The 450 series is a compact and very swift fin that will allow you to accelerate in a very short time. Available in 3 stiffnesses. E glass fiber will give you a much higher yield than a plastic swimfin. On our Riverboarding blades you'll have specific water rails that protect the blade without reducing its flexibility and hydrodynamics. You can choose a branded closed-heel footpocket or a custom-made open-heel footpocket. This one frees the rotation of the ankle in all directions and thus increases the finning's amplitude and the efficiency thanks to a more precise foot positioning on the blade. Finally, it facilitates direction changes. It takes a little time to get used to it.
These fins are recommended for freestyle. To choose the right stiffness, it is also important to take into account your body size and your level of practice. Compared to a plastic blade, fiberglass will provide you a better propulsion and less fatigue. To choose well, use our help: 'which model and which stiffness for me?'.
