Updates to Under Armour Infil Hike GTX

  • The Infil Hike GTX is designed with the lightness of a basketball shoe yet has a set of technologies that allow hiking enthusiasts to negotiate the challenging terrain. It comes engineered with a TPU stability chassis to keep the heel in place and bolster the footwear’s overall support.
  • Giving users enough underfoot protection on the trail is the boot’s full-length midsole. What delivers adequate grip on rough and slippery surfaces, on the other hand, is a rubber outsole from Vibram.

Size and fit

A generally true-to-size, mid-cut day hiking gear for men is the Under Armour Infil Hike GTX. It comes in full and half sizes in standard width. The footwear’s lace-up closure allows for a customized and secure lockdown, while its Anafoam overlay, which is anatomically molded around the upper, provides a precise fit.


The Under Armour Infil Hike GTX waterproof boot uses a Vibram outsole with MegaGrip compound to prevent wearers from losing their footing over challenging terrain. V-shaped lugs are engineered at opposing angles along its forefoot and rearfoot borders to deliver sufficient slip resistance during ascents and descents. The blocky lugs at its center only add to its grip effectiveness.


This UA hiker has a full-length midsole made of EVA (or ethylene-vinyl acetate) for ground protection, cushioning, and stability. Under Armour designers placed a wishbone TPU plate within its frame to improve the footwear’s torsional rigidity, thereby allowing wearers to achieve a steady balance on the trickier parts of the trail.

Contributing to the underfoot cushioning brought forth by the midsole is the boot’s default sockliner. It is imbued with Cupron’s Anti-Fungal Pro Fibers, rendering it capable of dealing with odor and eliminating 99.9% of athlete’s foot fungus.


Abrasion-resistant textile is what mostly makes up the Infil Hike GTX’s over-the-ankle upper. The Anafoam overlay built around it gives it improved support, while the rubber overlay engineered at its heel enhances its durability. On the tip of its forefoot is a molded rubber cap for extra toe protection. Its liner is built with a breathable Gore-Tex membrane, allowing the shoe to remain airy yet watertight in the inclement weather and wet environments.

The upper’s lace-up closure consists of fabric loops and metallic hooks for eyelets and string-like synthetic laces. Its tongue and heel come with pull loops to help speed up the on-and-off process.
