Aku Tengu Lite GTX notable features

-Designed for various types of terrain, the Aku Tengu Lite GTX is made with lightweight and durable materials.

-This trekking shoe integrates several interesting technologies for better performance. These include the Aku Density midsole, a Gore-tex waterproof membrane, and the Vibram outsole. Furthermore, the Aku air system ensures that the shoe is breathable by incorporating a special fabric that is 11 times more breathable than other linings.

Size and fit

The Tengu Lite GTX has a suede upper which adjusts to the shape of the foot. This hiking boot from Aku also features a wrap-around and anatomical fit to promote dynamic action when walking on rough terrain. Meanwhile, the Gore-Tex® elastic sock ensures a precise fit, along with the lacing system that extends towards the toes.

Outsole

The Aku Tengu Lite GTX is made with Vibram® Curcuma outsole that has shock-absorbing qualities, particularly in the heel area. It is resistant to abrasion and has a good level of cleating. The unique design of this Vibram outsole allows for foot flexibility and protection. Furthermore, its lugs are widely spaced to minimize clogging of dirt, mud, and debris.

Midsole

The Tengu boots from Aku are made with a double-density midsole which is fabricated by injecting the EVA material of a first density and EVA material pellets of the second-density into the mold. During the process, the size, shape, and location of the density sections are accurately controlled and defined. Shoes with dual-density midsoles tend to be more durable, lightweight, comfortable, and climate-controlling. They are also anti-static, which means they have low electrical resistance.

The midsole is composed of an outer skeleton in light PU (polyurethane) which goes up at the rear, protecting the heel for better support and flexibility while walking. This exoskeleton technology, which is exclusive to Aku hiking shoes, creates an asymmetrical structure with a wider inner part and more PU in the center for pronation control.

Upper

The AKU Tengu Lite has a unisex design consisting of suede and AIR8000® fabric. Suede is a pliable and durable leather which makes it a good material for hiking boots. AIR8000® is an exclusive AKU technology designed to give the boot lasting breathability. This special type of fabric is up to 11 times more breathable than other types of lining materials.

This waterproof hiking boot also uses a GORE-tex membrane for maximum water and moisture protection. A stiff material that wraps around the ankle cuff from the heel is added to provide additional support. The interior of the heel is reinforced with a very tough thread to prevent wearing.
