The Cressi Frog Fin has been a classic in the Cressi range for many years and has a huge following from divers in every corner of the planet. The fin is skillfully made with a combination of a strong copolymer and a soft elastomer. This Composite design delivers efficiency when kicking and exceptional comfort.

The blade originates from the upper part of the foot pocket, with a 20% increase in useful surface area compared to a traditional fin of the same length. A pair of medium-large Frog fins is about 8.5 inches wide by 25 inches long and is made of a Copolymer called ethylene-vinyl-acetate. Ethylene-vinyl-acetate is a state of the art plastic that has good memory. The materials memory allows the fin to snap back into its original position or angle without "going flat". This creates a comfortable gentle kicking fin that delivers nice power, without inducing leg cramps.

Running nearly the fins outside blade length are raised, rubber-like ridges. A pair of smaller ribs runs down the fin's center. These stiff ribs channel water onto the fins blade. As water streams down the leg, it continues in a smooth transition across the length of the fin. There is no water hydroplaning or skidding on either the up or down stroke. No hydroplaning means better power and control for the diver. Each kick's up and down stroke are power movements and drag is minimized.

The Frog's innovative computer designed foot-pocket further aids control and comfort. The pocket's top edge is lined with comfortably soft, curved, rubber-like techno-plastic. Its bottom portion extends back about four inches, giving support under all or most of your foot. When your foot is supported, more of the power from your leg and foot is transferred to the kick.

The Frog is heavier Cressi model. A Heavier fin is more durable and useful for the working diver or instructors who demand strength and comfort. The Cressi Frog also works well when wearing a dry suit or thick cold water wet suit, very popular also in diving schools and excellent for rentals.

It is easy to walk backwards or sideways in Frogs. Small bar-like treads on the bottom provide traction when standing on a slippery surface. The impact resistant plastic quick-release buckles are easy to operate, even with gloves; buckles have a sleek finish and reliably locking mechanism to lock the strap in place. They buckles rotate an impressive 300 degrees, so no matter how high your arch or how high your heel strap is worn, the buckle rotates for a non-crimped, perfect fit.
