Russ M.wrote a review of La Sportiva Trango Cube GTX Mountaineering Boot - Men's on June 15, 2015
Familiarity: I've put it through the wringer
Fit: True to size
The fit of these boots is flat out remarkable. I 'm a 12 in running shoes and a 45/46 in climbing shoes; I bought a half bigger to wear 2 pair of thick wool socks. No blisters at all, not even a hot spot. My foot is average across the ball and a bit narrow in the heel. I walked them in the foothills for five or six days being aware of normal foot problems with new boots... there were None... I've been climbing for over 50 years and have had access to the best climbing gear out there; La Sportiva has out done them self's with this boot. Up hill with weight (50/55 lbs) my feet were happy, kicking secure steps in Sierra cement for clients easy, post holing ( with gaitors ) a grunt, yet compacting and producing an edge under the surface to stand up on was easier with the sharp edge of these wonders... Plunge stepping down ,I felt under full control as I did long ago in Super Guides or Makalu Doubles. They are so light, it's almost like I'm wearing a trail running shoe, so connected and with persuasion edging. On to rock, 5.6/5.7 is fun on the tips... I'm old school, so, edging comes naturally to me as with Kronhofers or Spiders; not super stiff though, the rocker across the ball of the foot is on a slight diagonal which presents a very natural feeling foot fall .
I can't say enough about these boots, totally water proof, the lacing is simple and quick; there is a lock on the lace at the ankle that allows for exacting tension. It does require a bit of break in above the ankles, so start off lacing lower at first... I've put at least 65 to 75 miles on them and gone from 9000 to 13500 four or five times in the last month; my feet are the happiest they ever been.
Blizzards in May and post holing in June, a crazy start to the Sierra season; I'm enjoying our mountains to the fullest because of these boot! Really, I'm not kiddin".
