Product Description

JBL Polymer Open Heel Fins Long Blade

JBL Longblade Polymer Fins deliver outstanding performance at an unbeatable price. Dive deeper and stay there longer. These fins feature a best in class all new polymer blade. Much like our flagship Xcelerator Blade, they have a stiff foot base that becomes progressively flexible towards the tip. The reinforced base adds further rigidity to critical areas. This balance of stiffness and flex ensures that each kick translates to maximum thrust. These superior qualities are the result of an exclusive polymer blend of nylon and carbon fiber. Polymer blades are set at a 22 degree angle, following the natural geometry of the foot and leg. JBL open heel foot pockets allow for a custom fit without skimping on comfort or kick efficiency. This accomplishment is achieved by molding them from three different rubber densities. The unique properties of each material enable peak performance throughout the pocket. Adjustable back straps ensure the perfect fit for every foot. Side rails offer additional stiffness and channel water down the blade. Water that would “spill” over the edges is converted into further propulsion. Pockets and blades are modular. Secured with screw and blade clips this allows for smaller storage, easy repairs, and upgrades.

  • Exclusive Polymer Blade Formula

I wear US men's size 9 shoes and would use these fins with my Scubapro Everflex Arch hard-sole 5 mm boots, which they claim are for US men's size 8 feet. https://www.divers-supply.com/scubapro-everflex-boot-5mm-arch-black.html Which of the JBL sizes should fit me best? It might be helpful to tell me the inside width of the back of the heel pocket for the size M and L versions. That way, I can compare the measurement to some scuba fins that I know fit me well. Thank you.

If you have a normal to wide foot I would go with the Large in you have a narrow foot then the Medium would fit better.

Can you wear dive boots with these fins?

Hi Bill, thank you for your question on the JBL Polymer Open Heel Fins long Blade. If you have a thinner boot you should be able to wear them but go up a fin size. Let us know if you have anymore questions.

Hi, I am looking to replace my old SporaSub fins that I have had for 20 years. I use them for diving in heavy current. My question is how stiff are the blades. Not looking for anything real flexible. Thanks!

Hi Bill, thank you for your question on the JBL Polymer Open Heel Fins Long Blade. The fin is stiff towards the foot pocket but towards the tip of the fin it is more flexible.

Hi, I would like to use these with a dive boot for rocky shore diving. Will a size 10 hard soled dive boot fit in the XL? If not, how about a size 10 soft soled boot?

Hi David, These are made to fit with a dive boot, .. the size chart shows Large: fits Mens US 10-11 with a standard dive boot. If your boot is heavy duty with a tennis shoe type of sole you may want to go up to an X-large.

These are awesome. Worth the money. Don’t buy online, trying them on is essential. Buy from a local shop where you can learn about them and get the exact fit....You don’t need the safety straps or boots(but buy wet socks online).
