A shorter blade and lower ribs for a lighter kick
The blade is shorter than ordinary fins, so the rubber flexes for a shorter time, for nimble, efficient finning. The ribs are lower so the rubber flexes more easily, for a lighter kick.
A light, agile strap fin for divers of any level
MEW CYPHER is GULL's all-round strap fin for divers of any skill level who prefer a lighter, agile kick. The blade is shorter than ordinary fins, the ribs are lower so the rubber flexes more easily, and a protruding tip adds drive while the kick stays relatively light. A long sole and high instep wrap your whole boot. GULL says it suits divers who value efficiency, skin diving or scuba.

The blade is shorter than ordinary fins, so the rubber flexes for a shorter time, for nimble, efficient finning. The ribs are lower so the rubber flexes more easily, for a lighter kick.

The centre of the tip sticks out to add power to every kick, while the fins stay easy to manage and relatively light to kick.
A long sole and high instep wrap your whole boot with the feel of a full-foot fin: comfortable, with a direct feel from kick to drive.
The short blade keeps the fins compact and light, so you move with agility, are less likely to damage coral or marine life, and can get them on and off in tight spaces such as a cramped boat. A thicker sole with a new tread pattern grips better.

Yes. GULL says MEW CYPHER suits divers of any skill level who prefer a lighter, agile kick; the short blade and lower ribs make the kick lighter, for skin diving or scuba. If you dive barefoot, see GULL MEW instead.
GULL says the protruding tip captures good drive while the kick stays relatively light, and the blade, shorter than ordinary fins, makes finning nimble and efficient.
Each fin weighs 877 g (S) to 1,080 g (L), measured on black, and is 507–540 mm long depending on size.
Almost. According to GULL, Tourmaline Pink, Shell Blue and Iris Purple come in S and M only; every other colour comes in S–L.
