Mares Avanti Superchannel FF Full Foot Diving Fins

Mares Avanti Superchannel FF: Full-Foot Fins for Recreational Divers and Snorkelers

The Mares Avanti Superchannel FF is a full-foot fin built for warm-water recreational diving and snorkeling. You slip it on bare or with a thin sock, no straps to adjust, no buckles to fiddle with.

If you dive in warm water, rent equipment on holiday, or snorkel regularly and want a fin that travels well without giving up real propulsion, this is worth a close look.

How the Blade Actually Works

The blade is made from Tecralene, a material Mares uses for its mix of flexibility and resilience. It bends under load and springs back, which is what drives you forward without demanding a hard, exhausting kick.

Running through that blade are three channels created by soft longitudinal inserts. As you kick, water is directed along these channels rather than spilling off the sides. The result is more of your effort converted into forward movement, and less wasted in turbulence.

In practical terms, you should find a slower, more relaxed kick cadence gets you where you want to go. That matters for air consumption and for keeping your heart rate down on longer swims.

The Foot Pocket

This is a closed, full-foot pocket, not an open-heel design. There is no strap. You pull it on directly, which is why Mares calls it the FF (full foot) version of the Superchannel line.

The pocket is made from thermoplastic rubber and is shaped with an orthopedic profile, meaning it follows the natural contours of the foot rather than clamping straight across it. For a fin you might wear for an hour or more at a stretch, that shape matters.

It fits bare feet or thin neoprene socks. If you plan to dive in cooler conditions and need a thick boot, this is not the right fin. Full-foot fins are designed for warm water, and a thick boot will either prevent entry or create a sloppy fit that costs you efficiency and comfort.

Size and Travel

The Avanti Superchannel FF is compact relative to its thrust output. At 0.7 kg per fin, it is light enough to pack without guilt, and the shorter blade profile means it fits into a bag alongside the rest of your gear without dominating the space.

That makes it a practical choice if you travel to dive rather than diving from a local site with your own vehicle. The performance does not feel like a compromise for the size.

Who This Fin Suits

The Superchannel FF works well for recreational divers in warm water who want a reliable, efficient fin they can also pack for a trip. It suits snorkelers who want real propulsion rather than a bargain-bin paddle.

It is also a reasonable choice if you are newly certified and diving in tropical or Mediterranean conditions, where a full-foot fin is appropriate and you are still developing your kick technique. The channel design rewards a smooth, steady kick rather than a frantic one, which is good habit-forming.

It is not suited to cold-water diving with thick boots, or to technical or overhead environments where an open-heel fin with a proper spring strap is the standard for good reason.

One Honest Note on Fit

Full-foot fins fit differently across brands, and sizing can be inconsistent between manufacturers. Because the pocket is a pull-on with no adjustment, getting the size right matters more here than with an open-heel fin. If you are between sizes, lean toward the larger option and plan to wear a thin sock to take up any slack. A fin that is too tight will cut off circulation on longer dives; one that is too loose will move around and blister your heel.
