French brand COG focuses on respect for animals, humans and the environment, and  takes great care to ensure that every small component, down to the glue, is free from animal-derived ingredients.

Sizing: we recommend that you take your usual size. If you are between two sizes, have a slightly wide or strong foot on the top, or if you use orthopedic insoles, we advise you to take a size above the one you usually take. Note that the materials of our Athena soften over time.
