Size and fit

The Arc’teryx Aerios FL GTX is a relatively true-to-size hiking shoe for men and women. Its fit is crafted for outdoor enthusiasts with standard-width feet. The shoe’s traditional closure system allows wearers to achieve a secure and personalized lockdown.


This low-top hiking shoe from Arc’teryx employs a Vibram outsole to increase ground adherence. It uses a mixture of angled square and rectangular-shaped lugs to render traction on challenging terrain. Several grooves are found at the outsole’s rear area for added control in downhill conditions. This component is also made of a durable Megagrip rubber compound which makes it resistant to wear and abrasion.


The Arc’teryx Aerios FL GTX features a compressed EVA midsole to supply adventurers with cushioning over rugged terrain. It also promotes responsiveness and shock reduction. A shank made of thermoplastic polyurethane (TPU) is embedded into the midsole to imbue the shoe with rigidity. 

A removable 4mm Ortholite molded footbed is integrated into the Arc’teryx Aerios FL GTX to give underfoot comfort and arch support. Its design also wicks excess moisture and promotes breathability.


Arc’teryx Aerios FL GTX is equipped with a minimalist upper made of a single-layer of Cordura mesh and protective TPU films. The combination of these materials grants this hiking shoe with lightness and durability. It is lined with a Gore-Tex membrane for protection from wet trail conditions. This component also prevents the user’s foot from sweating profusely by allowing excess heat and moisture to pass through.

This Arc’teryx low-top model features a rubber cap in its toe box area for extra durability and trail protection. Its closure system employs several eyelets, most of which are hidden to create a streamlined look,  to manage the shoe’s fit. The upper is complemented by a pull tab on the tongue to donning and doffing easier.
