Review: La Sportiva Trango Cube GTX

La Sportiva’s Trango lineup has undergone a progressive renewal over the past few years and at the time of this post includes the Trango Cube GTXIce Cube GTX (light ice climbing boot), Trek (hiking boot) and the new Tower GTX (basically an updated Evo).  This lineup of boots is really focused on lightweight performance.  Now the Trango Cube GTX fits squarely in the middle between the winter focused Ice Cube and the summer specific Tower and has struck a Goldilocks zone.  Warm enough for long and wet snow routes but still dexterous and secure on rock, an incredibly versatile alpine boot.

For such a versatile and stiff mountaineering boot the Trango Cube is amazing light.  The pair that I have weigh in at 766g per boot, significantly lighter than the old Trango S Evo’s and almost the same as the new Trango Tower boots.

The soft rubber on the soles of the Trango Cube boots provides amazing traction but wears quickly. This pair has seen about 20 days of snow and rock climbing.

The fabric combination used on the Trango Cubes strikes a great balance between lightweight comfort and warmth.  The boots are not too hot for alpine rock but still warm enough for slushy snow slogs.  They do have limitations though and will eventually get saturated with water if pushed.  On a recent alpine trip I ended post holing though isothermal snow for about 10 hours, the Cubes became saturated after about 6-7 hours.

The fabric along the side of the Trango Cube’s is stiff and durable with clear, flexible lacing harness.

The Vibram™ One rubber soles feature a climbing zone at the toe, a braking zone at the heel and are made from an incredibly soft rubber.  The up-side to the soft rubber is the amazing traction or grip that it provides on rock.  Combine this with the stiff sole and these boots to excel at climbing.  The downside is that the soles wear out fairly quickly, especially at the toe, when used for climbing.  My current pair have around 20 days of use so far on a variety of snow and rock routes in the Canadian Rockies and I’m getting starting to wear the rand at the toes.

Versatile, stiff and lightweight, La Sportiva’s Trango Cube GTX are my go-to boots for summer alpine routes.

Pros:  Very lightweight, stiff, fairly waterproof, comfortable

Cons:  The soft Vibram One soles wear very quickly and the rand is easily cut on sharp rocks

Overall:  A fantastic summer alpine climbing and mountaineering boot.  If you want one summer boot that does it all then this might just be the ticket.  Be prepared to get them resoled or replace them every 20-40 days though.

The boots for this review were purchased by me and I wasn’t influenced in any way, it’s just one mans opinion.
