Duckfeet have had the same signature fit for decades. The foot-shaped toe box accommodates all foot types and allows the toes and forefoot to relax; this design also promotes airflow, which helps feet breathe. Duckfeet fit true to size with a medium-to-wide last. Please visit our blog post on fit for all the details.

Duckfeet are unisex-sized with European whole sizes. Compared to U.S. half-sizes, there are fewer European whole sizes and no width scale. Even if you know your usual European size, it’s best to measure your foot for the most accurate fit:

  1. Stand on a ruler with your heel against a wall.
  2. Measure both feet from heel to big toe and compare the larger of the two measurements to the size chart below.
  3. If the measurement equals the length associated with a size, please choose the next size up as the length in the chart is a maximum length.

For 100% premium European sheep wool models, we suggest sizing up by 1 size. Additionally, we offer Wool Insoles that may help with sizing half-sizes.

As your Duckfeet break-in, the leather will soften and slightly stretch; please keep this in mind when sizing.
