Seriously high-quality hiking boots

This is my second pair of AKU hiking boots. I originally had the Tengu Lite series, but they were stolen, leading me to get a new pair of Alterra's.

For a comparison, the Tengu's fit quite narrow in the toe box, whereas the Alterra fits much better width wise. Perhaps due to the dimensions across models, for the Tengu's, I would have recommended one size UP from your shoe size, whereas for the Alterra, I went with one size DOWN, and they fit perfect - something to be aware of across models.

Specific to the Alterra, the sole makes good solid contact with the ground and I have found the compound to be excellent in wet conditions (no slipping on rocks). The tongue is great in that the fabric comes right to the top of the boot preventing any water from getting in. Looking at AKU in general, their quality of materials and construction are simply excellent.

Yes, these boots are a treasure

At 74 years young, I visited my daughter in Colorado and while there, I hiked Quandary Peak to the summit of 14,000+ feet wearing these wonderful boots. My own feet never experienced any soreness or hot spots. In fact, the boots were never an issue, which is a tribute to how well they are made. I carried a pack with gear and extra water. The boots easily passed this test!

Best boots I've ever had

I love these boots. Comfortable, rigid, lightweight and grip like crazy. I tried these AKU boots because the quality from other makers now days seems like it has gone downhill, and I'm glad I did. I'm being hard on these boots and they're show no signs of distress. The craftsmanship is top notch. Thanks
