravel bottom river valleys, alpine vegetation, snow and glacier ice(crampons) and granite. Out the gate I was 100% happy with this boot design. They fit my feet perfectly. No break in time was necessary, excellent water repellent uppers, no stitching to come apart or wick water into the interior, excellent lacing system. The weight of these boots felt closer to running shoes than a hiking boot. They handle my step in crampons perfectly. I had no complaints on the initial hikes. Just two short backpack trips into these boots I noticed the toe area of both soles wearing quickly with vertical splits developing on the rubber rands of both boots along both toe areas. Alpine hiking season is brief here so I continued to hike in these boots through the remainder of summer 2015. I only did five backpack trips of six days or shorter and a few day hikes but by Fall the toe areas of both boots soles were severely worn with vertical splits in the rubber rands. Move ahead to the summer of 2016. I decided to continue to use these boots since the warranty for defective material didn’t seem to apply to the toe areas of these boots. I used them only three more times (12 days), before the soles of both toe areas were completely worn away. A real shame, as the uppers are in great shape and I genuinely like this boot. I think it’s an outstanding design except for the toe areas of the soles. Do yourself a favor and ignore any product that describes a hiking boot sole with anything other than a tried and proven Vibram sole from toe to heal. This product is unacceptable until the sole design is replaced by something more wear resistant.

Rated 4 out of 5 by from Great general mountaineering boot Bought these boots at the beginning of the winter season. I was looking for a low profile mountaineering boot, that climbed well. Almost everyone I've ever climbed with has a pair of these boots in their gear closet, so I decided to pick up a pair. To start, they fit really well. The slim profile feels great. However, I found that I definitely wanted to wear gaiters with this boot. They are also pretty lightweight which make them great to wear for the approach. These boots climb really, really well. Their low profile and the slight flex allows you to feel the rock and maneuver through various technical sections with ease. If you're looking for an all purpose mountaineering boot that climbs well, then this is the boot for you. I would not, however, use it for ice climbing.

Rated 5 out of 5 by from Great boots Have had these for a couple of years now and mainly done stuff in NH, last hiked in them doing tripyramid 12 miles, these boots are solid, have great ankle support and are comfortable to walk in. once you get past the 'lets use all the colour we can' look of the boot, makes them easy to find in a crowd <g> you will not be disappointed.

Rated 5 out of 5 by from Great fit I knew that La Sportiva brand was a good fit for me but these boots were even better than expected. after 2-3 days of hiking they felt like old favorites. the narrow welt and vibram sole provides secure footing scrambling over rocks and boulders and if necessary I could probably use these for moderate rock climbing. Great boots and the colors are a nice extra

What's this boot designed it a mountain/backpacking boot for carrying heavy packs.....or is it meant to be like a double boot for high altitude glacier climbing ? I see it says it's not insulated,so I'm thinking warmer mountain climbing/hiking

Asked by: Spason
The Trango Cube is more of a general mountaineering boot. It could be used for long backpacking trips where you are carrying a heavy load and encountering steeper terrain. This might not be the most comfortable option in warmer weather. As you have noticed, there is no insulation in the boots so using these for high altitude mountaineering (something like Mt. Everest) would not be recommended.

How do these fit compared to La Sportiva Trango TRK GTX? I have Trango TRK in 45.5 and they fit me perfect. I'm looking for something a little stiffer than the TRK for carrying heavier loads and they Cube seems like the answer. Thanks!

Asked by: nickstone
The Trango Cube GTX Mountaineering Boots have a very similar fit compared to the Trango TRK as both are using the same Trango last from La Sportiva.
