Research Notes: Foot Pockets for a Short Carbon Training Fin
I want to build a short carbon bifin for pool and training.
Before cutting any carbon, I need to choose the foot pocket. These notes collect what I’ve learned so far.
The main questions:
- Which pockets are most commonly used, and why?
- Which ones fit DIY blades without heavy mods?
- How much do blade angle and rails matter for short fins?
- Where can I find solid references?
