Ecco Exostrike Hydromax notable features

-This boot features a robust construction necessary for hiking at the speed of a running shoe. Chief among its features is the water-resistant Hydromax-treated leather upper that protects the boot from wear-and-tear caused by external moisture.

-Another key component of the Exostrike Hydromax is the ultra-light Phorene midsole characterized by a high energy rebound.

Size and fit

Designed for both men and women, the Exostrike Hydromax is a high-cut boot with an upper made from leather. Thus, it easily conforms to the shape of the foot after some time. The traditional lace-up closure lets the wearer adjust the fit whenever needed. Plus, the PROSOMA T.PU heel cup ensures a snug fit with each step.


Designed for rugged terrain, the Exostrike Hydromax boot comes with a high-quality rubber outsole that offers superior grip and durability for all weather conditions. The lugs are semi-aggressive. They are deep enough to create good traction when traversing wet or slippery surfaces. There is also enough space to shed mud and debris easily.

Even more interesting than the Ecco propriety outsole is the T.PU heel piece. It’s strange-looking but it has a very important purpose. And that is to provide support and protection. While the rest of the shoe is pliant and soft, the heel cup is totally rigid.


This boot features Ecco’s proprietary midsole which is made of P.U. Phorene. According to the company, it’s an ultra-light material that offers unparalleled softness along with improved shock absorption qualities. 

The midsole is produced through the direct injection process, which they call “Fluidform”. Direct injection isn’t a new process, but Ecco’s approach to it is different and much more revolutionary. Through the Fluidform, lightweight fluid materials are transformed into soft and durable solid soles. They use a 3D anatomical last to ensure that the midsole and the upper greatly conforms to the shape of the foot.


The Exostrike Hydromax features a durable upper made of yak leather. The yak is a  long-haired domesticated bovid that lives in the alpine rangeland of the Tibetan Plateau, where few other animals survive. Yak creates an extremely durable leather due to its thin, compact woven collagen fiber and fine grain. 

Furthermore, the yak leather upper is treated with Hydromax - another propriety technology from Ecco meant to enhance its water resistance, longevity, and softness. 

This boot has a unique collar design that is more for aesthetic purposes than functionality.
