AKU Boot & Shoe Size Chart
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.
