A burly boot for long and heavily-loaded adventures.
The Alps cover a lot of ground, so you'll need a burly boot like the Aku Superalp GTX Men's Backpacking Boot if you plan on seeing all of it. Aku designed the Superalp specifically for big days, big loads, and extended trips, with a super-comfortable, durable, and supportive build that will help prevent injury, take the sting out of tough terrain, and reduce fatigue during week or month-long Alpine explorations. It all starts classically enough, with a soft but tough suede upper, Vibram rubber sole, and laces with boot hooks, but things get spicy pretty fast. Aku built the upper with its super-breathable Air 8000 construction to keep your feet cool, and it also gave a waterproof and breathable Gore-Tex Performance Comfort membrane that will keep you equally dry and comfortable on soggy and sunny days.
It's all built on the IMS3 chassis, which combines a cushy Custom Fit IMS 162 footbed with a double-density PU midsole for underfoot support and tosses in a medium-stiff nylon and EVA lasting board that protects your feet from rough rocks while offering enough sensitivity to make technical terrain manageable. Aku also incorporated a PU exoskeleton into the heel for extra stability and constructed the whole package with its Anatomical Fit last, which hugs your foot for a precise, non-slip fit that eliminates blisters and encourages dynamic striding so you can cover more ground with less effort, which is key when you're putting away 20-mile day after 20-mile day.

These boots came in 2 days before my 20 day trip in the andes of Peru. We hiked over 150 miles. Not a wise way to get boots before a good trip as if they didnât fit or needed a long break in period I would have been in a world of hurt.
When they arrived they seemed to fit well and the construction seemed very solid.
The first day in Peru I found that they fit well. We had a short 14 mile first day that included 2,000 feet of elevation gain, rain and mud. The boots performed flawlessly with no hot spots or fit issues.
I have relatively high volume feet that are average to wide width. I liked that the Superalp has a full lace construction so I could tailor the fit to my foot. I used the Smartwool Trekker socks.
Over the next 20 days I hiked over 150 miles with not one blister or sore foot. The boots breathe well so I never felt like I was swampy. They also are legitimately waterproof. I tested this several times when I was too lazy to find shallow routes across creeks.
The rocks in the area of the Andes we were in are primarily quartz and sharp as heck. The guides say that they need a new pair of boots every 2 treks, or 300 miles. I definitely see some where on the soles of the boots but I would say that I have over 80% life left.
Nothing but praise for these boots. My hiking partner is now buying a pair, his boots left him with many blisters on our trip.
