Updates to Mammut T Aenergy High GTX

  • The T Aenergy High GTX offers a solution to virtually every challenge trail and mountain hikers have. Its board-lasted upper has proper protection against the elements, thanks to Gore-Tex.
  • It is engineered with a Mammut-exclusive sole technology, called Rolling Concept. This patented tech is designed to support and cushion the foot during transitions, thus lessening the risk of ankle injuries and reducing movement fatigue.

Mammut T Aenergy High GTX size and fit

A high-cut hiker with a fairly true-to-size fit for men and women is the T Aenergy High GTX. It comes in half and whole sizes in regular width. Giving a no-bunching fit (especially around the instep) and allowing easy on and off is the shoe’s elastic Gore-Tex tongue. What offers a secure and personalized lockdown, on the other hand, is the proprietary Base Fit lacing technology with 2-zone function.

Outsole

This Mammut boot is equipped with the Vibram Scale outsole for surface traction. It is capable of securing the user’s footing over different types of terrain thanks to its debris-shedding rib-like lugs arranged in a scale-like geometry. It is built with a heel brake—a hook-like feature that claws into steep terrain during descents. It is also engineered with a kind of contour that allows the foot to roll with ease.

Midsole

Providing hikers with enough balance on rough terrain with as much cushioning and shock mitigation as possible is the footgear’s tapered midsole. It comes with a cushy wedge made of thermoplastic polyurethane, or TPU. Right on top of this sturdy yet springy component is the boot’s default insole for extra comfort underfoot.

Upper

The Mammut T Aenergy High GTX’s Hybrid Shell (a.k.a upper) is a combination of durable TPU and abrasion-resistant dropstop textile. It has a rubberized border for added protection. Gore-Tex’s Performance Comfort technology is imbued within its bootie, making the footwear waterproof yet breathable. The boot’s ankle, shin, and instep zones are padded with Memo Foam for an improved comfy fit.

Managing the fit is done through the Base Fit lacing system. Its entirety is comprised of metallic hardware (or eyelets) and round, synthetic laces.
