Carbon and carbon composite(sandwich) blades are more lightweight and resilient than fibreglass blades, resulting in better energy efficiency when kicking underwater. On the other hand, fibreglass blades are far less fragile and more durable than carbon blades. 

We advise selecting blade stiffness in correlation with your overall physical structure, your technique, and less with your weight:

Most of our fins and blades are provided in five stiffness, where 1 is soft and 5 is hard.

  • If you weigh under 65 kg (~145 lbs), please select stiffness – Soft
  • If you weigh over 65 kg (~145 lbs), we advise selecting stiffness – Medium 
  • If you weigh over 90 kg (~200 lbs), we advise selecting stiffness – Hard

Again, please, focus more on your physical condition rather than only on your weight.

To learn more about sizing. Please, see our page with a size table.
