Safety is paramount when it comes to high mountain activities, and more so in the coldest times of the year, the Aku Hayatsuki GTX guarantees great protection for sports such as climbing or routes in technical and complicated terrain.
The Aku Hayatsuki GTX is a walking boot that is made with high quality materials and finishes and functionality to provide the best performance and a high level of comfort at all times.
Aku expands its walking boots catalog with this new high-end model as it features the latest innovations and technologies developed by the Italian brand.
The upper has protections to avoid the impact of external elements, these protections are present in the front and heel of the boot.
The Aku Hayatsuki GTX features Air 8000 technology, the first technology developed and patented by AKU since 1991 to increase the breathability of the boot.
The boot has a Gore-Tex membrane, essential to keep our feet dry in high mountain environments where we can find snow and ice for much of the year.
The Gore-Tex membrane contains approximately 1.400 billion microscopic pores per square centimeter. These pores prevent water droplets from penetrating the membrane and water vapor, i.e. sweat from our feet, from escaping easily.
The midsole features one of the brand's most outstanding technologies. The Aku Hayatsuki GTX has a dual density PU 'exoskeleton' midsole, this exoskeleton is designed to offer stability and precision in terrain of high technical difficulty and with large vertical slopes.
It is a die-cut carbon fiber and EVA board that adds extra stiffness, always necessary for a walking boot of these characteristics, plus, to complete the midsole, a custom fit aluminum insole is also incorporated.
The outsole of the boot features Vibram Curcuma technology, it is a 'Megagrip' compound that provides great grip on both dry and wet terrain, even with snow and ice without penalizing the durability of the boot.
This is a high quality walking boot made with exclusive materials to be used by a profile of athletes who need a high performance boot for routes and activities in high mountain environments with complicated and steep terrain.
The boot has a high weight, both in the men's and women's version, and there are many technologies that are implemented, specifically the Aku Hayatsuki GTX weighs 900 grams in the men's version and 770 grams in the women's version.
Note that the boot is available in a version for women that has a last designed especially for the female foot, which increases comfort and fit in this model.
In short, this is one of the most advanced walking boots on the market today, indispensable for our routes or activities in high mountain environments and mountainous terrain of high technical difficulty.
