Full Description

Dual Fit System
AKU's exclusive Dual Fit System allows for optimal fit and quick customization to give you the confidence and performance you need over the most demanding terrain.

Gore-Tex Insulated Comfort + PrimaLoft Aero Gel
Engineered for peak performance on ice and snow, this integrated thermal system layers GORE-TEX waterproof protection with PrimaLoft® and Aerogel to keep your feet warm when the temperature drops.

Vibram Croda Litebase – Crampon Compatible
The Vibram Croda Litebase sole is up to 30% lighter than a traditional sole without sacrificing performance. With full crampon compatibility, this gives you the ability to crush the steepest ice with less fatigue.

Elica Natural Stride System
Our Elica Natural Stride System ensures an anatomical fit to provide better stability and weight distribution across your boot sole to reduce pressure points and encourage better form and performance.

The Aurai DFS Evo GTX is a high-performance alpine boot engineered for the most challenging winter ascents and technical ice climbing.

Dual Fit System

Switch from approach comfort to climbing performance in seconds with AKU’s Dual Fit System—two lacing zones for one perfect fit.

Integrated Aerogel Protection

The Aerogel toe cap acts as a high-tech thermal barrier, blocking the "cold bridge" from ice and crampons to your feet.

Kevlar® Spider Frame

A high-tenacity Kevlar® upper combined with a Spider Frame over-injection creates a shell that is incredibly resistant to impact and abrasion from sharp rock and ice.
