EX1 fins – Stiffness hard

BecauseÉ agility needs power, power needs control and accuracy needs to be delivered with efficiency.
XDeep EX1 Jet-Type Fins are a redesign of the classic Jet Fin, giving improvements in both shape and materials – taking an iconic fin design into the future.
EX1 Fins are shorter and slightly wider (24.5cm) than most rubber jet fins, designed for precise position control, maneuverability and power transmission through the full length of the blade. This is ideal for wreck and cave divers, photographers and all tec divers where both power and precision are important. Vents between the foot pocket and the blade reduce effort on the downwards stroke and improve efficiency, reducing effort and fatigue.
The EX1 fins are made from a modern techno-polymer chosen for superior performance compared to traditional rubber. The compound is also less succeptible to changes in stiffness and performance in warm versus cold water. The fins also feature the convenience of steel spring straps. This is a high quality product, made to last for years. Refer to the XDEEP website for more details.
Hard compound are for divers with stronger legs that was precision and power.
Medium compound versions of these fins provide similar precision and control but are more suited to moderate leg strength.
Soft compound fins are more suited to divers using a flutter kick but wanting more precise control than typical recreational fins. These are available by special order only, please contact us for details.
Selecting your fin size. The size of fin that you need will depend on the size of the dive boots or dry suit boots that you’re wearing, including sole thickness. The following table lists the internal width and height of the fin pocket across the ball of the foot and the opening. Being rubber, the foot pocket will shape around your boot, so these measurements are approximate figures only. The critical measurement is the Width (at ball) – measure the maximum width of your dive boot sole and select the fin size with the same or larger Width (at ball) in the table, then check that the other dimensions are ‘about right’.

Please select the correct size fin. Incorrectly fitting fins, which have not been used, may be exchanged but do not qualify for free return shipping. These fins weigh 2.6 – 2.8 kg and, due to the high dimensional weight for shipping, the cost to return these could be relatively high; we’d much prefer that you select the right fins the first time!
