Reference values from norda's official size guide. Choose your US men's (M) or US women's (W) scale and use the corresponding EU size below. Foot length is the heel-to-toe measurement, not the shoe-length label.
Size and fit
For standard 001A and 005 models, norda recommends half a US size above your usual size. For standard 003 models, choose one full US size above your usual size. Follow the individual model's fit advice. When between sizes, choose the larger size.

How to measure your feet
- Wear the socks you intend to run in and stand on a sheet of paper.
- Mark your heel and the tip of your longest toe while standing.
- Measure the distance between the marks and compare it with the foot-length column.
The guide is a size reference; a size appearing in the table does not mean every style is available in that size. The product's size selector shows its listed options.
