Neptonics Fin Keepers

Overview

Neptonics Fin Keepers are retention straps for full-foot diving fins. They help take up excess space in a loose foot pocket and keep the fin seated more securely during diving.

Fit and use

Place each keeper over the foot and around the back of the fin after putting the fin on. They are particularly useful when a foot pocket fits slightly large or when changing from thicker booties to thinner booties or bare feet leaves additional space inside the pocket.

Reducing movement between the foot and foot pocket helps maintain more direct energy transfer while kicking. The added retention is also useful during surf entries, exits, and rough-water diving where fins may be more easily displaced.
