Free-diving fins are, of course, designed for free divers, but that doesn’t mean scuba divers can’t use them too. In fact, these super-long kickers have become quite popular among bubble-blowers.

Why would a scuba diver want to use a free-diving fin? To start, the foot pockets are really comfortable. Also, the big flexible blades allow you to use a slow, efficient fin stroke, and they can crank out some serious propulsion when needed. Even better, you can maintain excellent directional control with the slightest flick of an ankle.

However, because they’re so big, they can be pretty unwieldy when it comes to stuffing them in a dive bag. Many of them are designed so their blades can be separated from their foot pockets, which helps when you travel with them. A good indication of the growing popularity of free-diving fins is how many scuba- equipment manufacturers are now offering these fins in their product lines.
