A new era in footwear innovation.

June 01, 2018


When it comes to all day treks in varying technical terrain, a hiking shoe’s fit and comfort determine the difference between calling it early and achieving your goal. For Spring 2019, Arc’teryx introduces the new Aerios FL Mid GTX® – a revolutionary merger of comfort, stability and lightweight protection for an allin-one single day hiking shoe.

• Comfort and weight of a trail runner combined with stability and protection for day-long hikes on technical trails.

• Optimized midcut height provides ankle support without adding unnecessary weight.


Greatly influenced by long distance trail running, the Aerios FL Mid GTX® hiking shoes are designed for comfort and agility. Trail running has many lessons to teach about technical terrain, and the designers took notes on what works best in rugged, unpredictable environments. The demanding nature of long distance hiking required a revolutionary ergonomic design to keep the wearer’s feet comfortable, protected and ready for more at all times.

“Taking inspiration from the lightweight comfort of our trail running collection, we designed the Aerios FL as a fast and light, yet protective all day hiking shoe.” Greg Grenzke Design Manger, Footwear.

Whether high in the mountain, low in the desert, or anywhere in between – no trail is too rugged for the Aerios FL Mid GTX®. Soft, flexible, molded foam wraps around the ankles for malleolus support, while an abrasion resistant TPU GORE-TEX® flat laminated membrane protects the outside from the elements. A layer of rubber is encased around the toe for extra protection and smart lug design provides a solid grip.


The designers were tasked with creating a careful balance between lightweight and comfortable. This challenge was accomplished with a flexible fabric and an elastic sole, both of which designed to maximize efficiency. The Aerios FL Mid GTX® keeps the user comfortable while moving forward in rugged terrain with a layered spring sole system that provides a soft, buoyant ride. For those seeking higher performance, it isn’t enough to just be comfortable. The designers knew this, and by encasing the upper with a single layer Cordura Mesh and a TPU Protective film, the Aerios FL Mid GTX® became a comfortable, flexible and agile solution weighing in at 335g (11.8 oz.). With all these qualities combined it ensures a lightweight and comfortable experience on any day long hike through rugged terrain.
