The AKU Tengu GTX is a refreshing piece of mountaineering footwear in that it’s both lightweight and high performance. Not always a combination that’s easy to get right, we’re happy to report that the Italian brand AKU have absolutely nailed it with this one. A technical, semi crampon-compatible boot; outdoor enthusiasts will love what this product brings to the table.
First order of business, shining a spotlight on the new Vibram Curcuma outsole. Combined with the exclusive AKU Exoskeleton midsole, the Curcuma provides the wearer with superb stability which in turn significantly improves precision during treks and climbs. If you’ve ever tried to climb a mountain in wellington boots, we haven’t but we imagine it’s extremely awkward, you’ll be glad to know that the closely-fitted wrap-around design of the Tengu GTX is a million miles away from that.
"...a good waterproof defense system that will keep your feet dry and warm when you’re above the treeline."
The Internal Midsole System (IMS 3) guarantees a consistent distribution of pressure, provides shock absorption, and minimises frontal and lateral slipping under heavy use. We’ve already touched on the Exoskeleton but we feel like it’s really worth emphasising just how effective this clever piece of boot architecture is at looking after your feet without weighing them down as a trade-off.
One thing that’s absolutely essential in a mountaineering boot, especially in one you’re planning to use for winter adventures, is a good waterproof defence system that will keep your feet dry and warm when you’re above the treeline. The Gore-Tex Performance Comfort system in the Tengu GTX delivers precisely that, leaving you to enjoy the mountain scenery rather than stew in the misery of having numb feet.
AKU have a very decent track record when it comes to producing stylish outdoor-focused footwear, and the Tengu GTX definitely continues in that tradition. Whether you get these in black and orange or turquoise and orange, we think the general shape and aesthetic of them really stands out; especially when you remember that most mountaineering boots aren’t exactly renowned for their artistic endeavour.
