Care instructions:

To protect the shoes from dirt, we recommend using a protective/impregnation spray, such as this one from Collonil: Protect & Care. Before spraying the shoes, you can clean them with a damp cloth to prevent dirt from being impregnated.

Size chart:

Here's how to choose the right size (to reduce return shipping and save the environment):
Measure your feet (with your heel against a wall, up to the longest toe). Add 0.5-1.4 cm for extra room inside the shoes and follow the size indications in the size chart. The size chart is the inner measurements of the shoes.
Example: Your foot measurement is 24.8 cm. Choose size 40 (25.7 cm), which will give you 0.9 cm extra room.
