The Triton combines elements of classic vented fins with an updated design and modern materials. The result is a full-size fin (243⁄4 inches in medium) that’s lightweight and flexible — but with a brisk snap that gives impressive power and acceleration. The large vents direct thrust for efficient kicking in any swim style, while the wide blade offers easy maneuverability. The long base of the foot pocket provides stability and comfort. It's also available with spring straps.

Designed for cold-water divers, the ARA has slightly larger foot pockets to accommodate drysuit boots. The blades, likewise, are full size — long and wide, for good power and acceleration — and are available in a Soft Blade version. The elastic bungee straps have large, soft heel pads for comfort and a secure fit, and the oversize finger loop on the strap makes them a cinch to get on and off.

The Propulsion has a long blade with three water channels that run almost its full length and work with ribs on the side rails at the tip to redirect water for optimum thrust. The supple blade provides power without stressing leg muscles. The deep pocket has a firm bottom for stability, a flexible top section for a nonchafing fit, and two-position locks on the straps to prevent accidental release.

Scubapro has continued to refine the unique design of the original Nova, which allows the whole blade to pivot for maximum thrust. The latest version has reshaped blades for efficiency in all kicking styles, and redesigned flex sections connecting blade- to-foot pocket for greater durability. There’s also a nonskid material on the foot pocket and a selection of funky new colors to choose from.

The long, trusslike side rails on the Fiji brace the blade for just the right combination of stiffness and flexibility, while the large cutouts between the foot pocket and rails reduce drag through the water. A soft, deep pocket in the center of the blade scoops water for added drive. At just a shade over 21 inches in size medium, the Fiji is an attractive travel companion.

While the Vapor fin might look like a standard open- heel fin, it’s actually made to wear on bare feet. It’s comfortable, with a soft foot pocket and neoprene heel pad on the adjustable strap. The vented blades provide a good mix of power and acceleration without overtaxing calf muscles. The Vapor’s compact dimensions (22 inches long in the largest size) make it a fin to consider for travel — and the price is right too.

The XT has used a tried-and-true design and construction for more than 20 years, but it now comes with a new stainless spring strap buckle that makes the most of the fin’s power and stability. Though it’s on the stiffer side of the scale, the XT’s blade also has a notice- able snap to it that gives it good drive and acceleration. And the new strap-buckle boot-hugging foot pocket provides rock-solid stability as well as a comfortable, secure fit.

The Accel is formed from a solid piece of synthetic rubber that makes it noticeably lighter than most fins and gives it a brisk snap to its kick. The deep side rails block water from spilling off the sides of the blade and direct thrust for forward drive. The stretch straps are easy to adjust and available in seven colors. The suitcase-friendly Accel measures just 21 inches in size regular.

An innovative take on the conventional paddle fin, the Blade is made of alternating bands of hard and soft materials, with long, tapering side rails that support the huge, dished channel that takes up most of the blade. The foot pocket’s sole plate ties into the fin’s whole structure for rock-solid stability. Winglet stabilizers at the tips of the side rails keep the fins tracking straight throughout the kick cycle for top power and efficiency.

The top of the Sumi’s blade is molded with six channeling guides to direct water where it provides extra drive with each kick. The blade is positioned high on the foot pocket and set at an angle of 22 degrees for efficiency and reduced leg and ankle stress. The foot pocket is deep and soft, and the bottom has thick, soft tread for an effective nonskid grip on slippery boat decks.
