*While we have enlisted the cooperation of Japanese suit makers to check and draw up our own list of items (in the leftmost column) that will fit with GT, be aware that if boot inners are worn, the sizing will change; fit also depends on the individual form of your feet: for some people the sizes shown may be too large or too small.

Performance

Jet Hole Stabilizers

As pressurized water exits from conventional jet holes, it immediately disperses into the surrounding water. Our patented jet hole stabilizers act as a flow guide, delaying the dispersal of water. This leaves an area of negative water pressure behind the fin allowing your kick to pull out more efficiently.

Semi-Long, Wide Blade Stability

The use of our exclusive 100% made in Japan Kinugawa rubber offers flexibility that effectively transmits the power of your kick to the blade. Compared with other jet style fins, GTʼs bending point occurs closer to the foot pocket displacing enormous volumes of water with every kick. GT promises monstrous power, all while the jet holes actively work to stabilize the blade.

Instant Power

GT offers instantaneous torque power when you most need it. Great for diving with a heavy load, battling tough currents, performing quick getaways, and aiding incapable divers get to shore safely.

Adjustable Spring for Precise Power

Adjustability of up to 4cm for better fitment and ultimately more reliable powerful propulsion.

Dry Suit Compatible Foot Pocket

GTʼs foot pockets are outfitted with large openings allowing for easy wear and removal for almost any drysuit boot to fully be inserted. Grooves on the inside of the pockets help slide your boot in place for a smoother insert.

One-Hand Easy Grip Strap

Spring strap is fixed with a finger handle minimizing the hassle of donning and doffing, even when wearing thick gloves.
