Fins 101: Choosing the Right Fin

Your fins are one of the most important pieces of scuba gear you’ll own — they determine your comfort, efficiency, and control underwater. Whether you’re gliding along a reef or working through a current, the right pair can make all the difference.

Full Foot Fins: A Limited Fit

While full foot fins can look simple and lightweight, they often come with drawbacks. It’s difficult to find a pair that fits comfortably, and because they’re worn barefoot, they exclude you from the protection dive boots provide. That means no defense against sharp rocks, hot docks, or slipping on a boat deck. For most divers, especially in open water, we recommend skipping full foot fins.

Split Fins: Easy, But Not for Every Diver

Split fins are designed to reduce resistance by cutting through the water with less effort — great for casual swimming, but they don’t provide enough thrust for strong currents or precise maneuvering. When you need power, stability, and control, split fins often fall short.

Adjustable Open-Heel Fins: The Best All-Around Choice

Open-heel fins, worn with dive boots, give you the flexibility and protection needed for nearly any environment. They’re easier to size correctly, offer better foot support, and allow you to switch out boots depending on water temperature or surface conditions.

Why We Love the TUSA Hyflex System

The TUSA Hyflex fin system combines the comfort and versatility of open-heel fins with advanced materials that balance power and flexibility. The detachable blade design makes travel easier, while the multi-compound construction delivers efficient thrust with every kick. It’s a system that adapts to your diving needs and packs perfectly in your gear bag.
