Running shoe advice: the right size

What do I have to consider when choosing the shoe size for new running shoes and how can I determine the right size? Our running expert Thomas will show you how it's done.

It depends on the (right) size

The right shoe size has a decisive influence on the fit and running behavior. In contrast to conventional street shoes, the fit of a running shoe should be such that there is still some space in the footbed between the toes and the tip of the shoe. Due to the dynamic rolling movement with every step, the forefoot in particular needs this additional space. If the shoe just fits or is too small, the toes regularly bump against the front edge of the shoe when running. The result: crushing and/or blistering of the toes and overstraining of the shoe material due to the constant pressure of the foot. On the other hand, if the shoe is too big, i.e. there is too much space in front of the toes, the shoe no longer offers the necessary support and the foot "swims" in the footbed.

Determine the right size yourself

There are usually several size specifications on a shoe box: US / UK / EU. How such a size turns out, however, often varies between different manufacturers. Therefore, the size in centimeters - also shown on the shoe box - is the most reliable, because it is independent of the manufacturer and type of shoe model. In the following video, our running expert Thomas explains how you can determine the right size for you for each manufacturer and each model:

That's how it's done

    • Measure both feet using a sheet of paper and a ruler (as shown in the video)
    • add 1.0-1.5 cm to the measured value for the size selection of your running shoe
    • compare your centimeter value with the corresponding size specification (EU/US/UK) from the manufacturer

We wish you many nice kilometers with the new shoes!
