Fins are a piece of Equipment crafted by using the Fabricator. The player must equip them in the feet slot of the paperdoll UI for the player to benefit from them. While equipped, they increase the player's Swimming Speed by +1.4 m/s underwater and +1.85 m/s on the surface.

Fins are easy to craft and should thus be obtained as fast as possible. Fins are useful for exploring and catching fish, notably Boomerangs, given their speed, in the early game.

Fins can be upgraded to Swim Charge Fins or Ultra Glide Fins by using the Modification Station.
