Product Information
The Seac Motus Single Fin Blade, Ultra Light, High Performance is a single interchangeable replacement blade built for Seac's Motus fin system, made from a special techno-polymer tuned for flexibility and responsiveness and set at the Motus system's 22 degree blade-to-foot angle. It is sold as one blade, not a pair, so it is meant to replace or refresh the blade on an existing Motus fin rather than serve as a complete fin.
Who it is for
This blade is for divers who already own a pair of Seac Motus fins and need to swap a worn or damaged blade, or who want to change the look of their fins with a different color option. It also suits divers who like the Motus foot pocket fit and want the techno-polymer blade offered in the same interchangeable-blade system.
Key details
- Blade-to-foot angle: 22 degrees, matching the full Motus fin geometry
- Material: special techno-polymer formulated for flexibility and responsiveness
- Sold individually as one replacement blade, not as a pair
- Product code: 0730027
- Part of the Motus interchangeable-blade fin line, which also offers a Carbon blade option
Compatibility and sizing
This blade is designed to attach to the Seac Motus closed, full foot pocket, which is made from a dual-density thermoplastic rubber (harder at the sole and ribs, softer around the foot) and is available in foot pocket sizes from UK 3.5/5.5 through 12/13 (US 4.5/5.5 through 12.5/13.5, EU 36/38 through 47/48). Attaching the blade to the foot pocket requires the Motus or Motus Fibrex Blade Fixing Set, which is sold separately.

Frequently Asked Questions
Does the Seac Motus Single Fin Blade come as a pair or a single blade?
It is sold as a single blade, not a pair. If both blades on your Motus fins need replacing, you will need to order two of this item.
Do I need any extra hardware to attach this blade to my fin?
Yes. Attaching the Motus blade to the foot pocket requires the Motus or Motus Fibrex Blade Fixing Set, which is sold separately from the blade itself.
Will this blade fit any foot pocket, or only the Motus foot pocket?
This blade is designed specifically to attach to the Seac Motus closed, full foot pocket, which uses a dual-density thermoplastic rubber construction. It is not a universal replacement blade for other fin brands or models.
What is the difference between this blade and the Motus Carbon blade option?
This blade is made from a special techno-polymer formulated for flexibility and responsiveness; the Carbon blade is a separate option in the same Motus system.
