First pair of AKU

This is my first pair of AKU. I have to say that I am going to be buying more of these boots.

Great boots

I was looking for a basic hiking boot with enough support and space to accomodate my feet (EE). After using the boots for about two weeks, I’m extremely satisfay with this AKU boots. The are light and have support at the same time, allowing me to easily walk on trails and snow (up tp 2 hours no complaints) and they are indeed water proof. I particularly like the rubberized edge that protects from water/salt/etc the upper suede leather are.
Will consider buying them again in the future. I would like to see some of the backpaking boots with the rubberized band as well.

The Real Deal

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.

Thanks Aku!
