A shorter profile is the defining comparison for the Moloko Flexi River US Fin. This plastic fin has some flex, a listed depth of 4.5 inches and a 7.25-inch base length. Check those measurements and the fixing against your board when choosing a replacement.
Why choose it?
- Published 4.5-inch depth gives a clear comparison point.
- Plastic construction allows some flex.
- A separate short-profile choice within the Moloko range.
How the details help
Fin depth, base length and shape influence the setup together. A shorter fin changes the area available beneath the board, so it should not be selected solely because it looks less likely to contact the bottom. The product name is not route or whitewater suitability advice.

Questions before you buy
Does a shorter fin make a shallow route suitable?
No. Water conditions, hazards, access and experience remain separate considerations.
Is the base length the same as the depth?
No. They describe different parts of the fin and both may be needed for a fit check.
