No more mention is needed.

Reviewed by Cascade Hiker from washingtonia on Wednesday, October 15, 2014I wanted to like these boots but on my first trip wearing them I ended up with a blister on the *top* of my left foot... highly unusual and a first for me (I've been hiking for 30 years). Upon inspection it turns out that the interior fabric lining is loose and had doubled up causing an area of increased friction, and thus a blister. Otherwise they seemed to perform OK.
Not much to be done about loose fabric inside the boot, so I had to return them.
Total cost of buying defective boots: $12.47, repackaging and a lot of browsing time...
Reviewed by Fire Danger from Oregon on Friday, August 1, 2014My old boots just finally gave up and I have never liked my Nikes so I bought these on a whim. after a very short break in they were my foot wear for 6 days and 35+ miles in Glacier Peak Wilderness. It is a big boot but it did not over heat my feet even in the summer heat. They did great on snow, mud, creeks and were really good when going down the many 45 degree slopes.
I may have to buy a second pair before they go away because I like them that much.
Reviewed by Rocky from Boulder, CO on Saturday, June 28, 2014AKU has a reputation for innovation, and these boots reflect this. They are very light, 3 lbs 2 oz in my size 11.5 (Euro 46). This compares favorably to the popular Asolo TPS 520 backpacking boot at 4 lbs 4 oz in the same size. The AKU are more than a half pound lighter on each foot. The sole is very stiff for such a light boot, comparable to a heavy-weight backpacking boot, but the sole is also extremely thin. It measures just a quarter inch at the base of the lugs to the insole; a little over a half inch from the ground to the ball of your foot . This is about half the depth of the sole of the Asolo boot at the same place. The sole of the AKU Tribute (also at STP) is over an inch thick at that point.
The sole of the AKU boot has an "alpine cut," that is, the sole is trimmed inside the perimeter of the upper. This improves traction on narrow footholds, but also offer less protection to the upper from protruding rocks and boulders. There is no rand, just leather patches around the toe and heel with the area inside the instep unprotected. A single trip on some rugged Rocky Mountain terrain could shred this boot.
Despite the fragile character of the boots they have worked well on a couple of trips where crampons (10-point on one trip, 6-point on another) have been helpful in climbing long patches of modest snow slopes. My feet actually got chilled on these trips, something I've never experienced with more robust boots. They also worked well on stiff approach trails. On another trip over an old pack trail to a former fire lookout it became awkward to hike the easy grade, the boots were just too stiff.
The boots seem sized for a mid-width, mid-volume foot. My low volume narrow (AB width) foot fits comfortably with a mid-weight cushion sock and standard liner with wiggle room for my toes and a little extra width across the ball of my foot. I've added a fairly thick insole which also reduces the volume to better fit my foot. About six miles into my first trip the boot began biting into my heel. I attribute that to the stiffness of the boot not being a good match to the near flat tundra slope I was crossing. The toe and heel counters give the upper much of its impressive support, but have little padding, little give. Otherwise, the boots have been very comfortable.
The boot works very well on rugged terrain, but not too rugged since the upper is not well protected and the sole is very thin. It is not for easy trails or harsh terrain, but good on snow. They remind of some Italian trail boots I had long ago, boots that I did shred after just a couple of trips. The quality is excellent. This is a five-star boot if it matches your specific needs, but I give it three stars because in my opinion it is too specialized and fragile for more general use. Then again, I only do mountains.
