How do the shoes fit? Are there general size charts?

As a rule, our shoes are sized according to your usual shoe size. Through constant testing and optimisation in our technical and development department, we work every day on the optimum fit of our shoes. As part of this process, prototypes of new styles are also worn by employees for several days to ensure comfort in everyday life. However, should there be any deviations in the sizes, we explicitly mention this in the product description of the corresponding item.
