Gear Review: AKU Hayatsuki GTX Mountaineering Boots

AKU Hayatsuki Mountaineering Boots Review

I’ve had a few months to demo and review the Italian made AKU Hayatsuki Mountaineering Boots and I’m ready to share my opinion on them! Let’s get the disclaimer out of the way first. I first heard of this company through a social media ad and I purchased a pair of the AKU Rock DFS Approach Shoes because I have a thing for approach shoes! The shoes performed so well I published this review and later reached out to see if I could get a media sample of the AKU Hayatsuki Mountaineering Boots to review. AKU supplied me with a pair to check out but this has in no way effected my opinion of the boots. Read on to see how they were tested and how they performed!

How they were tested:

Test period: December – March

Use: Winter hiking, mountaineering, and waterfall ice climbing in the White Mountains of New Hampshire. Approx. 20 days of use, 100+ miles, over 40,000 feet of elevation gain/loss.

Bottom Line (TL;DR version)

These are a solid choice for the winter hiker/climber who spends equal time between general winter mountaineering (snow climbing) and more technical waterfall ice climbing that won’t break the bank!

The Details:

Sizing/Fit/Comfort:

I went with a UK 8, EUR 42, USA M 8.5 and the fit was perfect for my medium width foot with a regular arch and a slight Morton’s toe. The lacing system has a great pulley system at the lower top of the foot, 6 “mini” pulley’s to be exact then a self-locking ratchet mechanism. This system makes securing the foot in the boot super quick and efficient. The result is zero toe-bashing while kicking up waterfall ice while wearing crampons or while descending of any steep hiking trail. I never felt a need to “snug up” my laces for the descent with these boots feeling comfortable and secure all day long!

Performance:

For general winter hiking and mountaineering these performed quite well! AKU doesn’t list how much Primaloft insulation is in the liner but there is enough to keep my feet toasty down to 10 degrees below Fahrenheit with wind chills around -20 to -30 above tree-line. My feet stayed warm throughout each trip (wearing my Darn Tough Mountaineering Socks)! For general winter hiking and mountaineering I paired them with my Petzl Vasak 12-Point Mountaineering Crampons and they worked great together!

For ice climbing I was quite impressed with their performance, especially at the price point! The lasting board, which gives the sole its stiffness, is made out of “6-4 MM Nylon & Die Cut EVA for Rock Protection & Stability”. More important to me is the welt is fully compatible with my technical ice climbing crampons with a solid front and back lip on the welt. My Petzl Dart Crampons fit perfectly on the welt and felt secure on many pitches of Grade 3 waterfall ice.

Summary

The AKU Hayatsuki Mountaineering Boots are a great winter “all-a-rounder” that will basically perform well in pretty much any snowy situation below 8000 feet. This makes them an excellent choice for winter hikers working on their “Winter 48” 4000 footer list, and for winter hikers who are considering breaking into the waterfall ice climbing sport. They are technical enough to handle waterfall ice and mixed climbing at almost half the price of most technical ice climbing specific boots. The fact that they are made in Italy is apparent in their craftsmanship and I have no doubt these boots can survive a decade of winter exploration. If you’re in the market for a great pair of winter hiking boots you should give these a try!
