Zeosian

The Zeosians are a humanoid species from the Alpha or Beta Quadrant planet Zeos. By 2293, members of this species were serving on Starfleet vessels, including one Crewman Dax.

Biology
Zeosians are humanoids with some distinctive facial features, although their most distinguishing characteristic is their large, unusually-shaped feet, which makes it impossible for them to wear the same footwear as most humanoids. This species apparently doesn't have footwear of its own either, making their feet that much more noticeable.
