Size Guide

For over 40 years, AKU has been handcrafting hiking, mountaineering, hunting, and tactical footwear in Italy. Every pair is built on lasts modelled from real feet — which makes finding your perfect size simple.

How to Measure Your Feet

Step onto a piece of paper and mark behind your heel and in front of your longest toe.
Do this for both feet and measure the distance between the lines in centimeters. This measurement is your Mondopoint.
Using the measurement from your longest foot, find your corresponding size in the chart below.

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.
