Choosing Bi-fin Foot Pockets - V1 - Short Rails

Proven

Goal

Choose the right freediving foot pockets for DIY carbon blades, focusing on performance-critical features.

Specifications / Dimensions

• Foot pocket rails: short to allow the carbon blade to flex freely
• Blade angle: 20°–33° for better body position and surface gliding
• Attachment system: two-point (blade pocket + screws) for secure hold

Instructions (step-by-step)

1. Check rail length

   • Choose pockets with short or low-profile rails so the blade can bend and return energy efficiently (see rubber fin rails for sourcing options).
   • Avoid long or stiff rails that dampen flex, especially on short training blades.
   • Review current supplier pricing on the bifin foot pockets material page — budget listings can differ from retail stock.

2. Check blade angle

   • Select pockets with 20°–33° blade angle.
   • Larger angles favor surface swimming and gliding.
   • Smaller angles or flat pockets may feel more responsive but are less efficient for pool or surface work.

3. Check attachment system

   • Ensure the pockets use a two-point attachment:
     • Blade slides into the pocket slot
     • Screws lock it in place
   • This system is standard for modern freediving pockets and ensures a secure, repeatable fit.
