La Sportiva Trango Tech GTX Mountaineering Boot - Men's


Why We Like The Trango Tech GTX Mountaineering Boot

The La Sportiva Trango Tech GTX Mountaineering Boot bridges the gap between both backpacking and mountaineering for an option that helps us confidently tackle all types of terrain. We appreciate how its low-profile sole and midsole allow technical footwork and edging capability when climbing easier graded routes, while also offering semi-automatic crampon compatibility for glacier travel. The waterproof upper and GORE-TEX membrane keep your feet dry across mountainous terrain, and the gusset-free tongue construction increases comfort for long miles on the trail.

  • Boot that's equally suited for both backpacking and mountaineering
  • GORE-TEX membrane blocks moisture and allows vapor to escape
  • Gusset free tongue adds comfort during long miles
  • 3D Flex system offers precise support across rough terrain types
  • Low profile midsole and outsole enable technical foot work
  • Vibram CUBE soles offer edging capability and enhanced traction
  • Impact Brake System makes strenuous descents more comfortable
  • To-the-toe lacing system offers a precise fit for enhanced control
  • Item #LSP00JI

Bad fit

I've used it several times
Runs small
Size Bought
5` 11"

The good: Well made, stiff, and super grippy. The bad: The fit is bizarre. I’ve tried to break these guys in for a long time to no avail. I’ve owned them for a year and they still give me extremely bad blisters in the heels. This would indicate they are sized too big, but that said, they feel extremely tight on the top of the toe box making them feel too small even though I have room in front of my toes. Theoretically, they are exactly my size. Long story short, I can’t tell if they are too big or too small. I’ve never had this issue with other Sportiva products. I thought they’d break in better but they haven’t. It’s too late for me to return them, otherwise I would. I may try to sell them elsewhere but I would seriously recommend getting a few sizes to really nail it.

Rigid + Cushioned + Light = Bravo!

I'm a hiking guide in southern Utah canyon country. I wear a Euro size 45 in most boots (La Sportiva, Salewa, Asolo), and a Euro size 45.5 in Scarpas. I require boots that are notably rigid from heel to toe, because they prevent my feet from the constant bending that triggers plantar fasciitis. Yet I also need boots that have sufficient cushioning to allow me to hike long slickrock routes daily. I much prefer all-synthetic boots to leather or partially-leather boots. And, of course, I want my boots to be as light weight as possible. Previously, I relied on La Sportiva's Trango TRK. I was very happy with them, but they've been discontinued, so I switched to the Trango Tech. Opinion: It's excellent, and will be "my" boot as long as La Sportiva keeps it in production. The Techs are just as stiff as the TRKs, perhaps a bit more so. If anything, they might be slightly more cush. And they're exactly 1 ounce lighter (per pair, without insoles) than the TRKs. My size 45 Trango Techs weigh 2 lbs 13 oz, according to my scale. Sizing for the Trango Tech seems to be nearly identical to the Trango TRK. Perhaps the Techs are a smidge shorter (due to the angled toe box), but size 45 still works for me. Conclusion: If you're looking for that rare combination of lightweight + rigid + adequate cushioning, in an all-synthetic boot, for technical dayhiking, the La Sportiva Trango Tech might be your boot.

So far so good

I've used it once or twice and have initial impressions
True to size

Bought these for anything where the Nepal Evo (or similar mountaineering boot) is not necessary. Aside from about 20 minutes on a class 1 hiking trail, wore these for the first time on Capitol Peak in Colorado (17 miles, 5,000+ feet vert and lots of heads up class 4). They are comfortable, and right out of the box performed extremely well everywhere from the fast paced approach to technical edging where it really counts. The break in period is minimal, however even though I didn't have to use moleskin/tape, I recommend at least having some with you if you're doing a long outing the first time using these.. Based on first impressions I strongly recommend this boot. Regarding sizing, my climbing shoe size is 41.5, and bought these in a 42. I was wearing a moderately thick wool sock and the fit is pretty good. It's on the roomier side, however a 41.5 with this thick a sock would be too tight. If you are not planning on wearing a thicker sock and will not be using them in cold temps, you will probably be ok sticking with your true climbing shoe size.
