HOW TO CHOOSE YOUR SIZE
We create our footwear using lasts based on real feet. Because of this we make it easy to find your perfect fit.
1st. Step onto a piece of paper and mark just behind your heel and in front of your longest toe.
2nd. Do this for both feet and then measure the centimeters between these lines. This measurement is your Mondopoint.
3rd. Using the measurement from your longest foot find your correlating size below.
I knew from the moment I opened the box I was in for something special. Starting from the bottom - the new Vibram sole has excellent traction and is way lighter than it looks. The midsole is very supportive and stiff in all the right ways (kicking steps up steep snow - no problem!). The insole is not spongy or flappy like other big name brands. The uppers wrap your feet in glorious and beefy Air8000 - which looks super bomber. Even unlaced - I get double the support of other brands. The integrated sock is lush right out of the box and looks to keep feet dry in over 6" of standing water.
So -how do they fit and how do they perform? Short answer is: use the Aku Size Guide and expect some wiggle room for toes. I'd say these feel about a 1/2 size bigger than similar sized Sportiva boots like TX4. The Tengus are narrower than the TX4 at the toes - perhaps my only improvement suggestion is to allow more pinky-toe splay (maybe an extra 4-5mm). See the picture to compare (note the TX4s have an extra pronounced bit of sole to prevent supination -which is a great feature to prevent rolling ankles). I think if you are aiming for a performance fit with thin socks I'd go a half size down from the Aku size chart - but feet will swell on warmer hikes so take this with a grain of salt.
Performance wise - I did what anybody would do and took these for a stroll 1300 vertM up a mountain to a high-altitude climbing crag. Mix of ice, snow, scree, slab. The Tengu Lites bashed their way from A-Z and back again. My feet were warm in -10C with wool socks and I did not notice any weight differences with other approach boots like TX4. I'm using the TX4 Mid as comparison as the Tengus do not feel like traditional hiking boots to me. They feel like incredibly burly hightop approach shoes - which is exactly what you want when getting off the beaten path and dealing with a variety of surfaces.
To sum it up -though these boots are a bit on the pricey side - what you get for your hard-earned bucks is a fantastic boot that will last twice as long as your typical Salomon units with a minuscule weight penalty. I think the closest competitor to this boot would be the Salewa Mountain Trainer Mid GTX - which is also fairly decent but more clunky and heavy-feeling.
I had never heard of Aku prior to my purchase, having worn Scarpa and Sportiva forever. After a long bout of OCD researching I came across this brand and decided to give them a shot. Not. Looking. Back. And psyched to pickup their new approach line once it's available in Canada.
Great fit and feel for a lightweight mountain boot. Great edging on rock and sole stiffness works well front pointing on my crampons. Stiff sole was also great in my aiders, (etriers), while working on multi-pitch rock routes in winter. Integral sock/tongue is nice to keep debris out, love them.
