Good to know

  • Garmont designed the Tower Extreme LX GTX with technologies that can overcome technical mountaineering, ice climbing, and mixed routes. It uses a Vibram Mulaz Evo outsole which renders a grippy and stable foothold on trails.
  • The outsole is included in a component set, the Tower Evo. It consists of a 2.5 mm microporous layer, an X-Lite Frame Flex F.Glass insole, PU crampon inserts, and a dual-density PU midsole. This unit acts to render a cushy and comfy ride.
  • It is also equipped with a thermal footbed with Primaloft insulation. A progressive lasting board creates an ideal combination of stiffness and flexibility.
  • The upper is created with Microfiber and Kevlar for durability. Its flex insert, tongue, and the collar are made of a one-piece elastic fabric, lined with stretchy Gore-Tex material. An integrated gaiter, a helix rubber rand, and a pull tab are added too.
  • The Tower Extreme LX GTX has the Anatomically Directed Design (a.d.d.) feature which works with the foot for stability, shock absorption, and propulsion. It includes an asymmetrical cuff, anatomical tongue, and differential ankle pads for stability and comfort. A precision lacing system allows natural foot flexion, and a roomy toe box enhances balance.

The Garmont Tower Extreme LX GTX is a men’s mountaineering boot. It comes in full and half sizes and runs true to size. However, the brand recommends getting a half size up in the likelihood of foot swelling during activities, and if buyers prefer wearing thicker socks.

This mountaineering boot is designed with the Alpine Tech fit which grants a precise, wrapped feel to perform on challenging terrains. It has a roomy toe box to permit natural splaying of the toes for balance and the stretch gaiter also allows for a snugger fit.

The outsole of the Garmont Tower Extreme LX GTX is the Vibram Mulaz Evo. It has a climbing zone at the tip to assist during ascents. The central lugs provide 360-degree traction while the widely spaced channels on the side of the sole prevent dirt from building up. It also acts as a drainage system.

A thermal footbed with Primaloft 200 gram insulation tops the inside of the Tower Extreme LX GTX. A progressive lasting board with varying thickness is added for a uniform rigidity and flexibility regardless of the boot size.

This mountaineering boot has a 2.5 mm microporous layer for a more comfortable environment. It is partnered with a nylon and fiberglass insole which has air vents to eliminate extra weight and maximize heat retention. Tech PU inserts at the heel make the boot crampon-ready and its dual-density expanded PU midsole renders a cushioned and stable ride.

The abrasion-resistant Tower Extreme LX GTX uses a combination of Microfiber and Kevlar for its upper. It has a wrap-around helix rubber rand which protects against abrasions and gives extra grip during climbs. It uses a one-piece stretchy fabric for its flex insert, tongue, and collar. Moreover, it is lined with a Gore-Tex Insulated Comfort membrane which grants breathability and waterproofing. An integrated elastic gaiter helps keep debris out while a heel pull loop assists in donning it on and off.

Garmont also crafted this mid-cut mountaineering boot using their Anatomically Directed Design (a.d.d.) which aims to deliver a stable and comfortable environment. Its cuff is asymmetrically designed for better edging and stability. The tongue runs thicker to the outside and thinner towards the inside to allow it to conform to the top of the foot. Its differential ankle pads lock the heel in place. Its lacing system allows the shoe to flex with the user's foot.
