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 BOA Adjustment
Designed for the agility required in summer mountaineering, the Croda BOA GTX features the innovative BOA Li2 closure system for a truly customized feel. The dual bidirectional rotors provide independent, precise adjustment around the instep and ankle to ensure a secure and responsive fit.

Vibram Croda Litebase
The Vibram Croda Litebase sole is up to 30% lighter than a traditional sole without sacrificing performance.

GORE-TEX
Engineered for the unpredictable weather of high-altitude summers, this advanced liner ensures your feet stay dry and comfortable in changing conditions. The waterproof and highly breathable membrane maintains an optimal internal microclimate, preventing overheating during intense exertion while blocking moisture from the outside.

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.
