The dimensions specified by each manufacturer may vary.

A size chart developed specifically for Mammut shoes is available here, where the dimensions are decoded in millimeters.

To accurately determine the required size, we recommend measuring the length of the leg in millimeters.

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

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

In hiking shoes, the toes must not touch the toe!

This is because after walking for a long time, your feet will swell and an otherwise good size shoe will start to feel tight! This is the most common cause of sore feet and toes. In more serious cases, it is even possible to lose toenails due to an inappropriate hiking shoe size.

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

• Fair Wear. Fair Wear works to ensure fair and safe working conditions in garment factories. The non-profit organization works directly with factories, unions, NGOs and governments to protect workers' rights.
• DWR without PFC. (Durable Water Repellent) water-repellent treatment without PFC. Perfluorinated compounds (PFCs) are often used for waterproofing, but they are virtually non-biodegradable. Mammut is committed to replacing non-biodegradable fabric processing with more sustainable, high-performance alternatives.

How to care for Goretex shoes

Goretex shoes require only a little attention.

In order to preserve the functional properties (water resistance and breathability) of Goretex shoes, as well as the life of the shoe itself as long as possible, they need to be given a little care.

• Clean GoreTex shoes with a soft brush or damp cloth. Do not use bleaches, aggressive cleaning agents and abrasive materials.

• Re-apply water repellent : Over time, the water repellent coating wears off. To restore water repellency, use a spray designed specifically for Gore-Tex shoes, such as Toko Shoe Proof&Care .

• Do not wash in the washing machine . Wash with a mild detergent and allow the shoes to dry in a well-ventilated area away from heat sources and direct sunlight .

• Store in a dry, cool place.
