Mammut shoe size guide

Here is a size chart specifically designed for Mammut shoes , which lists the dimensions in millimeters.

To accurately determine the size you need, we recommend measuring your foot length in millimeters.

1. Stand against a wall or other 90-degree vertical plane on the floor with your full weight so that your heel touches the wall/plane.
2. Mark where the thumb ends.
3. Measure both feet . If your feet are different sizes, choose the size of the larger foot when determining the size.
4. See the table below.

For hiking shoes, we recommend buying at least 1 - 1.5 sizes larger than your everyday shoe size.

In hiking shoes, your toes should not hit the toe!

This is because after a long walk, your feet swell and an otherwise good-sized shoe will start to squeeze! This is the most common reason why your feet and toes hurt. In the most serious cases, you can even lose your toenails due to the wrong size of hiking shoes.

Example : Measured foot size in millimeters 250 mm or EU 40. Hiking shoes should be chosen starting at 260 mm or EU 41 1/3.
